He says, "The extreme partiality of the common buzzard to the seasonal task of incubation and rearing young birds has been exemplified in various instances. A few years back, a female buzzard, kept in the garden of the Chequers Inn, at Uxbridge, showed an inclination to sit by collecting and bending all the loose sticks she could gain possession of. Her owner, noticing her actions, supplied her with materials. She completed her nest and sat on two hens' eggs, which she hatched, and afterwards reared the young. Since then she has hatched and brought up a brood of chickens every year.

"She indicates her desire to sit by scratching holes in the ground, and breaking and tearing everything within her reach. One summer, in order to save her the fatigue of sitting, some young chickens just hatched were put down to her, but she destroyed the whole. Her family, in June, 1839, consisted of nine, the original number was ten, but one had been lost. When flesh was given to her, she was very assiduous in tearing and offering it as food to her nurselings, and appeared uneasy if, after taking small portions from her, they turned away to pick up grain."

What is this little mouse-like thing in the grass? how quickly it runs. Now I have got him. No! off again; burrowing under the grass-roots. Now I have him safe enough; he cannot bite me with this glove on. Look at the little rogue, with his soft short silky fur and long nose. See how flexible that pointed nose is; how useful in grubbing amongst the closest herbage, or under the surface of the soil. How sharp are the little creature's teeth. With them he eats worms and the larvæ of various kinds of insects. Well, what is its name? It is the common shrew, and though the form of the body is mouse-shaped, it is, properly speaking, not a mouse at all, being much more nearly related to the mole. It is said that shrews are very fond of fighting, and that if two be confined together in a box, the stronger will conquer the weaker and then eat him. Moles are said to eat their small relatives, but I have never had any evidence of the fact, though it is probable enough. May wanted to know whether cats eat shrews. I have often tried cats with dead shrews, and have always found they will not touch them. I dare say, however, they would kill them. The smell of the shrew is certainly unpleasant, as you may find out from this little fellow I hold in my hand. Mind he does not bite your nose. Now we have examined him I shall let him go. It is no pleasure to take an animal's life, and as this little shrew does no harm but good by destroying insect larvæ, it would be a shame to hurt him. Where injurious creatures must be killed, let us always be careful to take away life so as to cause the least possible pain. Now, would any of you have ever thought that the little shrew I have just released had ever been supposed to be one of the most dangerous enemies to cattle? This was really once believed by our ancestors, who thought that a shrew, by running over the backs of cattle, made them weak in the loins, and that its bite made a beast swell at the heart and die. Absurd as was the belief, the supposed cure for the injury was, if possible, still more ridiculous. It consisted in passing over the cow's back the twigs of a shrew ash. "Now a shrew ash," says Gilbert White, "is an ash whose twigs or branches when applied to the limbs of cattle will immediately relieve the pains which a beast suffers from the running of a shrew-mouse over the part affected, for it is supposed that a shrew-mouse is of so baneful and deleterious a nature, that wherever it creeps over a beast, be it horse, cow, or sheep, the suffering animal is afflicted with cruel anguish and threatened with the loss of the use of the limb. Against this accident, to which they were continually liable, our provident forefathers always kept a shrew ash at hand which, when once medicated, would maintain its virtue for ever. A shrew ash was made thus: into the body of the tree a deep hole was bored with an auger, and a poor devoted shrew-mouse was thrust in alive, and plugged in, no doubt with several quaint incantations long since forgotten." It is marvellous how people could ever have believed such stuff; but equal absurdities are still accepted by many people to this very day; so strong a hold on men's minds have the kindred vices of superstition and ignorance.

