Chapter XVI (3)

"The plant forms a stem about eighteen inches high, covered with
long leathery leaves in two ranks, like _Venda tricolor_ and its
allies; but they have a much more beautiful appearance, owing to a
drooping habit, and a delicate bloom which clothes their surface.
From the axils of the uppermost of these leaves appear short stiff
flower-stalks, each bearing three and sometimes five flowers,
extending seven inches in breadth and the same in height. They are
furnished with a firm, curved, tapering, tail-like spur, about
fourteen inches long. When first open, the flower is slightly tinged
with green except the tip, which is almost pure white; after a short
time the green disappears, and the whole surface acquires the
softest waxy texture and perfect whiteness. In this condition they
remain, preserving all their delicate beauty, for more than five
weeks. Even before they expand, the greenish buds, which are three
inches long, have a very noble appearance."

To the scientific naturalist few subjects are more full of deep interest than the question of the geographical distribution of animals. Dr. Sclater, the active secretary of the Zoological Society of London, has contributed an instructive paper, "On the Mammals of Madagascar," to the second, number {196} of the "Quarterly Journal of Science," from which we gather the following facts: As a general rule, it is found that the faunae and florae of such countries as are most nearly contiguous do most nearly resemble one another, while, on the other hand, those tracts of land which are furthest asunder are inhabited by most different forms of animal and vegetable life. Now, Madagascar, with the Mascarene islands, is a strange exception to the rule; for the forms of mammalia which are found in these islands are very different from the forms which occur in the contiguous coast of Africa, although the channel between Madagascar and the continent is in one place not more than 200 miles: "The numerous mammals of the orders Ruminantia, Pachydermata, and Proboscidea, so characteristic of the Ethiopian fauna, are entirely absent from Madagascar. The same is the case with the larger species of carnivora which are found throughout the African continent, but do not extend into Madagascar. Again, the highly organized types of Quadrumana which prevail in the forests of the mainland are utterly wanting in the neighboring island; their place being there occupied by several genera of the inferior family of _Lemurs_," Dr. Sclater shows that this anomaly is not confined to the orders already enumerated, but that similar irregularities prevail to a greater or lesser extent in every part of the mammalian series, and that, in short, the anomalies presented to us of the forms of life prevalent in the island of Madagascar "are so striking that claims have been put forward in its favor to be considered as a distinct primary geographical region of the earth." Dr. Sclater also draws attention to the very curious fact, "quite unparalleled, as far as is hitherto known, in any other fauna, that nearly two-thirds of the whole number of known species of the mammals of this island are members of one peculiar group of Quadrumana." The family of _Lemuridae_ contains no less than eight generic types, all different from those found in Africa and India, although this group is also represented in Africa by the abnormal form _Perodicticus_, and in India by _Nycticebus_ and _Loris_, two allied genera. The celebrated Aye Aye (_Chiromys Madagascariensis_), a specimen of which anomalous animal is at present in the new monkey-house in the Zoological Society's Gardens, Regent's Park, is considered by Prof. Owen to be more nearly allied to some of the African Galagos than to any other form of animal. Of insectivora, the genera _Centetes, Ericulus_, and _Echinogale_, small animals resembling hedge-hogs in outward appearance, are thought to be most nearly allied to an American genus. From the anomalies in the mammalian fauna of this island. Dr. Sclater arrives at the following deductions, which, however, as they are based upon the hypothesis of the derivative origin of species, cannot at present be deemed altogether conclusive:

"1. Madagascar has never been connected with Africa, _as it at
present exists_. This would seem probable from the absence of
certain all-pervading Ethiopian types in Madagascar, such as
_Antelope, Hippopotamus Felis_, etc. But, on the other hand, the
presence of _Lemurs_ in Africa renders it certain that Africa as it
at present exists, contains land that once formed part of
Madagascar.

"2. Madagascar and the Mascarene islands (which are universally
acknowledged to belong to the same category) must have remained for
a long epoch separated from every other part of the globe, in order
to have acquired the many peculiarities now exhibited in their
mammal fauna--_e.g._, _Lemur, Chiromys, Eupleres, Centetes,_
etc.--to be elaborated by the gradual modification of pre-existing
forms.

"3. Some land-connection must have existed in former ages between
Madagascar and India, whereon the original stock, whence the present
Lemuridae of Africa, Madagascar, and India, are descended,
flourished.

{197}

"4. It must be likewise allowed that some sort of connection must
also have existed between Madagascar and land which now forms part
of the new world--in order to permit the derivation of the
_Centetinae_ from a common stock with the _Solenodon_, and to
account for the fact that the Lemuridae, as a body, are certainly
more nearly allied to the weaker forms of American monkeys than to
any of the Simiidae of the old world.

