at the bottom and then can be tied at the top with stout cord. Room for a 
water can and space for grain should be allowed in the front. Coarse straw 
at least 3 inches deep should be placed inside for a bed while in transit. 
The express company charges one and one-half times the first-class rate on 
live animals, but does not include in the weight the feed necessary while en 
route. Water and feed should not be placed in the crates, therefore, until after 
they are weighed and billed out. 
TRANSPORTING ANTELOPE IN CRATES 
Animals should be crated singly, for where two or more are together they 
will cut each other with their sharp hoofs. When one lies down the other will 
invariably step on it. In the 240 miles that we transported the fawns from 
Diessner to Reno by automobile truck they were crated singly and endured the 
trip in fine shapa We left Diessner at 2 o'clock in the afternoon and, driving 
all night, arrived in Reno at 8.15 in the morning, thus making the trip during 
the coolest period of the day. 
We have demonstrated beyond a doubt that young antelope can be success- 
fully taken from their natural range and raised if care is exercised in handling 
them. 
Great care must be taken to keep all milk containers, bottles, and nipples 
perfectly clean, and I would suggest that if any more antelope are taken in 
this district they be transferred direct to Reno as soon as the required number 
is captured, where unlimited supplies of milk can be obtained and also all other 
necessary food. It is not necessary to have such a large inclosure as we made 
at the Wood ranch, and I believe the antelope become gentle more readily 
where they see ipeople constantly passing. 
RESULTS OF A CENSUS OF EXISTING ANTELOPE 
For many years the Biological Survey has been engaged in deter- 
mining the former and present range of the pronghorn. In 1922 it 
became evident that the time had arrived for active measures leading 
to their conservation if their extermination was to be avoided. In 
order to form a basis on which intelligent conservation measures 
might be built a definite census of the surviving pronghorns vras 
undertaken. This was continued from 1922 well into 1924 through 
field men of the Biological Survey, with the active and friendly co- 
operation of State game officials, State game protective associations, 
and individuals, not only in the United States but in Canada and 
Mexico, involving a great deal of correspondence. 
In taking the census of the antelope in the United States the sur- 
vey has been fortunate in having a field organization for the control 
of predatory animals and of harmful rodents in each of the 16 States 
where the pronghorn still occurs. Their operations in these services 
are of State-wide character and are conducted in cooperation with 
the State extension services, State departments of agriculture, and 
other organizations, as well as stockmen and farmers. Their work 
puts them in touch with county agents, sheriffs, and other officials, 
hunters, and men generally familiar with the State. The State 
game officials were particularly helpful, and the field force of the 
United States Forest Service also added many facts. Without the 
contributions from these varied sources this report could not have 
been prepared. Each contributor is entitled to feel that he has
