Chapter II: Boats, Rafts, and Make-Shift Floats (4)

In many parts of the world, boats of almost any size are built without metal fastenings, and the Massoolah boat of Madras may be taken as a fair type of those which are sewn or laced together. It will be seen in our illustration, copied by permission from a model in the United Service Museum, that the bottom boards are flat and form an oval elongated and pointed at the ends, so that the side planks curve naturally to meet the stem and stern-post, and give the boat an easy sheer. They are sewn together with coir yarn (or cocoa-nut husk fibre), the stitches crossing over a wadding of coir or straw, which presses on the seam and prevents much leakage. They are very elastic and give to the shock as they take the ground in the surf, which runs sometimes nearly 16ft. high; they are from 30ft. to 35ft. long, 10ft. or 11ft. wide, and 7ft. or 8ft. in depth; they pull double banked, six oars on a side, made of long rough poles with oval pieces of board lashed on the ends; they are steered by an oar. Our illustration shows also the catamaran or log float, on which the natives will pass to and from the shore when no other craft, not even the Massoolah boat, would venture. It must be remembered, however, that the men are themselves nearly amphibious, and care as little for being washed off their rafts as so many frogs; while the letters or small parcels they carry are kept dry only by being worn in a kind of oil-cloth turban.

{Norwegian boats.}

We have seen very nice boats built in Norway with dowels instead of nails; they were clinker built, and the dowels were about 1/2in., or fully as thick as the planking. A number of rods, from 3ft. to 4ft. long, are planed up to the required size, and cut into lengths say, when two thicknesses of 1/2in. plank are to be clinched, to 1-1/2in., or, when the two planks and a timber of perhaps 1in. are to be fastened, to 2-1/2in., so that both ends may project a little beyond the wood they are to fasten; the dowel is then split at each end with a sharp chisel, taking care that the cut is made at right angles to the grain of the plank or rib, wedges are driven in, and the end, being slightly spread out by the use of the clinch hammer, is trimmed off not too close; the wedges should be all neatly cut with a fine saw, and by sawing them in breadths from a board, and then splitting them to the required size, labour may be greatly economised. The holes should be bored with a sharp centre-bit; and if the dowels fit tightly the wedges may be dispensed with, as the ends will spread sufficiently under the clinch hammer without breaking the grain.

In building, if any difficulty should be found in drawing down the end of the plank to the stem, it will be advisable, after having fitted it carefully, to slack up the centre, let the end come to its place, fasten it, and then again bend the plank downwards. In some boats, especially in the navy, the planks do not run fore and aft, but two thin layers are crossed over each other diagonally, and clinched together; this leaves the outside perfectly smooth, and is perhaps the strongest known method of boat building. In planing up the edges of planks, &c., it is absolutely necessary to have a vice of some kind, and nothing is better than a tree vice, unless you have a blacksmith's. Saw off a young tree from 6in. to 8in. thick, at about 3-1/2ft. from the ground; saw the stump down the middle as low as you can; bind the lower part tightly with thongs of raw hide to prevent its splitting, then insert wedges to open the upper part, put your planks in, withdraw the wedges, and it will hold tight enough. It is as well to cut the upper part of the opening sufficiently wide to admit an inch plank, as short pieces can easily be put in to fill up should you wish to hold a thinner one.

{Portable steel boat.}

We have already mentioned the principle on which Mr. E. D. Young's portable steel boat for the Livingstone Search Expedition was built; and although, as we then said, none but a skilled workman could hope to turn up the edges of a curved sheet of metal, we think the principle might be applied to a flat-bottomed boat by merely snipping the flanges at the turn of the bilge, and bending upward the sides at any convenient angle; by cutting these more and more diagonally from the centre, the boat might be tapered to each end--not, indeed, in a true curve, but in a succession of short straight lines, which would tolerably represent one.

The number of pieces composing the "Search"--the boat used in the expedition sent in quest of Dr. Livingstone--were as follows: Thirty-six side pieces of steel, each being a load for one man; the midship piece required 2; the stern piece, 3; the bow piece, 3; the mast, 2; the boom, 2; the sails, 2; chain cable, 6; anchor, 1; and the whole with provisions, luggage, &c., made up 180 loads.

Captain Faulkner, who, as a volunteer, accompanied Mr. Young on the Search Expedition, has determined on returning with a party of ardent hunters and explorers, and an engineer, to Lake Nyassa, and for this purpose an iron steamer has been built 50ft. long, 5-1/2ft. deep, and 11-1/2ft. broad. The little craft, appropriately named the "Faugh-a-ballagh," is composed of 75 sections, put together with 8000 screws, so that she may be carried, as was the "Search," past the rapids and cataracts of the Shire River.

