There, to within a recent date, might be seen the bones of fourteen great green turtle side by side in a row. At first glance the scene seems a sanctified death-place for the species, until you are informed that a visitor to the isle, astonished at the number of turtle on the beach, and eager to secure an abundance of fresh meat, turned over fourteen, intending to call again for them. Circumstances prevented him from re-visiting the place, and the turtle, being unable to right themselves, perished.
Personal observation and inquiries from many men whose lives may be said to be spent among turtle on the Barrier Reef convince me that blacks never venture to get astride a turtle in the water. One more daring and agile may seize a turtle, and by throwing his weight aft cause the head to tilt out of the water. The turtle then strikes out frantically with its flippers, but the boy so counterbalances it that the head is kept above the surface continuously, until the turtle becoming exhausted is guided into shallow water or alongside a boat, where it is secured with the help of others. Boys who accomplish this feat are few and far between, though it is by no means uncommon for a turtle to be seized while in the water and overturned, in which position it is helpless. A turtle detected in shallow water falls a comparatively easy prey, for on being hustled it soon loses heart and endeavours to hide its head, ostrich-like, when it is easily captured. None unacquainted with the skill with which the creature can spar with its flippers, and the effectiveness of these flippers, when used as weapons of defence, should venture to grip a turtle in its natural element.
Another species, stated to have a circumscribed habitat, has a steep dome-shaped back, resembling at a casual glance a seamless metal casting, with the edges abruptly turned up. The head is large, the eyes deeply embedded in their sockets, and the animal has the power of protruding and withdrawing the head much more extensively developed than usual. The "death's head" staring from beneath the dome-shaped back gives to the animal a most gruesome aspect. These details are supplied by the master of a beche-de-mer schooner, to whom all the nooks and corners of the Great Barrier Reef and of the other Coral Sea beyond, from New Guinea to New Caledonia, are familiar. He says that the species, as far as his observation goes, is confined to the neighbourhood of one group of islands. To others this is known as the "bastard tortoiseshell." The back is not actually seamless, but age causes the plates to cohere so closely as to present that appearance.
THE MERMAID OF TO-DAY
Dugong (HALICORE AUSTRALIS) still frequent these waters. The rapacity of the blacks is a rapidly diminishing factor in their extermination, and the rushing to and fro of steamers, which it was thought would scare away those which remain, is becoming too familiar to be fearsome. Even in the narrow limits of Hinchinbrook Channel, through which the passing of steamers is of everyday occurrence, they still exist, though not in such numbers as in the early days. It would seem that the waters within the Great Barrier Reef may long continue one of the last resorts of this strange, uncouth, paradoxical mammal.
Half hippopotamus, half seal, yet in no way related to either, something between a pachyderm and cetacean, the dugong is a herbivorous marine mammal, commonly known as "the sea cow," because of its resemblance in some particulars to that useful domesticated animal. It grazes on marine grass (POSIDONIA AUSTRALIS), parts of the flesh very closely resemble beef, and post-mortem examination reveals internal structure similar in most details to those of its namesake. But, unlike the cow, the dugong has two pectoral mammae instead of an abdominal udder, and like the whale is unable to turn its head, the vertebrae of the neck being, if not fused into one mass, at least compressed into a small space.
In form it resembles a seal, the body tapering from the middle to the fish-like, bi-lobed tail. As with the whale, the flippers or arms do not contribute any considerable means of locomotion, but are used, in the case of the female at least, for grasping the young. When the mother is nursing her child, holding it to her breasts, she is careful as she rises to breathe, that it, too, may obtain a gulp of fresh air, and the two heads emerging together present a strangely human aspect. Traces of elementary hind legs are to be found in some small bones lying loosely in the flesh. The skull is singularly formed, the upper jaw being bent over the lower. The huge pendulous, rubber-like under lip, so studded with coarse, sharp bristles as to be known as the brush, seems a development of the under lip of the horse, and is a perfect implement for the gathering of slimy grass.
To further detail the paradoxes of the dugong, it may be said that some of the teeth resemble those of an elephant; that the males have ivory tusks and of ivory their bones are made; that parts of the flesh may hardly be distinguished from veal and other parts from fine young pork. The freshly flayed hide is fully half an inch thick, and when cured and dried resembles horn in consistency.
Reddish grey, sometimes almost olive green in colour, with white blotches and sparse, coarse bristles, the animal has no comeliness, and yet when a herd frolics in the water, rising in unison with graceful undulatory movements for air, and the sunlight flashes in helioscopic rays from wet backs, the spectacle is rare and fine. Rolling and lurching along, gambolling like good-humoured, contented children, the herd moves leisurely to and from favourite feeding-grounds, occasionally splashing mightily with powerful tails to make fountains of illuminated spray—great, unreflecting, sportful water-babes. Admiration is enhanced as one learns of the affection of the dugong for its young and its love for the companionship of its fellows. When one of a pair is killed, the other haunts the locality for days. Its suspirations seem sighs, and its presence melancholy proof of the reality of its bereavement.
For some time after birth the young is carried under one or other of the flippers, the dam hugging it affectionately to her side.
