RACING CONSIDERED AS A MEANS OF IMPROVING 
BREEDS OF HORSES FOR GENERAL USE, 
AND FOR MILITARY SERVICE. 
[Concluded from page 100.] 
By well-directed procedures such as these, always selecting 
the breed uniting in their conformation and temperament the 
best qualities of speed, and coupling them together without 
mixture, have the English succeeded in framing their race-horse. 
Whenever any end was to be achieved, they have never failed 
to accomplish it, regardless of the time, the expense, natural or 
incidental obstacles, and any struggles they might have to make 
against circumstances often directly opposed to their work of 
animal improvement. We have no such perseverance as this 
in Fiance. We lack the pertinacity indispensable to the per- 
fection of breed in the manner in which it has been brought 
about in England. With the exception of Merinos, we possess 
no kinds of animals other than are indigenous to our soil. 
Nevertheless, we have made attempts to follow the example of the 
English, not to produce a race-horse like theirs, but to preserve 
such as we have bought lrom them. But the race-horse has 
proved to be an ar; ificial genus, perfectly distinct from every 
other, and one w hich in France w'e have not been able either to 
produce or maintain, save in the hands of a very limited num- 
ber of proprietors equal to the task in point of fortune and skill 
in management. 
The production of the cavalry horse must differ considerably 
from that of the race-horse, in being more easy, more simple, 
and especially more economical. A racer must be of a nervous 
temperament, highly irritable and vigorous, and should be able 
to call forth all his power and impetuosity in the short space of 
time in which he is engaged in the race, supposing even that he
