Chapter XI: Part 11

DRAWING AND QUARTERING, part of the penalty anciently ordained in England for treason. Until 1870 the full punishment for the crime was that the culprit be dragged on a hurdle to the place of execution; that he be hanged by the neck but not till he was dead; that he should be disembowelled or drawn and his entrails burned before his eyes; that his head be cut off and his body divided into four parts or quartered. This brutal penalty was first inflicted in 1284 on the Welsh prince David, and on Sir William Wallace a few years later. In Richard III.'s reign one Collingbourne, for writing the famous couplet "The Cat, the Rat and Lovel the Dog, Rule all England under the Hog," was executed on Tower Hill. Stow says, "After having been hanged, he was cut down immediately and his entrails were then extracted and thrown into the fire, and all this was so speedily done that when the executioners pulled out his heart he spoke and said 'Jesus, Jesus.'" Edward Marcus Despard and his six accomplices were in 1803 hanged, drawn and quartered for conspiring to assassinate George III. The sentence was last passed (though not carried out) upon the Fenians Burke and O'Brien in 1867. There is a tradition that Harrison the regicide, after being disembowelled, rose and boxed the ears of the executioner.

DRAWING-ROOM (a shortened form of "with-drawing room," the longer form being usual in the 16th and 17th centuries), the English name generally employed for a room used in a dwelling-house for the reception of company. It originated in the setting apart of such a room, as the more private and exclusive preserve of the ladies of the household, to which they withdrew from the dining-room. The term "drawing-room" is also used in a special sense of the formal receptions or "courts" held by the British sovereign or his representative, at which ladies are presented, as distinguished from a "levee," at which men are presented.

DRAYTON, MICHAEL (1563-1631), English poet, was born at Hartshill, near Atherstone, in Warwickshire in 1563. Even in childhood it was his great ambition to excel in writing verses. At the age of ten he was sent as page into some great family, and a little later he is supposed to have studied for some time at Oxford. Sir Henry Goodere of Powlesworth became his patron, and introduced him to the countess of Bedford, and for several years he was esquire to Sir Walter Aston. How the early part of his life was spent, however, we possess no means of ascertaining. It has been surmised that he served in the army abroad. In 1590 he seems to have come up to London, and to have settled there.

In 1591 he produced his first book, _The Harmony of the Church_, a volume of spiritual poems, dedicated to Lady Devereux. The best piece in this is a version of the Song of Solomon, executed with considerable richness of expression. A singular and now incomprehensible fate befell the book; with the exception of forty copies, seized by the archbishop of Canterbury, the whole edition was destroyed by public order. It is probable that he had come up to town laden with poetic writings, for he published a vast amount within the next few years. In 1593 appeared _Idea: The Shepherd's Garland_, a collection of nine pastorals, in which he celebrated his own love-sorrows under the poetic name of Rowland. The circumstances of this passion appear more distinctly in the cycle of 64 sonnets, published in 1594, under the title of _Idea's Mirror_, by which we learn that the lady lived by the river Ankor in Warwickshire. It appears that he failed to win his "Idea," and lived and died a bachelor. In 1593 appeared the first of Drayton's historical poems, _The Legend of Piers Gaveston_, and the next year saw the publication of _Matilda_, an epical poem in rhyme royal. It was about this time, too, that he brought out _Endimion and Phoebe_, a volume which he never republished, but which contains some interesting autobiographical matter, and acknowledgments of literary help from Lodge, if not from Spenser and Daniel also. In his _Fig for Momus_, Lodge has reciprocated these friendly courtesies. In 1596 Drayton published his long and important poem of _Mortimerades_, which deals with the Wars of the Roses, and is a very serious production in _ottava rima_. He afterwards enlarged and modified this poem, and republished it in 1603 under the title of _The Barons' Wars_. In 1596 also appeared another historical poem, _The Legend of Robert, Duke of Normandy_, with which _Piers Gaveston_ was reprinted. In 1597 appeared _England's Heroical Epistles_, a series of historical studies, in imitation of those of Ovid. These last poems, written in the heroic couplet, contain some of the finest passages in Drayton's writings.

With the year 1597 the first half of the poet's literary life closes. He had become famous by this rapid production of volumes, and he rested on his oars. It would seem that he was much favoured at the court of Elizabeth, and he hoped that it would be the same with her successor. But when, in 1603, he addressed a poem of compliment to James I., on his accession, it was ridiculed, and his services rudely rejected. His bitterness of spirit found expression in a satire, _The Owl_, which he printed in 1604, although he had no talent in this kind of composition. Not much more entertaining was his scriptural narrative of _Moses in a Map of his Miracles_, a sort of epic in heroics printed the same year. In 1605 Drayton reprinted his most important works, that is to say, his historical poems and the _Idea_, in a single volume which ran through eight editions during his lifetime. He also collected his smaller pieces, hitherto unedited, in a volume undated, but probably published in 1605, under the title of _Poems Lyric and Pastoral_; these consisted of odes, eclogues, and a fantastic satire called _The Man in the Moon_. Some of the odes are extremely spirited. In this volume he printed for the first time the famous _Ballad of Agincourt_.

