By the poet, young sheep are preferred, the lamb gambolling gaily; unless it be in hymns, where "all we like sheep" are repeatedly described, and much stress is laid upon the straying propensities of the animal. To the scientific mind there is special interest in the sequacity of sheep, their habit of following one another with automatic imitation. This instinct, we are told, has been developed by ages of wild crowded racing on narrow ledges, along precipices, chasms, around sudden spurs and corners, only the leader seeing when, where and how to jump. If those behind jumped exactly as he did, they lived. If they stopped to exercise independent judgment, they were pushed off and perished; they and their judgment with them. All these things, and many that are similar, occur to us when we think of sheep. They are also ewes and rams.
