In Table. XI it is shown that the average yield of spring 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. 



Though wheat is by far the most important crop at Nephi, some 

 work has been done with oat varieties. From the results obtained, 

 no variety has proved to be financially profitable. Spring oats 

 have suffered from the drought of summer, and whiter oats have 

 suffered from winterkilling. It is believed, however, that winter 

 varieties will prove hi 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 < >ats. ' 



Only one variety of winter oata lias 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 a sack marked 

 ed 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