He had adopted as early as 1598 the extraordinary resolution of celebrating all the points of topographical or antiquarian interest in the island of Great Britain, and on this laborious work he was engaged for many years. At last, in 1613, the first part of this vast work was published under the title of _Poly-Olbion_, eighteen books being produced, to which the learned Selden supplied notes. The success of this great work, which has since become so famous, was very small at first, and not until 1622 did Drayton succeed in finding a publisher willing to undertake the risk of bringing out twelve more books in a second part. This completed the survey of England, and the poet, who had hoped "to crown Scotland with flowers," and arrive at last at the Orcades, never crossed the Tweed. In 1627 he published another of his miscellaneous volumes, and this contains some of his most characteristic and exquisite writing. It consists of the following pieces: _The Battle of Agincourt_, an historical poem in _ottava rima_ (not to be confused with his ballad on the same subject), and _The Miseries of Queen Margaret_, written in the same verse and manner; _Nimphidia, the Court of Faery_, a most joyous and graceful little epic of fairyland; _The Quest of Cinthia_ and _The Shepherd's Sirena_, two lyrical pastorals; and finally _The Moon Calf_, a sort of satire. Of these _Nimphidia_ is perhaps the best thing Drayton ever wrote, except his famous ballad on the battle of Agincourt; it is quite unique of its kind and full of rare fantastic fancy.

The last of Drayton's voluminous publications was _The Muses' Elizium_ in 1630. He died in London on the 23rd of December 1631, was buried in Westminster Abbey, and had a monument placed over him by the countess of Dorset, with memorial lines attributed to Ben Jonson. Of the particulars of Drayton's life we know almost nothing but what he himself tells us; he enjoyed the friendship of some of the best men of the age. He corresponded familiarly with Drummond; Ben Jonson, William Browne, George Wither and others were among his friends. There is a tradition that he was a friend of Shakespeare, supported by a statement of John Ward, once vicar of Stratford-on-Avon, that "Shakespear, Drayton and Ben Jonson had a merry meeting, and it seems, drank too hard, for Shakespear died of a feavour there contracted." In one of his poems, an "elegy" or epistle to Mr Henry Reynolds, he has left some valuable criticisms on poets whom he had known. He was even engaged in the labour of the dramatists; at least he had a share, with Munday, Chettle and Wilson, in writing _Sir John Oldcastle_, which was printed in 1600. That he was a restless and discontented, as well as a worthy, man may be gathered from his own admissions.

The works of Drayton are bulky, and, in spite of the high place that he holds in critical esteem, it cannot be pretended that he is much read. For this his ponderous style is much to blame. The _Poly-Olbion_, the most famous but far from the most successful of his writings, is tedious and barren in the extreme. It was, he tells us, a "Herculean toil" to him to compose it, and we are conscious of the effort. The metre in which it is composed, a couplet of alexandrines, like the French classical measure, is wholly unsuited to the English language, and becomes excessively wearisome to the reader, who forgets the learning and ingenuity of the poet in labouring through the harsh and overgrown lines. His historical poems, which he was constantly rewriting and improving, are much more interesting, and often rise to a true poetic eloquence. His pastorals are brilliant, but overladen with colour and sweet to insipidity. He is, with the one magnificent exception of "Since there's no help, come let us kiss and part," which was first printed in 1619, an indifferent sonneteer. The poet with whom it is most natural to compare him is Daniel; he is more rough and vigorous, more varied and more daring than the latter, but Daniel surpasses him in grace, delicacy and judgment. In their elegies and epistles, however, the two writers frequently resemble each other. Drayton, however, approaches the very first poets of the Elizabethan era in his charming _Nimphidia_, a poem which inspired Herrick with his sweet fairy fancies and stands alone of its kind in English literature; while some of his odes and lyrics are inspired by noble feeling and virile imagination.

In 1748 a folio edition of Drayton's complete works was published
under the editorial supervision of William Oldys, and again in 1753
there appeared an issue in four volumes. But these were very
unintelligently and inaccurately prepared. A complete edition of
Drayton's works with variant readings was projected by Richard Hooper
in 1876, but was never carried to a conclusion; a volume of
selections, edited by A. H. Bullen, appeared in 1883. See especially
Oliver Elton, _Michael Drayton_ (1906). (E. G.)

DREAM (from a root _dreug_, connected with Germ. _trugen_, to deceive), the state of consciousness during sleep; it may also be defined as a hallucination or illusion peculiarly associated with the condition of sleep, but not necessarily confined to that state. In sleep the withdrawal of the mind from the external world is more complete and the objectivity of the dream images is usually unquestioned, whereas in the waking state the hallucination is usually recognized as such; we may, however, be conscious that we are dreaming, and thus in a measure be aware of the hallucinatory character of our percepts. The physiological nature of sleep (q.v.; see also MUSCLE AND NERVE) and of dreaming is obscure. As a rule the control over the voluntary muscles in dreams is slight; the sleep-walker is the exception and not the rule, and the motor activity represented in the dream is seldom realized in practice, largely, no doubt, because we are ignorant, under these circumstances, of the spatial relations of our bodies. Among the psychological problems raised by dreams are the condition of attention, which is variously regarded as altogether absent or as fixed, the extent of mental control, and the relation of ideas and motor impulses. There is present in all dreams a certain amount of dissociation of consciousness, or of obstructed association, which may manifest itself in the preliminary stage of drowsiness by such phenomena as the apparent transformation or inversion of the words of a book. We may distinguish two types of dreams, (a) representative or centrally initiated, (b) presentative or due to the stimulation of the end organs of sense. In both cases, the dream having once been initiated, we are concerned with a process of reasoning, i.e. the combination of ideas suggested by resemblances or other associative elements. The false reasoning of dreams is due in the first place to the absence, to a large extent, of the memory elements on which our ordinary reasoning depends, and, secondly, to the absence of sensory elements.