"The anomalies of the mammal fauna of Madagascar can best be
explained by supposing that, anterior to the existence of Africa in
its present shape, a large continent occupied parts of the Atlantic
and Indian oceans, stretching out toward (what is now) America on
the west, and to India and its islands on the east; that this
continent was broken up into islands, of which some became
amalgamated with the present continent of Africa, and some possibly
with what is now Asia--and that in Madagascar and the Mascarene
islands we have existing relics of this great continent."

We fain would have lingered on the natural products of this interesting island, to drink of the refreshing liquid furnished by the traveller-tree, and to admire the sago palms and other vegetable forms, but space forbids our dwelling longer on the natural productions of the tropics. [Footnote 30] We could have spoken of the aspects of tropical nature as it appears in Borneo, Java, Sumatra, and other islands of the Pacific ocean, but we must stop. We ought not, however, to conclude these gleanings without a brief notice of Dr. Hartwig's popular book, whose title we have placed at the head of this article. There are those who look with contempt on popular science of all kinds, and regard with undisguised aversion such compilations as the one before us. We do not share these feelings in the least degree; on the contrary, we welcome most heartily such introductions to the study of natural history. True, they may be sometimes of little scientific value, but they are very useful stepping-stones to something more solid. They are more especially intended for the young, but those of mature years may derive much profit by a perusal of many of these works, and even the naturalist may read them with pleasure and instruction. The numerous beautifully illustrated and carefully compiled works on natural history, such as the book before us, together with "The Sea and its Living Wonders," by the same writer, with Routledge's admirable "Natural History," and several of the Christian Knowledge Society's publications, which have appeared within the last few years, are an encouraging sign of the growing interest which the rising generation takes in the study of the great Creator's works, and we heartily wish them "God-speed."

[Footnote 30: In our own territory of the Seychelles Islands, 4° to
5° S., 300 miles N. E. of the great island Just alluded to, we see
one of the strangest of vegetable productions, the double cocoa-nut,
or Lodoicea, which was fully described by Mr. Ward in the "Journal
of the Linnean Society, 1864:" "The shortest period before the tree
puts forth its buds is 30 years, and 100 years must elapse before it
attains its full growth. One plant in the garden at Government
House, planted 15 years ago, is quite in its infancy, about 16 feet
in height, but with no stem yet visible, the long leaves shooting
from, the earth like the Traveler's Palm (_Urania specioea_), and
much resembling it in shape, but much larger. Unlike the cocoa-nut
trees, which bend to every gale and are never quite straight, the
coco-de-mer trees are as upright as iron pillars. At the ago of 30
the trees first put forth blossoms. The female tree alone produces
the nut, and is 6 feet shorter than the male, which attains a height
of 100 feet. From fructification to full maturity a period of nearly
10 years elapses." But the remarkable point is the arrangement of
the roots, unlike any other tree. "The base of the trunk is of a
bulbous form, and this bulb fits into a natural bowl or socket about
2-1/2 feet in diameter and 1-1/2 foot in depth, narrowing to the
bottom. This bowl is pierced with hundreds of small oval holes about
the size of thimbles, with hollow tubes corresponding on the
outside, through which the roots penetrate the ground on all sides,
never, however, becoming attached to the bowl, their partial
elasticity affording an almost imperceptible, but very necessary
_play_ to the parent stem when struggling against the force of
violent gales. This bowl is of the same substance as the shell of
the nut, only much thicker. As far as can be ascertained, it never
rots or wears out. It has been found quite perfect and entire in
every respect 60 years after the tree has been cut down. At Curiense
many sockets are still remaining which are known to have belonged to
trees cut down by the first settlers in the Island (1742)." One of
these sockets is to be seen in the Museum of woods at Kew.]

From Chamber's Journal.

WINTER SIGNS.

Links upon the forehead come--
Strokes alike of time and grief,
Branches from the heart beneath
That will never bear a leaf.

Come the summer, come the spring,
Still they keep their wintry hue;
Deepening, stretching o'er the brow.
Shadows lift them into view.

Straight and crooked, right and left.
On the strong and on the weak--
Upward to the hoary head.
Downward to the hollow cheek.

Shadows from the life within,
Tarrying ere they pass away,
Plant these stems of sorrow there,
Growing in the night and day.

Light that fills the eye afresh
From some inward moving grace,
Casting from it, as a sun.
Quiet rays upon the face--

Makes these ruts of time appear
Winding, widening in their space,
Drawing loving eyes and thoughts
All their history to trace.

Whilst upheaved by a smile,
Radiant in the breast of light,
These eternal scores of grief
Tell of many an inner night.

Stories come up from their roots.
Half unfolded in their course,
Showing how a hundred pangs
Long ago became their source.
