Love, which in all animals is the most general and lively sensation, seems to be the only one which gives any vivacity to the ram. When he feels any such emotions, he becomes petulant, fights, and will sometimes attack even his own shepherd. The ewe, however, even at those times, does not appear more animated; and has only instinct sufficient not to refuse the approaches of the male, to chuse her food and to know her own lamb. Instinct is more certain as it is more mechanical. The young lamb, among a numerous flock, will search and find out its mother, and will seize its teat, without ever being mistaken. It is also said, that sheep are sensible to the pleasures of musick; that they brouze with more assiduity, are better in health, and fatten sooner when they hear the shepherd's pipe; but it appears more probable that music serves to amuse the shepherd, and that it is to this solitary, idle life, that we owe the origin of the art. These animals, whose understandings are so simple, are also of a very weak constitution. They cannot walk long; travelling weakens and exhausts them; and when they run, they pant and are soon out of breath. The great heat of the sun, is as disagreeable to them, as too much moisture, cold, or snow. They are subject to many disorders, the greatest part of which are contagious. Superabundance of fat sometimes kills them, and always prevents the ewes from having young. They suffer a great deal in breeding, have frequent abortions and require more care than any other domestic animal.[H] [H] There appears in the text a degree of unusual asperity against this harmless animal, and all its imperfections seem pictured in glaring colours, but in this, as well as in several other particulars, some exaggeration is adopted, since scarce any domestic animal, at the time of bringing forth, requires less assistance than the ewe does in general.
