2 BULLETIN 1394, U. S. DEPARTMENT OF AGRICULTURE 
furnished by one man, G. A. Christensen, of Redmond, Utah. 
All animals have been of native stock, raised in the general neighbor- 
hood of Salina. Their ages have varied from calves to 3 years or 
more, though most of them have been yearlings and 2-year-olds. 
In this general portion of Utah cattle are run on the higher ranges 
during summer months, and in the winter are kept in the valleys, 
most of them being held in pastures and fed during periods of bad 
feather. During the winter months no attempt is made to fatten 
animals which are to go on the range again the following summer. 
Naturally these cattle are not always in the best condition in the 
spring, though very few of them are particularly poor. 
Though cattle are kept at the Salina experiment station primarily 
for use in the experimental work with stock-poisoning plants, each 
year there have been a number not used in the experimental feedings.

-Average gains in weight made by cattle kept in pasture at Salina experiment station, 
Utah, during summers of 1916, 1917, 1918, and 1919 
These animals were kept in one of the pastures and not disturbed 
except to bring them in to the corrals at intervals to weigh them. 
During the first years these weighings were not made at stated 
intervals; but, in 1919 and the following summers, attempts were 
made to weigh them on Saturday of each week. This has been 
accomplished with fair success. Inability to find certain animals 
at times and the fact that some have broken out of the pastures at 
intervals have interfered somewhat with the regularity of the weigh- 
ings, but have in no way affected the general results. 
In the average season, at the Salina experiment station, some snow 
remains until about the first of June; it is fully as late as that before 
the vegetation starts. The cattle are, therefore, obtained as soon 
as the pastures can furnish them with forage. By the end of Sep- 
tember, vegetation has been killed by the frosts and has largely 
dried up. Governed by the season, the station at Salina is usually 
opened the first of June and closed the first of October.