_Objectivity of Dreams._--In waking life we distinguish ideas or mental images from real objects by the fact that we are able under normal circumstances to dismiss the former at will. In sleep, on the other hand, we have, in the first place, no real objects with which to compare the images, which therefore take on a character of reality comparable to the hallucination of waking life; moreover, powers of visualization and other faculties are enhanced in sleep, so that the strength of dream images considerably exceeds those of the mental images of the ordinary man; changes in powers of attention, volition and memory help to increase the hallucinatory force of the dream. In the second place, the ideas of our dreams are presented in the form of images, which we are unable to dismiss; we therefore mistake them for realities, exactly as the sufferer from delirium tremens in waking life is apt to regard his phantoms as real.

_Relations of Dreaming and Sleep._--It has been maintained by Hamilton and others (see below, Modern Views) that dreams invariably accompany sleep, and that we always find ourselves dreaming when we are awakened. But even if it were true that dreams were invariably experienced at the moment of waking, this would not by any means establish the invariable concomitance of dreams and sleep of all sorts; at most it would show that imperfect sleep is a condition of dreaming; in the same way, dreams before wakening, known to have taken place either from the recollection of the dreamer or from the observation of another person, may clearly be due to imperfect wakening, followed by a deepening of sleep. It is, however, by no means true that awakening from sleep is invariably accompanied by a dream; in considering the question it must be recollected that it is complicated by the common experience of very rapid forgetfulness of even a vivid and complicated dream, only the fact of having dreamt remaining in the memory; it is clear that amnesia may go so far that even the fact of dreaming may be forgotten. On the whole, however, there appear to be no good grounds for the assertion that we always dream when we are asleep. On the other hand, there is no proof that partial awakening is a necessary condition of dreaming.

_Representative Dreams._--Centrally initiated dreams may be due to a kind of automatic excitation of the cerebral regions, especially in the case of those clearly arising from the occupations or sensations of the day or the hours immediately preceding the dream. To the same cause we may attribute the recalling of images apparently long since forgotten. Some of these revivals of memory may be due to the fact that links of association which are insufficient to restore an idea to consciousness in the waking state may suffice to do so in sleep. Just as a good visualizer in his waking moments may call up an object never clearly seen and yet distinguish the parts, so in sleep, as L. F. A. Maury (1817-1892) and others have shown, an image may be more distinct in a dream than it was when originally presented (see also below, Memory).

_Presentative Dreams._--The dreams due to real sensations, more or less metamorphosed, may arise (a) from the states of the internal organs, (b) from muscular states, (c) from subjective sensations due to the circulation, &c., or (d) from the ordinary cause of the action of external stimuli on the organs of sense.

(a) The state of the stomach, heart, &c., has long been recognized as important in the causation of dreams (see below, Classical Views). The common sensation of flying seems to be due in many cases to the disturbance of these organs setting up sensations resembling those felt in rapidly ascending or descending, as in a swing or a lift. Indigestion is a frequent cause of nightmare--the term given to oppressive and horrible dreams--and bodily discomfort is sometimes translated into the moral region, giving rise to the dream that a murder has been committed. (b) Dreams of flying, &c., have also been attributed to the condition of the muscles during sleep; W. Wundt remarks that the movements of the body, such as breathing, extensions of the limbs and so on, must give rise to dream fancies; the awkward position of the limbs may also excite images. (c) Especially important, probably, for the dreams of the early part of the night are the retinal conditions to which are due the _illusions hypnagogiques_ of the preliminary drowsy stage; but probably Ladd goes too far in maintaining that entoptic stimuli, either intra- or extra-organic in origin, condition all dreams. _Illusions hypnagogiques_, termed popularly "faces in the dark," of which Maury has given a full account, are the not uncommon sensations experienced, usually visual and seen with both open and closed eyes, in the interval between retiring to rest and actually falling asleep; they are comparable to the crystal-gazing visions of waking moments; though mainly visual they may also affect other senses. Besides the eye the ear may supply material for dreams, when the circulation of the blood suggests rushing waters or similar ideas. (d) It is a matter of common observation that the temperature of the surface of the body determines in many cases the character of the dreams, the real circumstances, as might be expected from the general character of the dream state, being exaggerated. In the same way the pressure of bed-clothes, obstruction of the supply of air, &c., may serve as the starting-point of dreams. The common dream of being unclothed may perhaps be due to this cause, the sensations associated with clothing being absent or so far modified as to be unrecognizable. In the same way the absence of foot-gear may account for some dreams of flying. It is possible to test the influence of external stimuli by direct experiment; Maury made a number of trials with the aid of an assistant.

