In rooms, it is common to let it hop about, giving it a retired corner to sleep; it is, however, also kept in cages, where it sings best. Whatever form may be given to these cages, they must be at least eighteen inches long, nine wide, and fifteen high; the bottom should have a drawer in which enough of river sand should be kept for this scratching bird to be able to roll and dust itself conveniently. It is also a good plan to have in a corner a little square of fresh turf, which is as beneficial as it is agreeable. The top of the cage must be of linen, since, from its tendency to rise for flight, it would run the risk of wounding its head against a covering of wood or iron wire, especially before it is well tamed. The vessels for food and drink must be outside, or, which I prefer, a drawer for the food may be introduced in the side of the cage: sticks are not necessary, as the lark does not perch. When it is allowed to hop free in a room, the latter must be very clean and neat, otherwise a thread or hair may entangle the feet, and if not removed it easily cuts the skin, maims the bird, and the entangled toes shrink and fall off. FOOD.--When wild, the food consists of insects, especially ants' eggs; also of all kinds of seeds, and in autumn of oats, which these birds skin by striking them against the ground, their beak being too weak to shell them alone. In the spring the sprouting seeds and young buds, also the blades of young grass, are eaten, and grains of sand help their digestion. In the house, if the lark is hopping about, nothing is better than the first universal paste described in the Introduction; but if caged the second will suit it better. Poppy-seed, bruised hemp, crumb of bread, and plenty of greens, as lettuce, endive, cabbage, or water-cress, according to the season, must be added. A little lean meat and ants' eggs are favourite delicacies, which make it gay and more inclined to sing. When old larks are first made prisoners, they must be fed only with oats and poppy-seed to reconcile them to captivity.
