In Table XI it is shown that the average yield of sprmg wheats 
for the past five years has been very low. In comparison with that 
of the winter wheats, which have average yields of 17 to 23 bushels 
per acre; the spring wheats have been very unprofitable. The 
durum varieties have yielded more uniformly from year to year 
than have the common varieties, but the average yield of the latter 
is a little in excess of that of the durums. 
OATS. 
Though wheat is by far the most important crop at Nephi, some 
work has been done with oat varieties. From the results obtaimed, 
no variety has proved to be financially profitable. Spring oats 
have suffered from the drought of summer, and winter oats have 
suffered from winterkilling. It is believed, however, that winter 
varieties will prove in the end to be the most profitable ones, because 
the climatic conditions in the Intermountain States are unfavorable 
for the growth of spring cereals in general. 
WINTER Oats. 
Only one variety of winter oats has been tested at the substation, 
viz, the Boswell Winter (C. I. No. 480), a black oat. Mr. Stephen 
Boswell, of Nephi, Utah, received a small quantity of seed of this 
oat from a friend in England who secured it from asack marked 
“‘Seed oats,’ which stood on a wharf at Liverpool. Mr. Boswell 
planted the seed in his garden in the fall and was surprised to find 
that several plants survived the winter. The seed of these plants 
was saved and planted in the fall of that year. Again there was a