_Rapidity of Dreams._--It has often been asserted that we dream with extreme rapidity; but this statement is by no means borne out by experiment. In a trial recorded by J. Claviere the beginning of the dream was accurately fixed by the sounding of an alarm clock, which rang, then was silent for 22 seconds, and then began to ring continuously; the dream scene was in a theatre, and he found by actual trial that the time required in ordinary life for the performance of the scenes during the interval of silence was about the same as in ordinary life. Spontaneous dreams seem to show a different state of things; it must be remembered that (1) dreams are commonly a succession of images, the number of which cannot be legitimately compared with the number of extra-organic stimuli which would correspond to them in ordinary life; the real comparison is with mental images; and (2) the rapidity of association varies enormously in ordinary waking life. No proof, therefore, that some dreams are slow can show that this mentation in others is not extremely rapid. The most commonly quoted case is one of Maury's; a bed-pole fell on his neck, and (so it is stated) he dreamt of the French Revolution, the scenes culminating in the fall of the guillotine on his neck; this has been held to show that (1) dreams are extremely rapid; and (2) we construct a dream story leading up to the external stimulus which is assumed to have originated the dream. But Maury's dream was not recorded till many years after it had occurred; there is nothing to show that the dream, in this as in other similar cases, was not in progress when the bed-pole fell, which thus by mere coincidence would have intervened at the psychological moment; Maury's memory on waking may have been to some extent hallucinatory. But there are records of waking states, not necessarily abnormal, in which time-perception is disturbed and brief incidents seem interminably long; on the other hand, it appears from the experiences of persons recovered from drowning that there is great rapidity of ideation before the extinction of consciousness; the same rapidity of thought has been observed in a fall from a bicycle.

_Reason in Dreams._--Studies of dreams of normal individuals based on large collections of instances are singularly few in number; such as there are indicate great variations in the source of dream thoughts and images, in the coherence of the dream, and in the powers of memory. In ordinary life attention dominates the images presented; in dreams heterogeneous and disconnected elements are often combined; a resemblance need not even have been consciously recognized for the mind to combine two impressions in a dream; for example, an aching tooth may (according to the dream) be extracted, and found to resemble rocks on the sea-shore, which had not struck the waking mind as in any way like teeth. Incongruence and incoherence are not, however, a necessary characteristic of dreams, and individuals are found whose dream ideas and scenes show a power of reasoning and orderliness equal to that of a scene imagined or experienced in ordinary life. In some cases the reasoning power may attain a higher level than that of the ordinary conscious life. In a well-authenticated case Professor Hilprecht was able in a dream to solve a difficulty connected with two Babylonian inscriptions, which had not previously been recognized as complementary to each other; a point of peculiar interest is the dramatic form in which the information came to him--an old Babylonian priest appeared in his dream and gave him the clue to the problem (see also below, Personality).

_Memory in Dreams._--Although prima facie the dream memory is fragmentary and far less complete than the waking memory, it is by no means uncommon to find a revival in sleep of early, apparently quite forgotten, experiences: more striking is the recollection in dreams of matters never supraliminally (see SUBLIMINAL SELF) apperceived at all.

The relation between the memory in dreams and in the hypnotic trance is curious: suggestions given in the trance may be accepted and then forgotten or never remembered in ordinary life; this does not prevent them from reappearing occasionally in dreams; conversely dreams forgotten in ordinary life may be remembered in the hypnotic trance. These dream memories of other states of consciousness suggest that dreams are sometimes the product of a deeper stratum of the personality than comes into play in ordinary waking life. It must be remembered in this connexion that we judge of our dream consciousness by our waking recollections, not directly, and our recollection of our dreams is extraordinarily fragmentary; we do not know how far our dream memory really extends. Connected with memory of other states is the question of memory in dreams of previous dream states; occasionally a separate chain of memory, analogous to a secondary personality, seems to be formed. We may be also conscious that we have been dreaming, and subsequently, without intermediate waking, relate as a dream the dream previously experienced. In spite of the irrationality of dreams in general, it by no means follows that the earlier and later portions of a dream do not cohere; we may interpolate an episode and again take up the first motive, exactly as happens in real life. The strength of the dream memory is shown by the recurrence of images in dreams; a picture, the page of a book, or other image may be reproduced before our eyes several times in the course of a dream without the slightest alteration, although the waking consciousness would be quite incapable of such a feat of visualizing. In this connexion may be mentioned the phenomenon of redreaming; the same dream may recur either on the same or on different nights; this seems to be in many cases pathological or due to drugs, but may also occur under normal conditions.

_Personality._--As a rule the personality of the dreamer is unchanged; but it also happens that the confusion of identity observed with regard to other objects embraces the dreamer himself; he imagines himself to be some one else; he is alternately actor and observer; he may see himself playing a part or may divest himself of his body and wander incorporeally. Ordinary dreams, however, do not go beyond a splitting of personality; we hold conversations, and are intensely surprised at the utterances of a dream figure, which, however, is merely an _alter ego_. As in the case of Hilprecht (see above) the information given by another part of the personality may not only appear but actually be novel.

