Part 8 (2/2)
Upon looking through the instrument, we find the fluid swarming with animals of various shapes and magnitudes. Some are darting through the water with great rapidity, while others are pursuing and devouring creatures more infinitesimal than themselves. Many are attached to the twig by long delicate threads, several have their bodies inclosed in a transparent tube, from one end of which the animal partly protrudes and then recedes, while others are covered by an elegant sh.e.l.l or case. The minutest kinds, many of which are so small that millions might be contained in a single drop of water, appear like mere animated globules, free, single, and of various colours, sporting about in every direction.
Numerous species resemble pearly or opaline cups or vases, fringed round the margin with delicate fibres, that are in constant oscillation. Some of these are attached by spiral tendrils; others are united by a slender stem to one common trunk, appearing like a bunch of hare-bells; others are of a globular form, and grouped together in a definite pattern, on a tabular or spherical membranous case, for a certain period of their existence, and ultimately become detached and locomotive, while many are permanently cl.u.s.tered together, and die if separated from the parent ma.s.s. They have no organs of progressive motion, similar to those of beasts, birds, or fishes; and though many species are dest.i.tute of eyes, yet possess an accurate perception of the presence of other bodies, and pursue and capture their prey with unerring purpose.

THE CANARY.
This bird, which is now kept and reared throughout the whole of Europe, and even in Russia and Siberia, on account of its pretty form, docility, and sweet song, is a native of the Canary Isles. On the banks of small streams, in the pleasant valleys of those lovely islands, it builds its nest in the branches of the orange-trees, of which it is so fond, that even in this country the bird has been known to find its way into the greenhouse, and select the fork of one of the branches of an orange-tree on which to build its nest, seeming to be pleased with the sweet perfume of the blossoms.
[Ill.u.s.tration: CANARY.]
The bird has been known in Europe since the beginning of the sixteenth century, when a s.h.i.+p, having a large number of canaries on board destined for Leghorn, was wrecked on the coast of Italy. The birds having regained their liberty, flew to the nearest land, which happened to be the island of Elba, where they found so mild a climate that they built their nests there and became very numerous. But the desire to possess such beautiful songsters led to their being hunted after, until the whole wild race was quite destroyed. In Italy, therefore, we find the first tame canaries, and here they are still reared in great numbers. Their natural colour is grey, which merges into green beneath, almost resembling the colours of the linnet; but by means of domestication, climate, and being bred with other birds, canaries may now be met with of a great variety of colours. But perhaps there is none more beautiful than the golden-yellow, with blackish-grey head and tail.
The hen canary lays her eggs four or five times a year, and thus a great number of young are produced.
As they are naturally inhabitants of warm climates, and made still more delicate by constant residence in rooms, great care should be taken in winter that this favourite bird be not exposed to cold air, which, however refres.h.i.+ng to it in the heat of summer, is so injurious in this season that it causes sickness and even death. To keep canaries in a healthy and happy state, it is desirable that the cage should be frequently hung in brilliant daylight, and, if possible, placed in the warm suns.h.i.+ne, which, especially when bathing, is very agreeable to them. The more simple and true to-nature the food is, the better does it agree with them; and a little summer rapeseed mixed with their usual allowance of the seed to which they have given their name, will be found to be the best kind of diet. As a treat, a little crushed hempseed or summer cabbage-seed may be mixed with the canary-seed. The beautiful gra.s.s from which the latter is obtained is a pretty ornament for the garden; it now grows very abundantly in Kent.
The song of the canary is not in this country at all like that of the bird in a state of nature, for it is a kind of compound of notes learned from other birds. It may be taught to imitate the notes of the nightingale, by being placed while young with that bird. Care must be taken that the male parent of the young canary be removed from the nest before the young ones are hatched, or it will be sure to acquire the note of its parent. The male birds of all the feathered creation are the only ones who sing; the females merely utter a sweet chirrup or chirp, so that from the hen canary the bird will run no risk of learning its natural note.
INDUSTRY AND APPLICATION.
Diligence, industry, and proper improvement of time are material duties of the young. To no purpose are they endowed with the best abilities, if they want activity for exerting them. Unavailing, in this case, will be every direction that can be given them, either for their temporal or spiritual welfare. In youth the habits of industry are most easily acquired; in youth the incentives to it are strong, from ambition and from duty, from emulation and hope, from all the prospects which the beginning of life affords. If, dead to these calls, you already languish in slothful inaction, what will be able to quicken the more sluggish current of advancing years? Industry is not only the instrument of improvement, but the foundation of pleasure. Nothing is so opposite to the true enjoyment of life as the relaxed and feeble state of an indolent mind. He who is a stranger to industry, may possess, but he cannot enjoy. For it is labour only which gives the relish to pleasure.
It is the appointed vehicle of every good man. It is the indispensable condition of our possessing a sound mind in a sound body. Sloth is so inconsistent with both, that it is hard to determine whether it be a greater foe to virtue or to health and happiness. Inactive as it is in itself, its effects are fatally powerful. Though it appear a slowly-flowing stream, yet it undermines all that is stable and flouris.h.i.+ng. It not only saps the foundation of every virtue, but pours upon you a deluge of crimes and evils.
It is like water which first putrefies by stagnation, and then sends up noxious vapours and fills the atmosphere with death. Fly, therefore, from idleness, as the certain parent both of guilt and of ruin. And under idleness I include, not mere inaction only, but all that circle of trifling occupations in which too many saunter away their youth; perpetually engaged in frivolous society or public amus.e.m.e.nts, in the labours of dress or the ostentation of their persons. Is this the foundation which you lay for future usefulness and esteem? By such accomplishments do you hope to recommend yourselves to the thinking part of the world, and to answer the expectations of your friends and your country? Amus.e.m.e.nts youth requires: it were vain, it were cruel, to prohibit them. But, though allowable as the relaxation, they are most culpable as the business, of the young, for they then become the gulf of time and the poison of the mind; they weaken the manly powers; they sink the native vigour of youth into contemptible effeminacy.