{American life raft.}

The American life raft "Nonpareil," which recently made the voyage across the Atlantic, may be taken as a successful application of the tubular system. It will be seen that she was constructed of three parallel inflatable tubes, covered with stout canvas, connected by breadths of the same, and with a rectangular frame laid over all to support the masts and rudder fittings; but the sketch is introduced here also to show the use of the droge, by which the little craft may in effect be anchored in the open sea, or at least may have her drift effectually checked, while the sea itself is broken before it reaches her. The droge in the present instance is of canvas, stretched on a large hoop with four lines, so attached to its circumference that when the strain comes on it it stands vertically in the water, and opposes the resistance of its entire surface. The oars or mast, and sails of a boat, will also answer this purpose; and we have heard of one instance in which the imperilled crew added also a number of the skins of freshly-killed seals, the oil working out of which calmed the water for a considerable distance. It is necessary to watch the length of the sea, so that the boat may be veered as far from the droge or raft as it will serve to protect her against the breaking waves. We have heard the captain of a vessel say that he would never incur the risk of wearing in a gale, but would rather sacrifice some spar or piece of lumber to bring the ship's head to the wind. In doing this, the hawser would be carried round from the droge on the weather bow, under the bobstays and bowsprit rigging to the lee bow, and finally to the quarter; the droge would be thrown over, sufficient line paid out, and then held on to till the ship's head came to the wind; the strain would be then changed for a moment to the lee bow, and then to the quarter, whence it would be cut away as the ship fell off upon the other tack. A spar held by a hawser and bridle, with a stout sail bent to it--the clews, or lower corners, being weighted with shot, lead, or iron, to make them heavy--forms an excellent droge for a small craft to lie to under.

{Temporary repairs of vessels.}

Although this subject may seem almost beyond the province of our work, it is by no means improbable that explorers may have to turn their attention to it, or that shipwrecked crews, or dwellers on a lonely coast, may have to repair or build small craft for themselves. We have seen first-class waggons built by missionaries, and others have built vessels; and the reader may remember with advantage the description given by Ulysses of his laying down side by side ten or a dozen pine trees more or less smoothed off as a foundation on which to build his upper works.

During the progress of the North Australian Expedition, we were ascending the Victoria River with our little schooner, the "Tom Tough." There was little or no wind, and with the boat ahead towing and the lead going we were drifting up with a strong flood-tide, and the captain, elated by success, and anxious to make the most of his opportunity, kept going onward instead of prudently anchoring while the tide was still rising. In consequence of this, when the vessel touched the ground, there was no subsequent rise of water to float her off; indeed, it was remarked that the water began to fall while the tide was still running upward, and she was left at low water on the 27th of September, 1855, on a mud bank, with her bows uncomfortably propped up by a projecting rock.

On the 29th she floated; but the flood-tide was so nearly done, that we had no time to choose an anchorage, and the schooner grounding with the ebb, parted her chain cable and heeled over with the force of the tide till we could barely stand upon her decks.

Day after day the schooner drifted to and fro upon this sand-bank, sometimes moving a length or two, and sometimes only a few feet during a tide; the sand scoured out from beneath her bow and stern, leaving holes with 6ft. or more of water there, while hillocks accumulated under her in midship; and the sand seemed to travel so evenly with her, that the usual criterion--a hand lead, allowed to trail upon the ground--was of no service in enabling us to estimate the distance she had moved.

On the 10th of October the decks had rifted, the combings of the main hatch had started up, the starboard side between the masts was hogged up 18in., and at the turn of the bilge, where the floor timbers join the ribs, one of the planks had split for 15ft. or more, leaving spaces into which the flat hand might easily be passed.

We laid broad strips of blanket and sheepskin well tarred on the principal rents, and nailed thin planks over them (Fig. 8, p. 170), but in another day or two she was just as bad on the other side; her stern was peaked into the air, while her bows dipped about 7ft. into a hole, the water pouring out of the fresh rifted planking as the tide fell. The mainmast rose up through the partners, so that we were obliged to slack off the rigging, and it became a question whether the stanchion under the main hatch should be knocked away to prevent its bursting up the deck, or whether it should remain so that the strength of the deck might keep the bottom a little longer from breaking.

On the 25th we again floated, after nearly a month of straining to and fro upon the sand-banks, and drifted rather than navigated the vessel up to the camp we had established below Steep-head.

Captain Gourlay with his crew, and some of the expedition men, found suitable trees some little distance up the river at Timber Creek, which, however, after a rather exciting adventure with some wandering natives, acquired the name of Cut-Stick Creek instead. Two long heavy gum trees as straight as possible were selected, brought to the vessel, and laid as sister keelsons (Fig. 2) alongside the real one, which, as well as all the original framework, is marked Fig. 1 in our illustration. Three or four pair of heavy crooks, each representing the half of a floor timber (Fig. 3), were then laid on the inner skin, with the inner ends abutting on the sister keelson, and the outer reaching up above the junction of the ribs with the floor heads. Heavy riders (Fig. 4) were placed upon them crossing the three keelsons, and were secured by clamps (Fig. 5) made of the tires of our dray wheels, which we had no hope of being able to put to their proper use. Being now above the rise and fall of the tide we could not beach the vessel, and, therefore, the frame could only be bolted to the true sides above the water line (Fig. 6), but it was pressed down upon the bottom not only by its own weight but by stanchions (Fig. 7) between it and the deck beams.

