NOTES OF A READER

KNOWLEDGE FOR THE PEOPLE: OR, THE PLAIN WHY AND BECAUSE

Part IV.—Zoology—Birds

This portion illustrates the Economy of Birds, with a few of the most attractive varieties, under European and British, and Foreign Birds. We quote from the "General Economy;" premising that the present Part contains about 250 such illustrations, or Why and Because.

Why are birds usually classed according to the forms of their bills and feet? Because those parts are connected with their mode of life, food, etc., and influence their total habit very materially. Blumenbach.

Why have birds little power of suction?

Because of the narrowness and rigidity of their tongue; as may be seen when they drink, having to hold up their heads, and depend upon the weight of the water for transmitting it into the craw.—Rennie.

Why are birds said to be "poised" in the air?

Because the centre of gravity of their bodies is always below the insertion of their wings, to prevent them falling on their backs, but near that point on which the body is, during flight, as it were, suspended. The positions assumed by the head and feet are frequently calculated to accomplish these ends, and give to the wings every assistance in continuing the progressive motion. The tail also is of great use, in regulating the rise and fall of birds, and even their lateral movements.—Fleming.

Why do birds fly?

Because they have the largest bones of all animals, in proportion to their weight; and their bones are more hollow than those of animals that do not fly. Air-vessels also enable them to blow out the hollow parts of their bodies, when they wish to make their descent slower, rise more swiftly, or float in the air. The muscles that move the wings of birds downwards, in many instances, are a sixth part of the weight of the whole body; whereas, those of a man are not in proportion one-hundredth part so large.

Why are birds covered with feathers?

Because, by this addition to the non-conducting appendices of the skin, birds are enabled to preserve the heat, generated in their bodies, from being readily transmitted to the surrounding air, and carried off by its motions and diminished temperature.—Fleming.

Why are the strongest feathers of birds in the pinions and tail?

Because the pinion-feathers may form, when the wing is expanded, as it were, broad fans, by which the bird is enabled to raise itself in the air and fly; whilst its tail feathers direct its course.—Blumenbach.

Why do birds moult?

Because they may be prepared for winter; this change being analogous to the casting of hair in quadrupeds. During summer, the feathers of birds are exposed to many accidents. Not a few spontaneously fall; some of them are torn off during their amorous quarrels; others are broken or damaged; whilst, in many species, they are pulled from their bodies to line their nests. Hence, their summer dress becomes thin and suitable. Previous to winter, however, and immediately after incubation and rearing of the young is finished, the old feathers are pushed off in succession by the new ones, and thus the greater part of the plumage of the bird is renewed.—Fleming.

Why do birds sing?

Because of the receptacles of air already mentioned but particularly by the disposition of the larynx, which in birds is not, as in mammifera and amphibia, placed wholly at the upper end of the windpipe; but, as it were, separated into two parts, one placed at each extremity. Parrots, ravens, starlings, bullfinches, &c., have been taught to imitate the human voice, and to speak some words: singing birds also, in captivity, readily adopt the song of others, learn tunes, and can even be made to sing in company, so that it has been possible actually to give a little concert by several bullfinches. In general, however, the song of birds in the wild state appears to be formed by practice and imitation.—Blumenbach.

Why do the notes of different species of birds vary?

Because, probably, of the structure of the organs of each species enabling them more easily to produce the notes of their own species, than those of any other, and from the notes of their own species being more agreeable to their ears. These conditions, joined to the facility of hearing the song of their own species, in consequence of frequenting the same places, determine the character of the acquired language of the feathered tribes.—Fleming.

Why are birds equally dispersed in spring over the face of the country?

Because, during that amorous season, such a jealousy prevails between the male birds, that they can hardly bear to be seen together in the same hedge or field. Most of the singing and elation of spirits, of that time, seem to be the effect of rivalry and emulation.—G. White.

Why is August the most mute month, the Spring, Summer, and Autumn through?

Because many birds which become silent about Midsummer, reassume their notes in September; as the thrush, blackbird, woodlark, willow-wren, &c.—G. White.

Why do birds congregate in hard weather?

Because, as some kind of self-interest and self-defence is, no doubt, their motive, may it not arise from the helplessness of their state in such rigorous seasons; as men crowd together, when under great calamities, they know not why? Perhaps approximation may dispel some degree of cold; and a crowd may make each individual appear safer from the ravages of birds of prey and other damages.—G. White.

Why do we so often fail in rearing young birds?

Because of our ignorance of their requisite food. Every one who has made the attempt, well knows the various expedients he has resorted to, of boiled meats, bruised seeds, hard eggs, boiled rice, and twenty other substances that Nature never presents, in order to find a diet that will nourish them; but Mr. Montagu's failure, in being able to raise the young of the curl-bunting, until he discovered that they required grasshoppers, is a sufficient instance of the manifest necessity there is for a peculiar food in one period of the life of birds.—Knapp.

Why have most noctural birds large eyes and ears?

Because large eyes are necessary to collect every ray of light, and large concave ears to command the smallest degree of sound or noise.

Why do stale eggs float upon water?

Because, by keeping, air is substituted for a portion of the water of the egg, which escapes.—Prout.

Why has the breast-bone of all birds which fly, a long ridge or keel?

Because muscles are attached to it, to facilitate their flight.

Why is the plumage of aquatic birds kept dry?

Because the small feathers next the bird fall over each other like the tiles of a roof, and thus throw off the water.

FESTIVALS, GAMES, AND AMUSEMENTS

BY HORATIO SMITH, ESQ.

(National Library—Vol. v.)

