These troublesome little insects first infest the cages, and then prey upon the poor birds. Under the ornaments on the heads of the posts, and under the perches, and about the head of the cage, are the places they are generally found. They are not so fond of the lower parts of the cage. I am happy to make public a destroyer of those tormentors of my feathered favorites, which I have used with complete success, and without the least injury to the birds. Take about half an ounce of corrosive sublimate, and dissolve it in a pint of spirits of wine, or high proof alcohol, and apply it with a hair-pencil; it kills the insects immediately, and then penetrates into the wood, leaving nothing that the bird can pick; and wherever you touch with it there will be no insect, at least that season. This solution should be marked and carefully put away, as it is rank poison.