_Supernormal Dreams._--In addition to dreams in which there is a revival of memory or a rise into consciousness of facts previously only subliminally cognized, a certain number of dreams are on record in which telepathy (q.v.) seems to play a part; much of the evidence is, however, discounted by the possibility of hallucinatory memory. Another class of dreams (prodromic) is that in which the abnormal bodily states of the dreamer are brought to his knowledge in sleep, sometimes in a symbolical form; thus a dream of battle or sanguinary conflict may presage a haemorrhage. The increased power of suggestion which is the normal accompaniment of the hypnotic trance may make its appearance in dreams, and exercise either a curative influence or act capriciously in producing hysteria and the tropic changes known as "stigmata." We may meet with various forms of hyperaesthesia in dreams; quite apart from the recovery of sight by those who have lost it wholly or in part (see below, Dreams of the Blind), we find that the powers of the senses may undergo an intensification, and, e.g., the power of appreciating music be enormously enhanced in persons usually indifferent to it. Mention must also be made of the experience of R. L. Stevenson, who tells in _Across the Plains_ how by self-suggestion he was able to secure from his dreams the motives of some of his best romances.

_Voluntary Action in Dreams._--Connected with dreams voluntarily influenced is the question of how far dreams once initiated are modifiable at the will of the dreamer. Some few observers, like F. W. H. Myers and Dr F. van Eeden, record that they can at longer or shorter intervals control their actions in their dreams, though usually to a less extent than their imagined actions in waking life. Dr van Eeden, for example, tells us that he has what he calls a "clear dream" once a month and is able to predetermine what he will do when he becomes aware that he is dreaming.

_Dreams of Children._--Opinions differ widely as to the age at which children begin to dream; G. Compayre maintains that dreaming has been observed in the fourth month, but reflex action is always a possible explanation of the observed facts. S. de Sanctis found that in boys of eleven only one out of eight said that he dreamt seldom, as against four out of seven at the age of six; but we cannot exclude the possibility that dreams were frequent but forgotten. If correct, the observation suggests that dreams appear comparatively late. Individual cases of dreaming, or possibly of waking hallucination, are known as early as the age of two and a half years; according to de Sanctis dreams occur before the fifth year, but are seldom remembered; as a rule the conscious dream age begins with the fourth year; speech or movement, however, in earlier years, though they may be attributed to reflex action, are more probably due to dreams.

_Dreams of the Old._--In normal individuals above the age of sixty-five de Sanctis found dreams were rare; atmospheric influences seem to be important elements in causing them; memory of them is weak; they are emotionally poor, and deal with long past scenes.

_Dreams of Adults._--Any attempt to record or influence our dreams may be complicated by (a) direct suggestion, leading to the production of the phenomena for which we are looking, and (b) indirect suggestion leading to the more lively recollection of dreams in general and of certain dreams in particular. Consequently it cannot be assumed that the facts thus ascertained represent the normal conditions. According to F. Heerwagen's statistics women sleep more lightly and dream more than men; the frequency of dreams is proportional to their vividness; women who dream sleep longer than those who do not; dreams tend to become less frequent with advancing age. The total number of remembered dreams varies considerably with different observers, some attaining an average of ten per night. The senses mainly active in dreams are, according to one set of experiments, vision in 60%, hearing in 5%, taste in 3%, and smell in 1.5%, where the dreamers had looked at coloured papers before falling asleep; when taste or smell had been stimulated, the visual dreams fell to about 50%, and the sense stimulated was active twice as often as it would otherwise be; dreams in which motion was a prominent feature were 10% of the former class, 14% and 18% of the two latter. Experiments by J. Mourly Vold show even more distinctly the influence of suggestion both as to the form, visual or otherwise, and the content (colours and forms of objects) of dreams. According to most observers dreams are most vivid and frequent between the ages of 20 and 25, but H. Maudsley puts the maximum between 30 and 35. De Sanctis got replies from 165 men and 55 women: the proportion between the sexes closely agrees with the results attained by Heerwagen and M. W. Calkins; 13% of men and 33% of women said they always dreamt, 27% and 45% often, 50% and 13% rarely, and the remainder (precisely the same percentage for men and women--9.09) either did not dream or did not remember that they dreamt. Nearly twice as many women as men had vivid dreams; in the matter of complication of the dream experiences the sexes are about equal; daily life supplies more material in the dreams of men; nearly twice as many women as men remember their dreams clearly, a fact which hangs together to some extent with the vividness of the dreams, though it by no means follows that a vivid dream is well remembered. There are great variations in the emotional character of dreams; some observers report twice as many unpleasant dreams as the reverse; in other cases the emotions seem to be absent; others again have none but pleasing dreams. Individual experience also varies very largely as to the time when most dreams are experienced; in some cases the great majority are subsequent to 6.30 A.M.; others find that quite half occur before 4.0 A.M.