Look at these spiders' webs on this hawthorn hedge, they are formed of delicate silken threads, and are of a long funnel shape; the spider occupies the bottom part and soon rushes up should any insect get into the trap, and quickly rushes down and escapes at the back door if your hand enters the front. The top of the funnel is spread out into large broad sheets, and the whole snare is attached by silken cords to the twigs of the bushes. This is the snare and residence of a good-sized species, the Agelena labyrinthica. Such webs are common on hedges, on grass, heath, and gorse. Now you must distinguish between spiders' nests and spiders' snares. The very common wheel-like webs, which you see abundantly on hedges, are snares or traps for insects, and beautiful they look on a dewy morning all strung with liquid pearls. Here under this oak are a number of old acorn-cups of last autumn's produce; the acorns have fallen out and the black cups remain. Do you see a delicate spider's web filling this cup; inside are a quantity of tiny round eggs, and a small spider is keeping guard within; this is a spider's nest. Many spiders spin cocoons for their little round eggs, place them in various situations, and leave them; others show the greatest care for them and carry them about wherever they go. The cocoons of the species whose web or trap we are now looking at are made of strong white silk, each cocoon containing perhaps 100 round eggs, rather yellowish in colour. They are fastened to the inside of a web the spider spins by means of silken pillars formed by a number of threads closely glued together. The sac containing the cocoons is fastened to stems of grass or other objects, and partially hidden by a few withered leaves. "For the purpose of securing their prey," says Mr. Blackwall, the author of a splendid work on 'British Spiders,' "spiders have recourse to divers expedients. Numerous species run rapidly about in quest of those objects which constitute their food; others, approaching their victims with great circumspection, spring upon them from a distance; some lie concealed in flowers or among leaves, seizing such insects as come within their reach; and many species procure a supply of nutriment by means of complicated snares of their own fabrication." Of these snares the most beautiful, as I said, are the "wheel within wheel" nets of the various species of the family Epëiridæ. "What are those spider-like things," asked Willy, "with long thin bodies, you often see skating along the water? they are something like the spiders." They are not spiders at all, but insects called "water-measurers," from their peculiar habit of taking a short skate on the surface of the water and then stopping; having measured that distance, off they go again. However, many spiders do run along on the surface of the water, and you know there is one, the great water-spider, that lives habitually in it. Some years ago I had one of these water-spiders in a glass vessel of water, and saw it spin its curious dome-shaped web which it attached to the sides of the glass and some weeds. These domes are formed of closely woven white silk, in the form of a diving bell or half a pigeon's egg, as De Geer has said, with the opening below. It looks like a half-ball of silver; this appearance is due to a quantity of air. It is, in fact, a huge air-bubble surrounded by a covering of white silk, and, as you may suppose, a very interesting and pretty object. Within this silver dome the spider places her eggs, perhaps a hundred or more in number, which are enveloped in a cocoon, this being attached to the inner side of the dome. "But how," said Jack, "is the bubble formed? Where does the air come from?" You have asked a very interesting question, and one which can be answered; for the question was set at rest by Mr. Bell, an excellent observer and well-known naturalist, about twelve years ago, if I remember rightly. He found that the old spider actually took the air down with her from the surface of the water, and deposited it in her domed house. I shall now quote Mr. Bell's words: "The manner in which the animal possesses itself of the bubble of air is very curious, and, as far as I know, has never been exactly described. It ascends to the surface slowly, assisted by a thread attached to a leaf or other support below and to the surface of the water. As soon as it comes near the surface it turns with the extremity of the abdomen upwards, and exposes a portion of the body to the air for an instant, then with a jerk it snatches, as it were, a bubble of air, which is not only attached to the hairs which cover the abdomen, but is held on by the two hinder legs, which are crossed at an acute angle near their extremity; this crossing of the legs taking place at the instant the bubble is seized. The little creature then descends more rapidly and regains its cell, always by the same route, turns the abdomen within it, and disengages the bubble." Spiders have strong jaws; at the bottom of each hooked jaw there is a small sac which contains a poisonous fluid; this fluid is conveyed by a narrow channel from the sac along the jaw, and is pressed out at an opening or slit at the tip of the fang into the wound inflicted on its victim. The feet of spiders are generally terminated by two or more claws furnished with teeth; by means of these combs the animal is enabled to manage the threads of its web with great dexterity and efficiency.
