Hedgehogs feed on insects, slugs, frogs, eggs, young birds in the nest, mice, fallen fruits, and the roots of vegetables, especially the plantain, boring into the ground to get at these substances. They will clear a house of black beetles in a few weeks, as I can attest from my own experience. My kitchen was much infested, not only by them, but by a sort of degenerated cockroach, descended from the better conditioned Blattæ, brought in my packages from a tropical country, and which had resisted all efforts for their extermination, such as boiling water, pepper, arsenic-wafers, mortar, etc. At last, a friend, whose house had been cleared of beetles by a hedgehog, made the animal over to me, very much to the discomfort of my cook, to whom it was an object of terror. The first night of its arrival a bed was made for it in a hamper, half full of hay, and a saucer of milk was set within. The next morning the hedgehog had disappeared, and for several days the search made for it was fruitless. That it was alive was proved by the milk being drunk out of the saucer in which it was placed. One night I purposely went into the kitchen after the family had been for some time in bed, and, as I opened the door, I saw the little creature slink into a hole under the oven attached to the grate. Fearing this would sometimes prove too hot for it, I had some bricks put in to fill up the aperture. The next night the bricks were pulled away, and overturned, evincing a degree of strength which astonished us; but, after that, we left the animal to its own care. The beetles and cockroaches visibly disappeared, but as they disappeared other things also vanished; kitchen cloths left to dry at night were missing; then, a silk handkerchief. At last a night-cap left on the dresser was gone; and these abstractions were most mysterious. The next day there was a general search in possible and impossible places, and the end of a muslin string was seen in the oven-hole; it was seized on, and not only was the night-cap dragged out, but all the missing and not missing articles which the hedgehog had purloined; most of them were much torn, and it was supposed that the poor beast had taken possession of them to make a soft bed. I have not seen such a propensity noticed elsewhere, and it may be a useful hint to those who keep hedgehogs. All endeavours to make this animal friendly were unavailing; but I am told, that hedgehogs are frequently quite domesticated; and even shew a degree of affection.
