THE LIGHT-HARNESS BREEDS OF HORSES 81 
of trotting blood emanates, which history pronounces to 
be the most ancient source of two modern breeds, — the 
American Standardbred horse and the Hackney.  Per- 
haps the chief notoriety of Blaze in Thoroughbred circles 
was attained through his being the sire of the dam of 
Herod. He also had two sons of interest in this discus- 
sion, namely, Sampson and Shales. Sampson shows a 
deviation in type from other Thoroughbreds of the time, 
being considered a very large horse, 15.2 hands high, and 
said to be the largest-boned Thoroughbred horse ever bred. 
He was a noted and proved race horse. He sired Engineer, 
sire of Mambrino, sire of Messenger. He was also the 
grandsire of the dam of Useful Cub, that trotted seven- 
teen miles in less than an hour. Shales, the other son of 
Blaze, sired Driver and Scott’s Shales, both of which were 
trotters, and considered by careful investigators to be 
pillars of the Hackney. 
88. Influence of Messenger. — Messenger was im- 
ported in 1788. His line is an unbroken series of trotters. 
He sired Mambrino, which had about a dozen trotting 
sons, in three of which we are chiefly interested: Mam- 
brino, Bishop’s Hambletonian and the mare Silvertail. 
Mambrino sired Mambrino Paymaster, and Abdallah, the 
former the sire of Mambrino Chief, founder of the family 
of that name among Standardbred horses. Abdallah sired 
Hambletonian 10, the founder of the Hambletonian family 
in the Standardbred breed. Silvertail was the dam of 
One Eye, the dam of the Charles Kent mare; and this 
mare was by Imported Bellfounder, which traces back 
through the Fireaways to Driver, the son of Shales, the 
son of Blaze. To get all this clear, the following chart is 
submitted :
