46 THE BREEDS OF LIVE-STOCK 
and Norfolk were the original home of the Hackney, at 
an early time known also as the Norfolk trotter; and 
Yorkshire became prominent in the development of this 
breed, through its adaptability to light horses and supe- 
riority over the counties of Shropshire and Lincoln- 
shire in that the Yorkshireman was an enthusiastic horse- 
man. To carry the postulate to its full and more 
recent application, it is necessary only to direct attention 
to what Kentucky, Vermont, Virginia, Tennessee and 
other states possessing the character of soil and people 
referred to, have accomplished. Conversely, apply what 
has been stated to be the evolution of draft breeds, and 
it will be apparent that the heaviest breeds of draft 
horses come from the lower and more level lands, with 
their more lush vegetation. 
45. Breeding saddle horses. — Continuing our refer- 
ence to Yorkshire and Norfolk, it should be said that the 
demand during the earliest time was for a horse that could 
trot fast under saddle, and the horsemen of these two 
counties vigorously took up the work of breeding a stoutly 
built fast trotting horse of as much endurance as possible. 
It is said (Wallace, Live-Stock) that the Norwegian horse 
was used at a very early day on the common mares of 
these counties, as it was in Norfolk and Yorkshire where 
the Norse invaders had their principal strongholds in Eng- 
land. The influence of this on the breed may be slighted 
when the more potent influence of the Thoroughbred is 
considered. It is also of interest to mention that even 
the blood of the Standardbred trotter found its way into 
some of the Hackney pedigrees through Shepherd F. 
Knapp, No. 282 in the register of Standardbred horses. 
The main source of the Hackney blood lines runs back to 
Arabian origin through the Thoroughbred, being similar