The readers of The Mirror will doubtless expect in its pages some notice of the present work; although it belongs to a Series, which as yet possesses but few attractions for our attention. The title of the volume before us, and the name of its author, however, led us to expect better things; and sorry are we to have little but disappointment to report to the reader.

Mr. Smith sets out by telling us, in his Preface, that he has only been able to produce a mediocre book, and at once shows that his task has been by no means a grateful one. He talks of compilation and selection as if they were the very drudgery of literature, although in the present instance he has executed both so indifferently. He speaks of condensing into "one little volume," whereas the plan adopted by him has but little of the labour of condensation, his book being little but slice upon slice, like preserved fruit, instead of being thoroughly mixed and reduced like jelly. With Strutt's Sports and Pastimes, and Ellis's Edition of Brand's Popular Antiquities before him, he might have produced a volume of exhaustless interest and value, set with hundreds of foot-note references, which he has made but few and far between. Nay, with the example of Brand before him (for we see that he is occasionally quoted), it is difficult to conceive how Mr. Smith could overlook so important a point as the distinct acknowledgment of his authorities.

A slight analysis of Mr. Smith's volume will show the reader that our animadversions are not uncalled for.—Thus, upwards of one hundred pages are devoted to the Festival Games and Amusements of the Jews, Greeks, and Romans, meanly as Mr. Smith talks of "learned lore and antiquarian pedantry." Then follow twenty-two pages on, not of, Modern Festivals, &c.: from thence we quote two pages on the amusements of Londoners:—

"In addition to peculiar and extensive privileges of hunting, hawking, and fishing, the Londoners had large portions of ground allotted to them in the vicinity of the city, for such pastimes as were best calculated to render them strong and healthy. The city damsels had also their recreation on the celebration of these festivals, dancing to the accompaniment of music, and continuing their sports by moonlight. Stow tells us that in his time it was customary for the maidens, after evening prayers, to dance and sing in the presence of their masters and mistresses, the best performer being rewarded with a garland. Who can peruse the recapitulation of London sports and amusements, even so late as the beginning of the last century, without being struck by the contrast it presents in its present state, when, as a French traveller observes, it is no longer a city, but a province covered with houses? In the whole world, probably, there is no large town so utterly unprovided with means of healthful recreation for the mass of the citizens. Every vacant and green spot has been converted into a street; field after field has been absorbed by the builder; all the scenes of popular resort have been smothered with piles of brick; football and cricket-grounds, bowling-greens, and the enclosures of open places, set apart for archery and other pastimes, have been successively parcelled out in squares, lanes, or alleys; the increasing value of land, and extent of the city, render it impossible to find substitutes; and the humbler classes who may wish to obtain the sight of a field, or inhale a mouthful of fresh air, can scarcely be gratified, unless, at some expense of time and money, they make a journey for the purpose. Even our parks, not unaptly termed the lungs of the metropolis, have been partially invaded by the omnivorous builder; nor are those portions of them which are still open available to the commonalty for purposes of pastime and sport. Under such circumstances who can wonder that they should lounge away their unemployed time in the skittle-grounds of ale-houses and gin-shops? or that their immorality should have increased with the enlargement of the town, and the compulsory discontinuance of their former healthful and harmless pastimes? It would be wise to revive, rather than seek any further to suppress them: wiser still would it be, with reference both to the bodily and moral health of the people, if, in all new inclosures for building, provision were legally made for the unrestricted enjoyment of their games and diversions, by leaving large open spaces to be appropriated to that purpose.

"Upon a general review of our present prevailing amusements, it will be found, that if many have been dropped, at least in the metropolis, which it might have been desirable to retain, several also have been abandoned, of which we cannot by any means regret the loss; while those that remain to us, participating in the advancement of civilization, have in some instances become much more intellectual in their character, and in others have assumed more elegant, humane, and unobjectionable forms. Bull and bear-baiting, cock-throwing and fighting, and such like barbarous pastimes, have long been on the wane, and will, it is to be hoped, soon become totally extinct. That females of rank and education should now frequent such savage scenes, seems so little within the scope of possibility that we can hardly credit their ever having done so, even in times that were comparatively barbarous."

Truly, as Charles Mathews says, "we are losing all our amusements." Then follow about thirty pages of Holiday Notices; a sort of running commentary on the Calendar. The spaces of the days, however, are sadly disproportioned. Shrove Tuesday occupies upwards of two pages; Good Friday and Easter are pruned into the same space; May Day has upwards of four pages, more than half of which are taken up with the author's own embellishment: still, not a word has he on the poetry of the Day beyond his motto from Herrick. Field Sports, as Hawking and Archery, occupy the next thirty pages; but Mr. Smith is wofully deficient in the latter department: for instance, how is it that he has not even mentioned the archery at Harrow School,⁴ and the existence of archery clubs in the present day.—Bull-fights and Baiting of Animals occupy the next forty pages in two chapters, one of which has been mostly transcribed from the Encyclopaedia Britannica. An original account of a Spanish Bull Fight occupies twenty pages, and is interesting, but rather out of place among English sports. Dancing has thirty pages, for which the Encyclopaedia Britannica has also been very freely taxed. Morris Dancers have ten pages. Jugglers have about the same space, chiefly from Strutt and Brand: Beckmann's chapter might have been added. Music and Minstrels have thirty pages, from Hawkins and Burney. Mr. Singer's curious work has furnished about twenty pages on Playing Cards. Chess is compressed within ten pages! The English Drama, thirty pages, is acknowledged from Hawkins's History of the English Drama, Cibber, and Victor; but "more especially from the Biographia Dramatica," we should say, the weakest source of the four. Malone's Supplement to his Edition of Shakspeare has entirely supplied thirteen pages of Playhouse Notices;—and here the curtain falls—sans Index, or the Author's Farewell.
