Chapter XXVII.

1. Bears perform the act of sexual intercourse in the manner already described, not mounting upon each other, but lying down upon the ground. The female is pregnant thirty days, when she produces one or two, or at the outside five cubs. The fœtus is smaller, in proportion to the size of the parent, than that of any other animal; for it is less than a weasel, and greater than a mouse. It is without hair and blind, and its legs and almost all its parts are without joints. Its season of sexual intercourse is in March. The cubs are born at the time of concealment. At this season both the female and the male are very fat. When they have brought up their young, they show themselves in the third month of the spring. The porcupine also conceals itself, and is pregnant for the same number of days, and in other respects resembles the bear. It is very difficult to capture the she bear when pregnant.
