The entire surface of this translucent and almost colourless body is studded with minute specks of rust-red, and with still smaller ones of opaque pale yellow, which are visible only with the aid of a lens. Nothing can be more sand-like than this aggregation of red and yellow dots, and surely we must look upon it, in conjunction with the habits of the little feeble fish, as a special provision for its safety, ordained by Him whose tender mercies are over all His works. The eyes are very prominent, and set in very thick and dark orbits; the pupil is surrounded by a crimson iris. Great size and prominence of the eyes is quite characteristic of the fishes of this family. It may be that their habitual residence in the shallows exposes them peculiarly to the attacks of enemies; and the size of the eye may be connected with a greater power or quickness of sight, indicating a proportionate development of the optic nerve. But this is only a conjecture.

The pectorals, as usual, are large, but quite colourless, and hence can scarcely be discerned, or only like a film of clear talc. The two dorsals are ordinarily carried, when at rest, depressed quite down to the back, but are elevated in swimming. The tail is crossed vertically by bands of red dots. Like most of the sand-loving creatures, the Freckled Goby does not long survive captivity in a tank. Perhaps, however, this may be because our aquariums are not specially arranged with a view to their instincts. A very wide shallow vessel, with a bottom of sand, and a piece or two of rough rock for shadow, stocked with Freckled Gobies, Weavers, Sand-launces, Shrimps, Venuses, Naticas, etc., might do well. But these will not do with an ordinary collection of rock-loving things.

What Crantz says of the coast of Greenland is not less true of our own rocky sea-margins. “These shores are the best and grandest school for the study of fishes. Here the naturalist may attain a fundamental acquaintance with them, and discover the nature and instincts of each species. It would prove a spacious field of observation for a curious, inquiring mind, which would often fall into a train of profound meditation, as he surveyed the nature and function and relations of the inhabitants of the vast ocean, from the minutest insect, scarce perceptible to the eye, to the monstrous whales, together with the seemingly fabulous great sea-monsters, and the equally inconceivable zoophytes, or” [as then supposed] “half-animal sea productions. Yet, after all, the most speculative and penetrating human mind will never be able to pry so deep into the manifold wisdom of God in his creatures as to search them out to perfection; even the meanest of them, and such as are before every one’s eyes. But, for that very reason, because we are so imperfect, we are never satiated with the study of nature, nor weary of rendering that praise to the Lord of Nature which He expects from His creatures.”

SEPTEMBER.

Good service was done to the cause of science when, some fifteen or twenty years since, Robert Ball of Dublin invented the naturalist’s dredge. A huge unwieldy form of the implement has indeed been long in use among fishermen for the obtaining of oysters and scallops; a clumsy affair, of which the frame, furnished only with a single lip, was four or five feet wide, and the bag was formed of iron rings, two inches in diameter,—a loose and open sort of chain-mail. There was an object in this last arrangement; for while the chain-work retained all oysters of a marketable size, the meshes allowed all to escape which were of less dimensions, and so these remained on the ground to grow bigger for another season.

Naturalists did gladly avail themselves of this uncouth apparatus, and many valuable things were scraped from the sea-bottom thereby; but they never could have used it without regret at the thought of the thousands of unknown and unimagined treasures which must have slipped through those huge meshes. No object of less size than two inches in any diameter had a chance of being brought to the surface; and how many precious specimens range below these dimensions we are now beginning to discover.

Yes; I’m glad I have got a Ball’s dredge; and this fair autumnal morning I mean to use it; to go out with honest Harvey, and scrape the stony sea-bottom in the offing yonder. It is a nice portable affair, that one hand can manage; eighteen inches by four and a half are the dimensions of the frame; the scraping lips are double, one on each edge, so that, however the dredge falls on the bottom, it is sure to scrape; a double bridle from each side meets in a ring to which the rope is made fast; and the bag, some twenty inches deep, is made of stout twine, well netted, with meshes about half an inch in diameter. Owing to the swelling of the twine in the water, there is scarcely anything of value that will escape such a net.

Harvey has carried down everything to Babbicombe Beach, and now all is on board; dredge, sieve, pans, buckets, jars, bottles, ad libitum. And now we run up the mainsail and jib, and with a light westerly breeze and smooth water, lie up for Exmouth, or a little beyond, for about an hour.
