Figure 64.—"Female No. 7," when 2 years and 7 months old in October 1956.

Figure 65.—"Female No. 7's" ewe lamb in September 1957 at the age of 17-1/2 months. She has the relatively slender body, low withers, and high horns of her mother. (See fig. 66.)

Figure 66.—"Female No. 7," at 3 years and 7 months in October 1957. Notch at tip of right horn would be another useful characteristic in field identification. Small dark spot on left horn shows here and also in figures 63 and 67, permitting positive location of horn growth stages.

Figure 67.—"Female No. 7," at 3 years and 7 months (right), here 17-1/2-month-old ewe lamb (left), and her 4-month-old ram lamb (center), showing relative sizes and horn development.

Figure 68.—The following pictures show the growth and development of the Old Man, captured as a lamb in the late summer of 1948 and kept in a large fenced inclosure at the Desert Game Range where he was photographed by us annually from 1953 to the date of this writing. March 1953. Age: 5 years.
