62 BULLETIN 1346, U. S. DEPARTMENT OF AGEICULTUEE 
on this continent was recorded in an account of a great hunt organized for 
the viceroy of Mexico in 1540, at a point near the present station of Cazadero 
on the Mexican Central Railroad in extreme southwestern Hidalgo. 
The main herds of antelope in Mexico are undoubtedly located on the 
broad arid plains of Coahuila, Chihuahua, and northeastern Durango. Other 
herds occupy considerable territory in northwestern Sonora, some occasion- 
ally ranging back and forth across the border between Sonora and Arizona, 
and others are located in Lower California. From information received it 
appears possible at this time that, in general, antelope may be holding their 
own in Mexico. 
On October 1, 1922, a close season of 10 years on antelope, which had been 
established by President Obregon, became effective. This should serve to 
lessen the number of these animals killed and so favor their increase. There 
are great areas of sparsely 
occupied plains on the 
northern Mexican table- 
lands where they might 
find a home far into the 
distant future. 
To assist in safeguard- 
ing the antelope and other 
game animals of northern 
Sonora the Permanent 
Wild Life Protection Fund, 
through Doctor Horna- 
day, has entered into an 
agreement with the Mexi- 
can Government whereby 
it employs Ben Tinker as 
game warden, with head- 
quarters at Tucson, Ariz., 
to work along both sides 
of the Arizona-Sonora bor- 
der to prevent poaching. 
It is conservatively esti- 
mated that there are 2,395 
antelope in Mexico, of 
which 1,300 are estimated to be in Chihuahua, Durango, and Coahuila, and 
500 in Lower California. The remainder are more definitely known in Sonora. 
These numbers will serve as a working basis until there is opportunity to get 
more complete information. It is probable that there may be many more on 
the plains of Chihuahua and Coahuila than here estimated. Tlie following 
details of distribution are based on a letter received from Professor Lopez in 
January, 1924, and from other information available on the subject. It is 
grouped under States and the Territory of Lower California, as follows 
(figs. 20 and 21) : 
COAHUILA 
In the great Valley of La Encantada, to the west of Muzquiz, bands of 
50 to 100 antelope occur. They are also about the Hacienda de San Antonio, 
and are more abundant about the Hacienda de Paila and on the plains about 
the neighboring mountain range of Espianzo. Most of the antelope in Coa- 
huila are located west of the railroad which runs south from Eagle Pass, 
Tex., to Saltillo, and north of the railroad extending from the last-named 
place westward to Torreon.
