 race ; a race in which jockeys ride on horseback. 



Ungual Phalanx. The single terminal bone of the 

 horse's foot ; the last joint of his toe ; the hoof. 



Union Course. A famous race course on Long Island, 

 New York, formed in 1821, and discontinued in 1888. Here, 

 in 1823, the celebrated race took place between the great 

 Henry, the "pride of the South," and American Eclipse, in 

 the presence of fifty thousand people. Henry M'on the first, 

 and Eclipse the second and third heats. In 18J:2 the Xew 

 Jersey mare, Fashion, beat the Virginia horse, Boston, on this 

 course. Dexter's first race was over this course. Many of 

 Flora Temple's triumphs were achieved here, and here she 

 twice defeated George M. Patchen. Here Ethan Allen ran for 

 stallion honors ; here George Wilkes' first victory was achieved, 

 and here he defeated Lady Thorne and American Girl. 



Unit. The action of each limb of the horse when in 

 motion or in propulsion, is said to be a " unit." 



Unknown. A term used in a pedigree signifying that 

 the particular sire or dam to which it refers w^as of unknown 

 breeding; an element of uncertain quality in a horse's pedi- 

 gree. Each animal has two parents, four grandparents, and, 

 in theory, at least, eight, sixteen, thirty-two ancestors, each 

 generation of ancestors doubling. Now, in plotting a pedigree, 

 especially of any of the older thoroughbred horses, many of 

 the diverging branches of ancestry will end in " unknown " — 

 oftener in regard to a dam than a sire. As an instance, it 

 may be mentioned that in the pedigree of old Eclipse foaled 

 in 1704, and M^ho lived till near the end of the century, (doubt- 

 less the most celebrated horse of his day), if one traces it back 

 he will soon come upon twelve unknoM^n dams. It is claimed 

 by many expert authorities that these unknown dams are a 

 source of great strength and vitality to a pedigree. 



Unplaced. Having no position; a horse not winning 



any part of a purse is said to be " unplaced."
