“Natural instincts are lost under domestication: a remarkable instance of this is seen in those breeds of fowls which very rarely or never become “broody,” that is, never wish to sit on their eggs. Familiarity alone prevents our seeing how universally and largely the minds of our domestic animals have been modified by domestication. It is scarcely possible to doubt that the love of man has become instinctive in the dog. All wolves, foxes, jackals, and species of the cat genus, when kept tame, are most eager to attack poultry, sheep, and pigs; and this tendency has been found incurable in dogs which have been brought home as puppies from countries, such as Tierra del Fuego and Australia, where the savages do not keep these domestic animals. How rarely, on the other hand, do our civilised dogs, even when quite young, require to be taught not to attack poultry, sheep, and pigs! No doubt they occasionally do make an attack, and are then beaten; and if not cured, they are destroyed; so that habit, with some degree of selection, has probably concurred in civilising by inheritance our dogs. On the other hand, young chickens have lost, wholly by habit, that fear of the dog and cat which no doubt was originally instinctive in them, in the same way as it is so plainly instinctive in young pheasants, though reared under a hen. It is not that chickens have lost all fear, but fear only of dogs and cats, for if the hen gives the danger-chuckle, they will run (more especially young turkeys) from under her, and conceal themselves in the surrounding grass or thickets; and this is evidently done for the instinctive purpose of allowing, as we see in wild ground-birds, their mother to fly away. But this instinct retained by our chickens has become useless under domestication, for the mother-hen has almost lost by disuse the power of flight.”
A cook of roughly the same moment, setting down the same dish.
390. INGREDIENTS.--1/2 lb. of chestnuts, 1/2 pint of white stock, 2 strips of lemon-peel, cayenne to taste, 1/4 pint of cream or milk. _Mode_.--Peel off the outside skin of the chestnuts, and put them into boiling water for a few minutes; take off the thin inside peel, and put them into a saucepan, with the white stock and lemon-peel, and let them simmer for 1-1/2 hour, or until the chestnuts are quite tender. Rub the whole through a hair-sieve with a wooden spoon; add seasoning and the cream; let it just simmer, but not boil, and keep stirring all the time. Serve very hot; and quickly. If milk is used instead of cream, a very small quantity of thickening may be required: that, of course, the cook will determine. _Time_.--Altogether nearly two hours. _Average cost_, 8d. _Sufficient_, this quantity, for a turkey.