The schooner being detained for repairs, it was decided to undertake an expedition to the Albert River in the long boat; and thus, by reaching Mr. Gregory in time to assure him that a vessel was coming, prevent his starting for the colony with insufficient supplies; Mr. George Phibbs, the overseer of the expedition, and Mr. Graham, the mate of the "Messenger," volunteering for the trip, we commenced our preparations. The boat was cleaned, repainted, the leaks stopped; and two inflatable tubes were made, each of them of one piece of canvas, 14ft. long, lined with waterproofed calico, folded so that the two sides should come together, a rope along the seam, with eyes turned in at the corners, to make it fast by, and, with one of the screw valves from our worn-out boat (p. 48), let into the after end, to receive the nozzle of the bellows. These we at first intended to stretch beneath the thwarts, inside, but eventually laced them outside each gunwale, where they were less in the way, and, when kept in a state of semi-inflation, projected sufficiently to prevent a great deal of the ripple of the sea washing into the boat, and this advantage we made the most of when we were fairly at sea, by fitting light bamboo stanchions forward, and securing the tubes to them, so as to make a kind of raised wash streak round the bows.

We left the vessel on the 23rd of October off New Year's Island, and at first had fine weather with good working breezes, but in a few days strong adverse gales came on. On the 2nd of November we worked all day clawing off a lee shore, the sea raging furiously over the shallow bottom; but our boat, though only 18ft. long and 6ft. beam, behaved well, and we weathered the rocks by less than a quarter of a mile after sunset. Darkness came on at once, and, as we dare not run in for shelter, we made the boat snug and hove to under foresail and mainsail all night. We ran through between the Crocodile islands, the crest of the short sea behind us foaming around our quarters, while our bowsprit was actually dipping in the next, and began to fear that we should have to pass the islands without finding a shelter, when Phibbs volunteered to swim ashore. We let go our carronade as an anchor, and ran in to the full length of the line; he sprang overboard, and with some difficulty reached the shore, where he soon found a quiet little nook to which he beckoned us to steer.

We will only add that on the 17th of November, after having sailed nearly 750 miles, we reached the mouth of the Albert River, in the Gulf of Carpentaria.

{Sails and their substitutes.}

We cannot dismiss the subject of boats without appending a few remarks on such simple forms of sails as are likely to be of service in such small craft as a traveller might possess, and we shall take, as the maximum, one of those swift and handy fore and aft schooners in which the Americans push their trade in all quarters of the world. Each lower mast and topmast would most likely be in one piece, combining great strength with neatness, and obviating the necessity for much staying. The bowsprit is also of a single piece; the sails are a jib from the foremast head to the bowsprit end, a forestaysail set to the stem head, a foresail and mainsail on gaffs made to lower when the sail is reefed or taken in; the foot of the mainsail is always extended by a boom, and that of the foresail sometimes; if they are laced to the boom, as in the yacht "America," which had booms even to the foot of her jibs, the sails sit flatter and better on a wind, but if they are not, there is the advantage of being able to reduce the sails without the trouble of reefing, by tricing up the foot; gaff topsails may be either jib-headed, like the fore, or on a gaff, like the main, in Fig. 1. The mainstay causes some little difficulty; if it goes from mast to mast, the tack and sheet of the fore gaff topsail must be passed over to leeward of it when the vessel goes about; if it leads down to the deck there must be two parts, one on each side the foresail, and the lee one ought to be slacked, and the weather one set up on each tack. If a foreyard, or rather a cross-jack, is carried, a flying squaresail, half the width of the yard, may be sent up on the weather side, and a topsail may be set in the same manner, the fore and aft sails supplying canvas enough on the lee side.

The cutter (No. 2) has a jib, a foresail on the stay, and a mainsail; the jib topsail runs with grummets on the topmast stay, but the halyards only reach the lowermast head; a lug-headed gaff topsail gives opportunity for a greater spread of canvas.

The boat (No. 3) is rigged with foresail and spritsail. An eye in the peak of the latter receives the upper point of the sprit, while the lower end is set into the eye of a snorter, a bight of rope passing round the mast and tightened chiefly by the strain of the sail upon it. Sometimes it is pushed up by hand while the sail shakes, so as to set it properly up, but it is better to have a small tackle as seen on page 171 to set it up with.

No. 4 has shoulder-of-mutton sails, the peaks of which are bent on to small taper yards which slide up and down on and abaft the lower masts like gunter topmasts; this facilitates the reefing of the sails, and also the setting of the jib from the foremast head.

