animals in parks and on low pasture lands 
where the grass is rich have neither the 
same speed nor equal endurance 
The number of animals should be strictly 
limited in accord with the area of the stud 
farm, which should be sufficiently extensive 
to allow periodical changes to fresh land ; 
one yearling to every four or five acres is 
plenty. On this point my experience in 
breeding stock, especially horses, has led me 
to form a very strong opinion 
EXPERIENCE GAINED WITIL ITEAVY ILORSES 
AND HACKNEYS 
An instance of the benefit derived from 
the treatment advocated may be mentioned 
here, though it is an experience gained in 
breeding heavy horses 
The theory of fresh grazing has been 
tested by placing a certain number of mares, 
on their return from service by the best sire 
money could procure, upon land where the 
pasture was not fresh; in the same year an 
equal number of mares, served by the same 
sire under identically similar circumstances, 
have been placed on pastures which had 
been freshly laid down, or upon old grass 
land on which horses had not been grazed 
for several years
