In the house, as this species is more delicate than the preceding, it is well to vary the food, and to give it occasionally, independent of the universal paste, poppy-seed, oats, hemp, sprouting wheat, fresh curds, fresh and dried ants' eggs, minced ox heart, meal worms, and the like. When one of these birds is caught by the net or otherwise, the best things to induce it to eat when it reaches the bird-room are poppy-seeds and ants' eggs. I have seen two wood-larks which had been kept in a cage for eight years, very healthy and gay, with their feet quite free from disease, and singing perfectly. Their food consisted of crumbs of white bread and pounded hemp-seed mixed together; a piece of white bread, enough for the day, soaked in milk, which was poured boiling over it every morning, was also furnished; and finally, some ants' eggs, given two or three times a day as a treat. The bottom of the cage was also covered with sand, which was changed regularly every day, as well as the water. They were always kept in summer outside the window, exposed to the free air, screening them from the sun by covering the top of the cage with a sheet of paper or piece of linen by way of parasol. The success of this mode of treatment sufficiently proves its advantage. The cage was furnished with two bars, because the wood-lark perches. BREEDING.--The wood-lark builds among the heath, under juniper bushes, in hedges, high grass, or under a green hillock in fields near the woods, or in copse wood. The nest is made of dry blades of grass, mixed with moss, wool, and hair. The eggs are variegated with light gray and brownish violet. The young may be bred up with bread soaked in milk, and ants' eggs. They readily learn the different songs of the birds with which they are imprisoned; but this medley is less agreeable to me than their natural song. DISEASES.--To the list of diseases already given, to which the wood-lark may be subject, I must add one which is peculiar to it. This attacks the feet and renders them extremely brittle. I cannot too strongly recommend to clean them carefully from everything which might entangle them; a single hair may cut them, so that the toes shrivel, or ulcerate and fall off. They become so brittle with age, that with all my cares I could never keep any beyond four years; the least thing breaks them. Most of the wood-larks which I have had perished from broken legs; and this peculiarity I have remarked in no other species of bird. We see from these instances, that if birds allowed to hop about a room enjoy more space and free exercise, they are also subject to more inconveniences and disadvantages than caged birds. Their food is neither so appropriate or regular; they cannot be kept so clean; their feet are almost inevitably injured; and lice devour them, without the power of prevention.