_Dreams of the Neuropathic, Insane, Idiots, &c._--Much attention has been given to the dreams of hysterical subjects. It appears that their dreams are specially liable to exercise an influence over their waking life, perhaps because they do not distinguish them, any more than their waking hallucinations, from reality. P. Janet maintains that the cause of hysteria may be sought in a dream. The dreams of the hysterical have a tendency to recur. Epileptic subjects dream less than the hysterical, and their dreams are seldom of a terrifying nature; certain dreams seem to take the place of an epileptic attack. Dreaming seems to be rare in idiots. De Sanctis divides paranoiacs into three classes: (a) those with systematized delusions, (b) those with frequent hallucinations, and (c) degenerates;--the dreams of the first class resemble their delusions; the second class is distinguished by the complexity of its dreams; the third by their vividness, by their delusions of megalomania, and by their influence on daily life. Alcoholic subjects have vivid and terrifying dreams, characterized by the frequent appearance of animals in them, and delirium tremens may originate during sleep.

_Dreams of the Blind, Deaf, &c._--As regards visual dreams the blind fall into three classes--(1) those who are blind from birth or become blind before the age of five; (2) those who become blind at the "critical age" from five to seven; (3) those who become blind after the age of seven. The dreams of the first class are non-visual; but in the dreams of Helen Keller there are traces of a visual content; the second class sometimes has visual dreams; the third class does not differ from normal persons, though visual dreams may fade away after many years of blindness. In the case of the partially blind the clearness of vision in a dream exceeds that of normal life when the partial loss of sight occurred in the sixth or later years. The education of Helen Keller is interesting from another point of view; after losing the senses of sight and hearing in infancy she began her education at seven years and was able to articulate at eleven; it is recorded that she "talked" in her dreams soon after. This accords with the experience of normal individuals who acquire a foreign language. Her extraordinary memory enables her to recall faintly some traces of the sunlit period of her life, but they hardly affect her dreams, so far as can be judged. The dreams of the blind, according to the records of F. Hitschmann, present some peculiarities; animals as well as man speak; toothache and bodily pains are perceived as such; impersonal dreaming, taking the form of a drama or reading aloud, is found; and he had a strong tendency to reproduce or create verse.

_Dreams of Animals._--We are naturally reduced to inference in dealing with animals as with very young children; but various observations seem to show that dreams are common in older dogs, especially after hunting expeditions; in young dogs sleep seems to be quieter; dogs accustomed to the chase seem to dream more than other kinds.

_Dreams among the Non-European Peoples._--In the lower stages of culture the dream is regarded as no less real and its personages as no less objective than those of the ordinary waking life; this is due in the main to the habit of mind of such peoples (see ANIMISM), but possibly in some measure also to the occurrence of veridical dreams (see TELEPATHY). In either case the savage explanation is animistic, and animism is commonly assumed to have been developed very largely as a result of theorising dreams. Two explanations of a dream are found among the lower races: (1) that the soul of the dreamer goes out, and visits his friends, living or dead, his old haunts or unfamiliar scenes and so on; or (2) that the souls of the dead and others come to visit him, either of their own motion or at divine command. In either of the latter cases or at a higher stage of culture when the dream is regarded as god-sent, though no longer explained in terms of animism, it is often regarded as oracular (see ORACLE), the explanation being sometimes symbolical, sometimes simple.

There are two classes of dreams which have a special importance in the lower cultures: (1) the dream or vision of the initiation fast; and (2) the dream caused by the process known as incubation, which is often analogous to the initiation fast. In many parts of North America the individual Indian acquires a tutelary spirit, known as _manito_ or _nagual_, by his initiation dream or vision; the idea being perhaps that the spirit by the act of appearing shows its subjection to the will of the man. Similarly, the magician acquires his familiar in North America, Australia and elsewhere by dreaming of an animal. Incubation consists in retiring to sleep in a temple, sometimes on the top of a mountain or other unusual spot, in order to obtain a revelation through a dream. Fasting, continence and other observances are frequently prescribed as preliminaries. Certain classes of dreams have, especially in the middle ages, been attributed to the influence of evil spirits (see DEMONOLOGY).

_Classical and Medieval Views of Dreams._--Side by side with the prevalent animistic view of dreams we find in antiquity and among the semi-civilized attempts at philosophical or physiological explanations of dreams. Democritus, from whom the Epicureans derived their theory, held the cause of them to be the simulacra or phantasms of corporeal objects which are constantly floating about the atmosphere and attack the soul in sleep--a view hardly distinguishable from animism. Aristotle, however, refers them to the impressions left by objects seen with the eyes of the body; he further remarks on the exaggeration of slight stimuli when they are incorporated into a dream; a small sound becomes a noise like thunder. Plato, too, connects dreaming with the normal waking operations of the mind; Pliny, on the other hand, admits this only for dreams which take place after meals, the remainder being supernatural. Cicero, however, takes the view that they are simply natural occurrences no more and no less than the mental operations and sensations of the waking state. The pathological side of dreams attracted the notice of physicians. Hippocrates was disposed to admit that some dreams might be divine, but held that others were premonitory of diseased states of the body. Galen took the same view in some of his speculations.