No. 5 is a lugger, the yards are slung in the thirds, the shortest and thickest arm is forward, and the longest tapers aft; the foremost leach of the sail is very strongly roped, so that the tack holds down the forearm and elevates the peak. Sometimes in well-manned vessels the lugs are dipped so as to pass to leeward of the mast whenever they go about, and in this case the tack may be bowsed down considerably in front of the mast and a large sail carried; but in short-handed craft the tacks are brought down to the mast, and the foresail and mizen are set on one side and the mainsail on the other, and are not dipped. The after leach of the jib must be cut so as to go clear of the foreyard, the topmasts to slide abaft the lower masts; and there is always some difficulty in setting a fore topsail, as there must either be a double tack to pass the sail over the jib halyard in going about, or its fore leach must remain to leeward of it.

The lateen (No. 6) has triangular sails with very long taper yards, the head and fore leach becoming one; indeed, if there be any distinct fore leach, the sail becomes an ill-shaped lug, and not a lateen. The masts are somewhat short; sometimes mere stumps, but then the halyards and the tacks must be enormously strong to counterpoise the immense length of the yard.

The proa sail (Figs. 7 and 8, p. 173), a triangle spread upon two bamboos, hitched upon a stump mast in small boats, we have described at p. 135. No. 9 is a modification of it, by which a boat sets jib and mainsail in one, the angle formed by the yard and boom becomes more acute at each reef as indicated by the lines. It would be difficult, however, to work the boat without a small mizen to help her round in staying. No. 10 is the shoulder-of-mutton sail, set on a single taper yard or mast.

Palm leaves are sometimes used as sails; our sketch represents three or more cocoanut leaves, so woven together as to present a surface to receive the wind. Blankets and articles of clothing are used in emergencies. Oars are set up, and a boat will gather considerable way under them. Planks, the broader and flatter the better, are excellent substitutes, and may be trimmed at pleasure. It must not be forgotten that, however graceful in art and poetry the bellying canvas may be, the chief object of the sailmaker is to get it "to sit like a board."

{Reefing of sails from the sides.}

Sometimes when a sail is split, or otherwise rendered unserviceable, it is desirable to use another for a substitute without spoiling it by cutting. We remember reading of a vessel in which the topsail was split in a heavy gale; a spare foresail was got out and stout bands sewed on it, from the clews to the reef-band, diminishing upwards to the width the topsail head ought to be; eyelet holes were worked in, points or lacings inserted, and the sail, thus reduced, sent up to do duty as a topsail.

Captain (now Admiral Sir E.) Belcher, when in command of H.M.S. "Sulphur," made use of a very clever expedient for imparting motion to his vessel when the wind failed. He constructed a couple of bolts, with stout umbrella framework covered with canvas at their heads, and with their butts so thickened as to fit loosely into the bow guns. A line was attached to each butt, and one was given in charge to the port and the other to the starboard watch; the first was fired to a good distance ahead, and as soon as the line was hauled upon the frame expanded and opposed its full resistance, so that, as it could not be drawn backwards through the water, the vessel must begin to move. Before this was hauled in the next was fired, the ship would increase her rate of progress, and, the impetus being once acquired, she would "hold her way," so that eventually the men would have little more to do than gather in the slack of the line. No sailor likes the inaction of a calm, and besides this the captain had judged rightly in exciting the emulation of his men by giving one to each watch, and further stimulating it by an occasional glass of grog to the hardest working side, so that the cry of the port watch would be, "Haul away, and run her up to the umbrella before the starbowlines get theirs laid out," and _vice versâ_, till sometimes a speed of four knots an hour was obtained. Thus was the good ship hauled out of many a belt of calms, and brought into the region of the winds, which might be only a few miles distant, while other vessels not so provided might have lain becalmed for weeks; and not only this, but her position in a bay or anchorage could be shifted at pleasure, and she became almost independent of wind or extraneous assistance by this ingenious expedient.

Paddles worked by mill sails have been proposed; but of these it will be sufficient to remark that the power of the paddles to drive the vessel's head to wind will be less than that of the wind to drive her backward by the full amount of all that is expended in overcoming the friction of the machinery; in every other position the wind on the sails would do its work without the paddles.

{Hints in emergencies.}

A Prussian vessel, with the leaks gaining on her and her crew exhausted, was saved by lashing a spar across the mainmast, with one end projecting overboard with a barrel half full of water fast to it, so as to rise and fall with the sea. The pump brakes were made fast to the spar, and the vessel was thus kept afloat, while the crew were relieved from their labour.

A boat has been known to come ashore safe through a heavy sea by means of a handful of oil judiciously thrown over by one of the men whenever a wave threatened to break near her; and Captain Basil Hall relates how one of his boats was hove to all night under a droge of all her spars and sails and two or three seal skins, the oil of which working out calmed the water for a considerable distance.

Instances of this kind might be indefinitely multiplied; but we note only a few as suggestions. No amount that we could give would supply the want of presence of mind and the ready power of adapting the means at hand to the emergency.

