Battleship, and War Admiral are some of his famous 
sons, while Seabiscuit, the 1937 handicap champion,

Impatient of common work, and apt to be nervous 
and excitable, due in part to his strenuous training, 
the Thoroughbred has unusual speed, endurance, and 
courage of a high degree. 
He is extremely refined in appearance. He has a 
slender, graceful body built for speed. His head and 
ears are small and well formed, his neck is long, slen¬ 
der, and muscular, and his legs are strong and clean- 
cut. He has a well developed chest and shoulders, and 
his quarters are strongly muscled and full of driving 
power. The Thoroughbred weighs about 1100 pounds, 
and averages between 15.2 and 16 hands in height. 
The hand used in measuring horses equals four 
inches. 
The race horse is black, brown, bay, chestnut, or 
grey. He has no lines, stripes, or large spots. The 
markings, if any, usually are white stockings and a 
blaze or star of white on the face. 
The men and boys who ride these Thoroughbred 
race horses are called jockeys. Theirs is a task that 
calls for the utmost in daring, courage, and fine horse-
