The domestic Sow brings forth twice a year, producing from ten to twenty at a litter. She goes four months with young, and brings forth in the fifth. At that time she must be carefully watched, to prevent her from devouring her young. Still greater attention is necessary to keep off the male, as he would destroy the whole litter. Jews and Mahommetans not only abstain from the flesh of swine from a religious principle, but consider themselves defiled by even touching it.
