Information Concerning the Colorado Carriage Horse 
Breeding Station 
By JOHN O. WILLIAMS 
This circular is not intended as a publication of any results 
attained in the carriage horse breeding experiment, but is intended 
as a circular of information so that interested persons may acquaint 
themselves with the object of the experiment conducted at the Colo¬ 
rado Breeding Station and the conditions by which they may avail 
themselves of the services of the various stallions in use at the 
station. 
HISTORY AND OBJECT OE EXPERIMENT. 
On July i. 1904 an appropriation of $25,000 by Congress be¬ 
came available to the U. S. Bureau of Animal Industry for ex¬ 
periments in animal breeding and feeding in cooperation with the 
State Experiment Stations. Under this Act, carriage horse breed¬ 
ing was inaugurated in cooperation with the Colorado Experiment 
Station. 
The first purchase of foundation stock was made in December, 
1904 from George D. Rainsford, Diamond, Wyoming, and com¬ 
prised six mares of excellent breeding and good carriage conforma¬ 
tion. The next purchase was made in February, 1905 and included 
the standard-bred stallion “Cannon” 32917 (formerly shown as 
Glorious Thundercloud) and twelve trotting-bred mares of superior 
merit as show animals. These mares were bred in the various 
middle-western states and in Kentucky. The next purchase was 
made in June, 1906 and included the two saddle-bred mares Beat¬ 
rice 2079 (S) and Mambrina 2400 (S). The last purchase was 
made in March, 1908 and comprised four mares from various 
breeders in Kentucky. These mares were Golden Picture 2788 
(S) ; Bethel Princess 4796 (S) ; Barthenia McCord 4223 (S), 
and Elvira Lindsey 3083 (S). 
The above named animals constitute the foundation animals 
of the experiment. The progeny of the foundation mares are care¬ 
fully selected, and those adhering closely to the desired type are 
retained for breeding purposes. New blood will also be introduced 
from time to time through mating the offspring of the foundation 
mares to stallions other than those in use at the station, as well as 
through the purchase of additional animals. 
The object of the work is to study the possibilities of evolving 
an American carriage horse from the American trotter, Morgan, 
and American saddle horse. The trotter is being used as the basis 
of the work and the two other native-blood lines are being used 
to supply the desired qualities they are known to possess. Through 
judicious blending of these blood lines, the ultimate American