Our space will not allow us to go into all the details of boat sailing, but we must find room for one or two general rules. In seeking to land through breakers, which must always be effected by the oars, wait just outside them till you find the heaviest roller coming in; then give way, and come in upon it, with your boat's bow all but overhanging its crest, and, as it lands, you jump out and haul your boat beyond the power of its reflux. Some crews are in the habit of giving two or three powerful strokes just before they reach the shore, and then pitching their oars simultaneously as far from them as possible, picking them up again when they have secured their boat. It is well, however, to know that there is no current to set the oars out to sea before doing this.

In coming off face the breakers boldly, but judiciously watch the smaller waves, and give her good way through them. Keep your boat's head on to the sea, and never let her take a breaker more than two points on either bow.

Trim the sails so that when brought to the wind the boat will very nearly steer herself, and she will attain her utmost speed. The action of the rudder has always a slightly-retarding influence, but if there is any want of balance let it be on the side of ardency or tendency to fly up in the wind, so that she may carry a little weather helm rather than want helping up by a lee one, and thus, in case of sudden squalls, the boat will, as if by instinct, obey the first touch of the lee helm, and, shaking the wind out of her sails, will right herself. The main sheet of an open boat should never be made fast, but held either by the steersman, or some one near him, in readiness to ease off. A squall seldom comes so suddenly that the first puff, if well watched, will not help the boat into the wind before the full strength comes; but on the coast of Australia we have known a squall come so suddenly through the dead calm of the night that it struck us at once like a blow from a sledge-hammer, and, though we had taken all the usual precautions, the sea was pouring like a jet-black cataract flecked with diamonds over 8ft. of the lee gunwale before the boat came to the wind; and we would say, therefore, if there is not an air to bring the boat's head up when you expect a squall, help her with the sweep of an oar into the best position to receive it.

If you want to carry on sail do not attempt to stiffen the boat by making all the crew sit to windward; for, should the mast break, as is not unlikely with the increased strain, nothing can prevent her capsizing; let them sit in the bottom. In the way of ballast, nothing can be better than bags nearly filled with fresh water. They will assume the form of any place you want to stow them in, and will not sink the boat if she should fill; in fact, being lighter than salt water, they would impart a trifling buoyancy.

{Temporary rudders.}

The loss of the rudder, an accident which is by no means so unfrequent at sea as may be imagined, involves also, for a time at least, the loss of control over the vessel's course. Even in the open sea this must be attended with considerable peril; but when it happens in the vicinity of rocks or shoals, and the vessel has not sea-room, the danger becomes appalling. The careful and vigilant trimming of the sails is the readiest means of regaining command of the vessel, and we believe the "Wager" was extricated from a most perilous position by this alone; but it is a work of immense labour, and harasses the crew severely. A stream cable payed out astern, and veered to either quarter, is sometimes used; or, if the accident should occur in moderate weather, by striking on a bar, the jolly boat with the plug out may be lowered and towed astern, but both these plans check the speed of the vessel, and are only useful when they can be made to impede one side more than the other; and that this is not the true principle of steering is known to every butcher's boy, who apologises for wearing but one spur by saying "if one side of his horse goes the other must." The rudder may be considered as a continuation of the keel, capable of moving on a hinge to an angle of 22-1/2° on either side, and when the vessel moves forward, and the helm, for instance, is put to port, the water impinging on the starboard side of the rudder is reflected from it at an equal square to that of its incidence, and the resulting force tends to drive the stern to port and incline the head to starboard. But as the force acts in the direction of a line midway between the angles of incidence and of reflection, it has also a retarding tendency, and if the helm were put over to an angle of 45° the greater part of the power would be expended in stopping rather than in steering the vessel. If a ship could be made so flexible as to be converted like a fish into the segment of a circle either way at pleasure, the very perfection of steering would be attained, and the rudder is merely the best imitation of this that can be devised.

Our illustration shows one expedient for the remedy of the misfortunes we have named. A warp or cable is faked down upon the deck in lengths equal to that of the required rudder, all the parts are then so closely pressed together that it resembles a board of the required breadth; it is then stiffened by longitudinal and cross bars, a weight is attached to the bottom, and a tiller projects aft, from the extremity of which the steering tackles (A) lead in over each quarter. When lowered into its place, the heel is confined to the stern-post by chains or hawsers leading to the gangway on either side, and in the present instance ropes are reeved through the gudgeons on the stern-post. Sometimes two parts of the cable are left longer than the rest to come up the rudder trunk and form the neck of the rudder, a short spar passed through the bight on deck serves to suspend the whole. Very frequently, however, when the rudder goes, the gudgeons, and perhaps also part of the stern-post, are carried away, and it then becomes necessary to devise some plan which shall supply their loss.

