The New International Encyclopædia…
“ A lean head and neck, firmly set on good oblique shoulders; a strong back and loin, deep body, wide hips, good quarters, and firm legs and feet. Among horsemen the following terms are in use: A stallion is a male horse, and when gelded is termed a gelding. A mare is the female. Animals of both sexes when young are termed foals; the male foal is a colt, and the female a filly. Young animals become ‘of age’ when the outer incisors (corner nippers) are developed. A horse is ‘aged’ when in its eighth or ninth year, a fact determined by the front teeth. ”