Symbolical interpretations are combined with pathological no less than animistic interpretations of dreams; they are also extremely common among the lower classes in Europe at the present day, but in this case no consistent explanation of their importance for the divination of future events is usually discoverable. Among the Greeks Plato in the _Timaeus_ (ch. xlvi, xlvii) explains dreams as prophetic visions received by the lower appetitive soul through the liver; their interpretation requires intelligence. The Stoics seem to have held that dreams may be a divine revelation and more than one volume on the interpretation of dreams has come down to us, the most important being perhaps the [Greek: Oneirokritika] of Daldianus Artemidorus. We find parallels to this in a Mussulman work by Gabdorrachaman, translated by Pierre Vattier under the name of _Onirocrite mussulman_, and in the numerous books on the interpretation of dreams which circulate at the present day. In Siam dream books are found (_Intern. Archiv fur Anthr._ viii 150); one of the functions of the Australian medicine man is to decide how a dream is to be interpreted.

_Modern Views._--The doctrine of Descartes that existence depended upon thought naturally led his followers to maintain that the mind is always thinking and consequently that dreaming is continuous. Locke replied to this that men are not always conscious of dreaming, and it is hard to be conceived that the soul of the sleeping man should this moment be thinking, while the soul of the waking man cannot recollect in the next moment a jot of all those thoughts. That we always dream was maintained by Leibnitz, Kant, Sir W. Hamilton and others; the latter refutes the argument of Locke by the just observation that the somnambulist has certainly been conscious, but fails to recall the fact when he returns to the normal state.

It has been commonly held by metaphysicians that the nature of dreams is explained by the suspension of volition during sleep; Dugald Stewart asserts that it is not wholly dormant but loses its hold on the faculties, and he thus accounts for the incoherence of dreams and the apparent reality of dream images.

Cudworth, from the orderly sequence of dream combinations and their novelty, argues that the state arises, not from any "fortuitous dancings of the spirits," but from the "phantastical power of the soul." According to K. A. Scherner, dreaming is a decentralization of the movement of life; the ego becomes purely receptive and is merely the point around which the peripheral life plays in perfect freedom. Hobbes held that dreams all proceed from the agitation of the inward parts of a man's body, which, owing to their connexion with the brain, serve to keep the latter in motion. For Schopenhauer the cause of dreams is the stimulation of the brain by the internal regions of the organism through the sympathetic nervous system. These impressions the mind afterwards works up into quasi-realities by means of its forms of space, time, causality, &c.

DREDGE AND DREDGING. The word "dredge" is used in two senses. (1) From Mid. Eng. _dragie_, through Fr. _dragee_, from Gr. [Greek: tragemata], sweetmeats, it means a confection of sugar formed with seeds, bits of spice or medicinal agents. The word in this sense is obsolete, but survives in "dredger," a box with a perforated top used for sprinkling such a sugar-mixture, flour or other powdered substance. "Dredge" is also a local term for a mixed crop of oats and barley sown together ("maslin" or "meslin," cf. Fr. _dragee_), and in mining is applied to ore of a mixed value. (2) Connected with "drag," or at least derived from the same root, dredge or dredger is a mechanical appliance for collecting together and drawing to the surface ("dredging") objects and material from the beds of rivers or the bottom of the sea. In the following account the operations of dredging in this sense are discussed (1) as involved in hydraulic engineering, (2) in connexion with the work of the naturalist in marine biology.

1. HYDRAULIC ENGINEERING

Dredging is the name given by engineers to the process of excavating materials under water, raising them to the surface and depositing them in barges, or delivering them through a shoot, a longitudinal conveyor, or pipes, to the place where it is desired to deposit them. It has long been useful in works of marine and hydraulic engineering, and has been brought in modern times to a state of high perfection.

The employment of dredging plant and the selection of special appliances to be used in different localities and in varying circumstances require the exercise of sound judgment on the part of the engineer. In rivers and estuaries where the bottom is composed of light soils, and where the scour of the tide can be governed by training walls and other works constructed at reasonable expense, so as to keep the channel clear without dredging, it is manifest that dredging machinery with its large cost for working expenses and for annual upkeep should be as far as possible avoided. On the other hand, where the bottom consists of clay, rock or other hard substances, dredging must, in the first instance at any rate, be employed to deepen and widen the channel which it is sought to improve. In some instances, such as the river Mississippi, a deep channel has for many years been maintained by jetties, with occasional resort to dredging to preserve the required channel section and to hasten its enlargement. The bar of the river Mersey is 11 m. from land, and the cost of training works would be so great as to forbid their construction; but, by a capital expenditure of L120,000 and an annual expense of L20,000 for three years, the depth of water over the bar at low tide has been increased by dredging from 11 ft. to 27 ft., the channel being 1500 ft. wide.

_"Bag and Spoon" Dredger._--The first employment of machinery for dredging is, like the discovery of the canal lock, claimed by Holland and Italy, in both of which countries it is believed to have been in use before it was introduced into Britain. The Dutch, at an early period, used what is termed the "bag and spoon" dredger for cleansing their canals. The "spoon" consisted of a ring of iron about 2 ft. in diameter flattened and steeled for about a third of its circumference and having a bag of strong leather attached to it by leathern thongs. The ring and bag were fixed to a pole which was lowered to the bottom from the side of a barge moored in the canal or river. The "spoon" was then dragged along the bottom by a rope made fast to the iron ring actuated by a windlass placed at the other end of the barge, the pole being prevented from rising by a hitched rope which caused the "spoon" to penetrate the bottom and fill the bag. When the "spoon" reached the end of the barge where the windlass was placed, the winding was still continued, and the suspended rope being nearly perpendicular the "bag" was raised to the gunwale of the barge and the excavated material emptied into the barge. The "bag" was then hauled back to the opposite end to be lowered for another supply. This system is still in use, but is only adaptable to a limited depth of water and a soft bottom; it has been largely used in canals and frequently in the Thames. At the Fosdyke Canal in Lincolnshire 135,000 tons were raised in the manner described. According to J. J. Webster (_Proc. Inst. C. E._ vol. 89), the first application of steam power for dredging operations was to a "spoon & bag" dredger for cleansing Sunderland harbour, the engine being made by Messrs Boulton & Watt of Soho, Birmingham.