Several expedients are given in the _Nautical Magazine_ for 1836, and from these we extract two or three examples. A spar, such as the spanker-boom or jibboom, is first passed over the stern, secured to the centre of the taffrail by temporary "partners," and to the heel of the stern-post by stout guys leading forward to the gangways on either side; the gaff is then fitted on this, just as it would be on a mast, and one of the smallest and stoutest storm staysails is laced, with the head downwards, to the upright spar, and also to the gaff, the foot of the sail being cut off, if it be too large. It is then hauled down to the lower end by a halyard previously reeved, and the gaff, which should go a little below the surface of the water, is hoisted until the sail sits "as flat" as a board. If greater power is thought necessary, the outer end of the gaff can be sawn vertically down the centre, and boards clinched in, as shown in the sketch (Fig. 3); or either the sail or boards might be used separately. The ship is steered by guys leading from near the end of the gaff over each quarter. Sometimes the principle of the steering oar is adopted: a spar, with planks fastened on its outer end, is got over, and the foremost end is fitted to the stern by ring-bolts or lashings, so as to allow it to work freely without too much play. The outer end is kept down either by a lower guy or by a piece of pig ballast or other weight; and if a topping-lift be attached, leading to a boom over the stern and thence to the mizen topmast-head, the oar may be lifted out of the water when one stroke has been completed, carried back again to the other side, and thus bring the ship's head round by a succession of sweeps.

Sometimes it is necessary to make a temporary stern-post, and the spare lower cap (which, however, we may remark, is generally stowed away where it is least likely to be found on an emergency) can be fitted on this by enlarging the masthead hole and securing it, as before, by lower guys. A topmast, with its heel upwards, may be passed down through it, and such additional spars or planking bolted on as will give the needful increase of breadth. The surface should be as smooth as circumstances permit, so that the water may glance off readily; the fid-hole will then receive the tiller, but the spar must be well banded or lashed round to prevent its splitting with the strain, or perhaps breaking off where the sheave-hole weakens it.

{Scarfing or fishing of broken spars.}

The captain of our battered little vessel had always some rough and ready expedient at his finger-ends. When one of the iron davits of the quarter boat was bent by a collision, he extemporised a forge with some pig ballast, on deck, and, though the planks beneath were somewhat scorched, he rendered the davit again effective. Once, when running before the wind, the mainsail jibed in consequence of careless steering, and the boom, being fastened by a "lazy guy," a slovenly shift a little too common among us, broke short off; however, a good stout plank was found, cut into four pieces, which were laid round the fractured part so as to inclose it in a kind of packing-case, of which the four sides did not meet at their edges; wooldings of rope were passed round at intervals and tightened by driving in wedges, and the boom, though somewhat clumsy, was again fit for duty. (See illustration.)

If a spar, with both ends alike, breaks at either end, a very neat and effective scarf may be made by sawing it down the centre and reversing the two parts, end for end, so that the fracture in one half may come against the unbroken part of the other, as in our sketch (p. 181). If the fracture is long, there may be no need for that unsightly appendage called a fish, and, even if it is short, a very small one will serve the purpose.

If a mast breaks, much above the deck, it may be again used, with little or no diminution of its strength, by reversing it, and stepping what used to be the masthead upon the keelson, so that the fractured part may come below the deck, while that which was the heel is shaped and fitted to become the head. It will be evident from the sketches we give that in a ship with a very deep hold, where very nearly half the mast is below the deck, this plan is more likely to be of service than in a shallow one, where the part below bears but a small proportion to that above.

{Kites.}

As a substitute or as an auxiliary to the common sails, or as a means of sending up a signal or effecting communication between a ship and a lee shore, a kite of sufficient power would frequently be useful.

Every voyager knows how frequently all the lower and larger sails of a vessel are becalmed, the uppermost and smallest catching only a gentle air, while at a little height above them the wind, as indicated by the fleecy clouds, may be blowing much more briskly.

In this case, when even the flying kites, as the upper sails are figuratively called, have become useless, real kites flying at a sufficient elevation would do good service; and even though the wind might not be fair, still so long as it was a little abaft the beam the vessel might be steered to her course. One thing must be kept in mind, and that is, that when it has once fallen calm below the kites cannot be raised to the breeze that is blowing above, therefore it would be well either to send them up before the breeze fails, or at least to send up in preparation a small one, to the line of which the larger could be hitched, and jerked clear when it had been carried to a sufficient altitude.

A kite of 12ft. in height spreads about 50ft. square of canvas, and will pull, in a fresh breeze, with a strength of about 200lb., if the height were doubled the strength would, of course, be fourfold; and as it would act as a lifting or buoyant instead of a depressing sail, the only risk in "carrying on" would be the parting of the line connecting it with the vessel; on this account it would be the best possible form of sail to rig in an open and over-crowded boat when leaving a wreck, for its tendency would be to lift the bows over the seas instead of depressing them. And even if a man about to risk the passage by swimming from a stranded ship to a lee shore could send up a small kite, such as he could make with a cotton shirt, a couple of sticks, and a few fathoms of fishing line, it would most likely buoy him over the crests of the breakers in which he would otherwise be overwhelmed. But the greatest objection to the general use of the kite is, that in the usual mode of flying we have no command of it except that of letting it go higher or hauling it in at the risk of breaking the line; this has been met by a very ingenious invention, and although it is patented, we think that we may do the public some service, and Mr. Pocock, the patentee, no harm, by describing it.

