enough to draw attention as the bird flies through the underwood; but at all events it is only a short cry, and the bird is soon out of sight; but the Shrike remains on or near the nest while it continues to utter its harsh screams, and flies away noisily when the intruder is close at hand.

The nest itself is large, and not concealed with any care, while around it are stuck humble bees, cocktail beetles, ground beetles, and a variety of other insects, each impaled upon a thorn, and forming admirable indications to the nest-hunter. Sometimes, but seldom, young birds are impaled instead of insects, and in such cases they are always callow nestlings, and are fixed by a thorn run between the skin and the flesh, instead of being pierced through the body, as is the method employed with insects.

There is a popular idea that the bird always has nine impaled creatures at hand, and that when it eats one it catches another, and with it replaces the one which has been eaten. In consequence of this notion, which prevails through several counties, the bird is called Nine-killer. The generic name, Enneoctonus, is composed of two Greek words which have a similar signification. So strongly is this idea held by some persons, that I have seen a treatise upon instinct, where the Shrike was gravely produced as an example of arithmetical powers possessed by birds. These theories generally fail when confronted by facts. I have seen numberless Shrikes' nests; and, though in some cases there may been nine impaled animals, in some there were more and in others less.

The nest itself is neatly, though loosely, built of roots, moss, wool, and vegetable fibres, and is lined with hair. I have mostly noticed it about five feet from the ground; and, although it is said to be closely hidden, have always found it a peculiarly conspicuous nest.

THE last branch-building bird which will be mentioned in these pages is the well-known HEDGE SPARROW, or HEDGE ACCENTOR, as it ought rightly to be called (Accentor modularius). The bird derives its popular name from two peculiarities, one of person and the other of habits. As its general tints are brown and black, the name of Sparrow has been given to it, although it rightly belongs to the warblers. It may easily be distin

guished from the sparrow by its slender form, its blue-grey colour, and the absence of the black patches that mark the head and throat of the true sparrow.

It is very plentiful in England, and that it should be so is rather remarkable on account of the exposed situation and conspicuous form of its nest. The red-backed shrike is remiss enough in placing its nest; but the Hedge Sparrow seems to be utterly heedless on the subject, and appears absolutely to invite the attention of its foes, which are many.

First and foremost comes the bird-nesting boy, whose eyes are generally so sharp that to conceal a nest from him is no easy matter. Then the Hedge Sparrow is one of the earliest builders, and so hasty is it in its proceedings that I have seen the halffinished nest filled with the snows of early spring. The bird had been in such a hurry to set up housekeeping that she would not even wait until the leaves were sufficiently large to shelter the nest; and, as might be expected, the snow found an easy entrance into the unprotected edifice. In consequence, moreover, of this passion for early building, the nest is so conspicuous an object in the leafless hedge, that the most casual glance cannot fail to detect it, while the natural foes of the bird, namely, the boy, the stoat, the cat, cuckoo, and others, find it the easiest of their prey.

The boy, for example, who might not be able to reach the nest of the shrike, which is placed some five or six feet from the ground, has no difficulty whatever in harrying that of the Hedge Sparrow, which is seldom more than two feet from the ground. Moreover, although the older nest-hunters will not trouble. themselves about eggs so common as those of the Hedge Sparrow, the novices, and even many who ought to know better, can never resist the round, shining blue shells, as they lie snugly packed away in their basket-like receptacle.

Then there is the cuckoo, that flies about the hedgerows, peering into every nest and looking out for a foster home for her eggs, which she cannot hatch, and for the young which she cannot cherish. There is, perhaps, no nest which is easier to be seen or more accessible when discovered than that of the Hedge Sparrow, and the consequence is, that the cuckoo's egg is oftener to be found in the nest of the Hedge Sparrow than in that of any other bird. This circumstance is certainly unfortunate to

the Hedge Sparrow, who is obliged to give up the whole of her nest to a supposititious offspring, and to bestow upon a single intruder all the care and attention which would otherwise have been lavished upon the five rightful occupants.

Besides the cats, rats, and weasels, there are direful feathered foes, such as the shrike, which steals away the young and carries them to its home, where it hangs them up in its natural larder, and the magpie, which will sometimes work great havoc among the young or eggs. Now and then the owl makes a meal of a young bird, as I can testify from personal experience, and the viper is always ready to glide up the stems of the shrubs amid which the bird has built, to insert its baleful head into the nest, and to swallow the callow young.

Still, as the Hedge Sparrow generally produces two broods of young in a year, and sometimes three, all her offspring are not destroyed by these foes, and she may have the satisfaction of rearing some of her own. The nest is nicely, substantially, but not elegantly made, as, indeed, might be inferred from its lowly position. Nests upon or near the ground are very seldom made with much attention to elegance of architecture, the greatest trimness of nest-building skill being displayed in those homes which are placed upon lofty branches or suspended from slender twigs. It is a rather large nest, and is made of moss, wool, hair, and similar materials. As is generally the case with the group of birds to which the Hedge Sparrow belongs, the eggs are five in number, and on an average, three young in cach brood attain maturity.

WE have already seen several nests built by SPIDERS, some of which are made in the earth, others are strictly pensile, and others may fairly come into the present group. The specimens

from which the drawings were made are in the collection of the British Museum, some in the upper and others in the lower rooms. Of the architects, the manner in which the nests were made, and the reasons why they were so singularly constructed, I can say nothing, because no record is attached to the specimens. Still, they are so curious that they have found a place in this work, and it is to be hoped that the very fact of their publicity will induce travellers to search for more specimens and to describe their history.

Differing as they do in shape, colour, and material, they have one object in common, namely, the rearing of the young. They are clearly nests in the true sense of the word, being devoted not to the parents, but to the offspring. At the upper part of the illustration may be seen a number of long, spindle-shaped bodies, suspended from a branch. These are drawn about half the full size, in order to allow other specimens to be introduced into the same illustration for the purpose of comparison. In colour they are nearly white, with a slight yellowish tinge, and are very soft and delicate of texture, so that when viewed in a good light they form a very striking group of objects.

In the opposite upper corner of the illustration may be seen a remarkable nest, which few would recognise as the work of a spider. Such, however, is the case, the creature being urged by instinct to take several concave seed-pods, and to fix them together as seen in the drawing. The seed-pods are fastened firmly together with the silken thread of which webs are made, and in the interior the eggs are placed. The drawing is reduced about one-third in proportion to the actual object. Several of these singular nests are in the collection at the British Museum.

Occupying the lower part of the illustration is seen a leaf upon which are piled a number of fragments of leaves, so as to form a rudely conical heap. This is also the work of a spider, and is made with even more ingenuity than the two preceding specimens. In the first instance, the spider has spun a hollow case of silk, similar in principle of construction, though not in form, to the spherical egg cases made by several British spiders. In the second instance, the creature has chosen a number of concave seed-pods, and, by adjusting their edges together and fastening them with silk, made a hollow nest, which only requires to be lined in order to make it a fit nursery for the young. But, in