_Dredging by Bucket between Two Lighters._--Another plan of dredging, practised at an early period in rivers of considerable breadth, was to moor two barges, one on each side of the river. Between them was slung an iron dredging bucket, which was attached to both barges by chains wound on the barrels of a crab winch worked by six men in one barge and round a simple windlass worked by two men in the other barge. The bucket, being lowered at the side of the barge carrying the windlass, was drawn across the bottom of the river by the crab winch on the other barge; and having been raised and emptied, it was hauled across by the opposite windlass for repetition of the process. This process was in use in the River Tay until 1833.

_Bucket Ladder Dredgers._--The earliest record of a bucket ladder dredger is contained in the first paper of the first volume (1836) of the _Transactions_ of the Institution of Civil Engineers. This machine was brought into use at the Hull Docks about 1782. The bucket chain was driven by two horses working a horse-gear on the deck of the vessel. The buckets were constructed of 5/8 in. bars of iron spaced 1/8 in. apart, and were 4 ft. long, 13 in. deep, 12 in. wide at the mouth and about 6 in. wide at the bottom. This dredger raised about 30 tons per hour at the cost of 2-1/2d. per ton, which covered the wages of three men working the dredger, eight men working the lighters and the keep of three horses. A dredger of this kind and power would only work in ballast, mud or other soft material, but the machine was gradually improved and increased in capacity and power by different manufacturers until it became a very efficient machine in skilful hands, excavating and raising material from depths of 5 ft. to 60 ft. of water at a cost not very different from, and in many cases less than, that at which the same work could be performed on land. With the powerful dredgers now constructed, almost all materials, except solid rock or very large boulders, can be dredged with ease. Loose gravel is perhaps the most favourable material to work in, but a powerful dredger will readily break up and raise indurated beds of gravel, clay and boulders, and has even found its way through the surface of soft rock, though it will not penetrate very far into it. In some cases steel diggers alternating with the buckets on the bucket frame have been successfully employed. The construction of large steam dredgers is now carried on by many engineering firms. The main feature of the machine is the bucket ladder which is hung at the top end by eye straps to the frame of the vessel, and at the lower end by a chain reived in purchase blocks and connected to the hoisting gear, so that the ladder may be raised and lowered to suit the varying depths of water in which the dredger works. The upper tumbler for working the bucket chain is generally square or pentagonal in form and made of steel with loose steel wearing pieces securely bolted to it. The tumbler is securely keyed to the steel shaft which is connected by gearing and shafting to the steam engine, a friction block being inserted at a convenient point to prevent breakage should any hidden obstacle causing unusual strain be met with in the path of the buckets. The lower tumbler is similar in construction to the upper tumbler, but is usually pentagonal or hexagonal in shape. The buckets are generally made with steel backs to which the plating of the buckets is riveted; the cutting edge of the buckets consists of a strong steel bar suitably shaped and riveted to the body. The intermediate links are made of hammered iron or steel with removable steel bushes to take the wear of the connecting pins, which are also of steel. The hoisting gear may be driven either from the main engine by frictional gearing or by an independent set of engines. Six anchors and chains worked by powerful steam crabs are provided for regulating the position of the dredger in regard to its work.

_Barge-loading Dredgers_ used formerly to be provided with two ladders, one on each side of the vessel, or contained in wells formed in the vessel near each side. Two ladders were adopted, partly to permit the dredger to excavate the material close to a quay or wall, and partly to enable one ladder to work while the other was being repaired. Bucket ladder dredgers are now, however, generally constructed with one central ladder working in a well; frequently the bucket ladder projects at either the head or stern of the vessel, to enable it to cut its own way through a shoal or bank, a construction which has been found very useful. In one modification of this method the bucket ladder is supported upon a traversing frame which slides along the fixed framing of the dredger and moves the bucket ladder forward as soon as it has been sufficiently lowered to clear the end of the well. In places where a large quantity of dredging has to be done, a stationary dredger with three or four large hopper barges proves generally to be the most economical kind of plant. It has, however, the disadvantage of requiring large capital expenditure, while the dredger and its attendant barges take up an amount of space which is sometimes inconvenient where traffic is large and the navigable width narrow. The principal improvements made in barge-loading dredgers have been the increase in the size of the buckets and the strength of the dredging gear, the application of more economical engines for working the machinery, and the use of frictional gearing for driving the ladder-hoisting gear. It is very important that the main drive be fitted with the friction blocks or clutches before alluded to.