The common form of kite is best. The standard is made into two or three equal lengths, connected either by fishing-rod, by tent-pole, or by parasol joints; the wings have hinges at the head of the standard, and, if large, joints in each pinion. The flight band consists of two lines, the uppermost of which has an eye upon it through which the lower, called the brace line, reeves, and both come down to the hand of the conductor, and by these the deviation of the standard from the perpendicular is controlled. By hauling on the brace line the surface is opposed fairly to the full strength of the wind (Fig. 1); by slackening it the kite floats more horizontally, allowing the wind to pass gently beneath it, so that even in the strongest gale the power may be regulated at pleasure (Fig. 3). The power may be increased by backing the first with a second kite as in Fig. 2, all the lines of the second kite being made fast to their corresponding places on the first, so that both assume the same relative position in all cases. Two smaller lines from the wings, also passing through eyes on the upper line, act as braces by which to trim the kite upon a wind; and it appears from a diagram given by the inventor that a vessel braced sharp up will lie within about five and a half points of the wind, or as close as most vessels can with their usual sails, and, therefore, may turn to windward. With a kite the operation of tacking would be very easy. Even should the boat not answer her helm, the kite line taken aft would bring her head up to the wind, and, being carried round on the other quarter, and again forward to its proper place, would help her to her proper course; and in manoeuvring the absence of masts would be an advantage rather than not. A carriage with the fore wheels capable of being turned by a tiller would also turn to windward, and the draught power might be increased at pleasure by backing one kite with another, the connecting lines all being fastened in their proper places, as in the illustration (p. 183), so that whatever change of position was imparted to the lowermost kite might be also assumed by all that were harnessed to it.

Signals by day or night might be sent up with great facility by hitching the halyard block upon any part of the kite line, when the flags or lanterns might be sent far above any spars or sails that could obstruct the view of them. In case of shipwreck, even a common kite extemporised with the roughest materials would very generally be useful.

When the ship is on a lee shore, a common kite, flown from on board, could not fail to bring a line to land, and, with this communication once established, all hands could probably be saved. Their own boat might be veered ashore, or the men sling themselves with grummets and warp themselves hand over hand; or if passengers are on board, a cot or hammock, slung to notched blocks running on a hawser with a line to haul it back to the vessel, and one to bring it again towards the shore, might be employed.

But with kites rigged as we have described, there would have been a greater chance of safety, for they may be braced to fly three and a half points either way from the direction of the wind, and if they are employed to carry a grapnel or small kedge, they may be braced and veered within a limit of seven points of the compass towards a suitable spot; may be lowered gradually by the slacking of the brace line, and, if the hold is not good, again elevated by hauling it in, to drop the anchor in a more suitable spot.

In our full-page illustration the extemporised kite is not so completely rigged, but the flight line is led through a block, so that the wrecked crew could make fast to one end a stronger line; and, having hauled that through, could next bend on a sufficiently stout hawser.

The inventor states that he has travelled in a carriage, at twenty miles per hour; that a boat so drawn outsailed the speediest vessels of the usual rig; that a lady ascended to a height of a hundred yards; and that his son, with a 30ft. kite, scaled a cliff 200ft. high. Tho main and brace line of a kite of this size were 1/2in. in diameter, the braces (proper) were somewhat smaller. The discovery that a statue once stood on Pompey's Pillar was made by some merchant captains who ascended it by means of a line carried over by a kite.

{Weather signs.}

The canoe or boat voyager should at all times pay particular attention to the instructions which foretell the approach of storms; these are not at all times so unmistakable as to enable him to surely count on the kind of day or night which he has to pass through; still, the remarks of the late Admiral Fitzroy, published by the Board of Trade, are of much practical value:

"Whether clear or cloudy, a rosy sky at sunset presages fine weather; a red sky in the morning, bad weather, or much wind (perhaps rain); a grey sky in the morning, fine weather; a high dawn, wind; a low dawn, fair weather. Soft-looking or delicate clouds foretell fine weather, with moderate or light breezes; hard-edged oily-looking clouds, wind. A dark, gloomy blue sky is windy; but a light, bright blue sky indicates fine weather. Generally, the softer the clouds look, the less wind (but, perhaps, more rain) may be expected; and the harder, more 'greasy,' rolled, tufted, or ragged, the stronger the coming wind will prove. Also, a bright yellow sky at sunset presages wind; a pale yellow, wet; and thus, by the prevalence of red, yellow, or grey tints, the coming weather may be foretold very nearly, indeed, if aided by instruments, almost exactly. Small inky-looking clouds foretell rain; light scud-clouds driving across heavy masses show wind and rain; but, if alone, may indicate wind only. High upper clouds crossing the sun, moon, or stars, in a direction different from that of the lower clouds, or the wind then felt below, foretell a change of wind. When sea-birds fly out early, and far to seaward, moderate wind and fair weather may be expected; when they hang about the land, or over it, sometimes flying inland, expect a strong wind with stormy weather. There are other signs of a coming change in the weather known less generally than may be desirable, and, therefore, worth notice; such as when birds of long flight, rooks, swallows, or others, hang about home, or fly up and down or low--rain or wind may be expected. Also, when animals seek sheltered places, instead of spreading over their usual range; when pigs carry straw to their sties; when smoke from chimneys does not ascend readily (or straight upwards during calm), an unfavourable change is probable. Dew is an indication of fine weather: so is fog. Neither of these two formations occur under an overcast sky, or when there is much wind. One sees fog occasionally rolled away, as it were, by wind, but seldom or never formed while it is blowing."

{Waterproofing.}

The traveller will not unfrequently wish to render sailcloth, duck, calico, and other materials water-proof; few handy methods surpass that of the Chinese. They proceed as follows: to every ounce of melted white wax is added one quart of spirits of turpentine. The mixture must be stirred with a stick until quite cold, when the material to be treated is thoroughly dipped, allowed to drain out, and then finally hung by the corners in a current of air to dry. In making common tarpaulins it is well to soak the canvas thoroughly in sea-water before laying on the dressing, and as the water evaporates the tar penetrates the fabric. In Africa we used the acrid milky juice of the _Euphorbium_, mixed with a little boiled oil, on calico. It was very flexible, and perfectly protected a common open packing-case, with books and papers, on the deck of the vessel from the Cape to London. Boiled linseed oil, when allowed to soak into linen or cotton cloth, much increases its power of resisting the action of water.

{The deep-water glass.}

To those who are engaged in boat expeditions, researches along the sea-coast, or lake investigations, it is of the greatest importance to be able to see far down into the depths below; as, for example, for the recovery of sunken seals, which often go to the bottom like lead when struck dead by a shot, the examination of rocks, and the detection of lost objects. The late Mr. Wheelwright gives such a thoroughly practical account of his deep-water glass that we insert it in his own words: "I have had a little experience myself in seal-shooting off our north-west coast, and when I first began I had the mortification of seeing many a seal which I had shot stone dead go down like a plummet, and we lost him. But afterwards we used a seal-glass, a kind of machine very similar to a small hand-churn, like a bucket, about one yard high, tapering towards the top, about 9in. wide at the top and 18in. at the bottom. Of course the top was open, and in the middle of the bottom was fitted a square piece of glass (I believe common window glass). As soon as a seal sunk dead, we cast over a small buoy, kept in its place by a grapnel, as near the spot where the seal sank as possible, and then we examined the bottom after this fashion: We sunk the glass over the boat's side (just where we fancied the dead seal lay) into the water, within about two inches of the top (glass downwards), and by steadily looking down through the little glass window we could distinctly see the bottom of the sea and what lay on it. As soon as we saw the dead seal we hooked him up with a line and a drag. I don't know what is the greatest depth of water in which such a glass is available, and it is now some time since I used one; but I am sure I have often seen a dead seal lying in eight or ten fathoms; and just round the rocks where we shot the seals the water was never very deep, but still we rarely could see the bottom with the naked eye. I do not believe the glass at all has any magnifying properties, but I suppose the focus of vision is better concentrated below the surface of the waves in the comparatively still water. I was at this time living with one of the Customs' officers on the coast, who often used such a glass with great success in finding kegs that were sunk by smugglers off this coast.

{Treatment of the apparently drowned.}

Our remarks and directions concerning the various means which may be had recourse to for traversing rivers, lakes, and the sea would be incomplete without instructions for the restoration of the apparently drowned. None that can be drawn up are more perfect than those given by the authority of the Royal Lifeboat Institution, which were published, with some of the following remarks, in the _Field_ newspaper some short time since:--"Hanging the body up by the heels to drain out the water which is supposed to have been swallowed, is not one of the least injurious of the popular expedients in cases of suspended animation, and it is, in itself, sufficient to keep up the engorgement of the brain, which is one of the chief dangers to be apprehended. So, also, warm baths, tobacco smoke, and other depressing influences, should be strictly prohibited; and also that horrible practice of rolling the body over and over, which is so frequently adopted by those who are ignorant of its effects. The Royal National Lifeboat Institution and Humane Society constantly circulate printed papers containing cautions against the adoption of these expedients; but, unfortunately, they are seldom to be met with when they are wanted, and, on that account, we venture to impress upon our readers the importance of making themselves intimately acquainted not only with the objectionable practices to which we have alluded, but also with the methods which scientific men are agreed upon as those most likely to restore the circulation and respiration.
