The few data presented in Table XLVI indicate that. there is little 

 choice between the early yellow and the midseason white varieties for 

 growing in the Palouse district of eastern Washington. The average 

 yields of the varieties in the two groups are about the same. 



RESULTS AT fUYALLUP. 



The average yields of the Sixty-Day and eight other varieties of 

 oats grown from spring seeding at the Western Washington Agri- 

 cultural Experiment Station at Puyallup (40, p. 11-12) in the 3-year 

 period from 1914 to 1916, inclusive, are shown in Table XL VII.

It is realized that the data contained in Table XLVII are too 

 meager to be conclusive. However, they indicate that the best 

 midseason varieties probably will outyield the Sixty-Day under 

 western Washington conditions. The high rainfall and compara- 

 tively cool growing season of the Puget Sound district naturally 

 favor the larger midseason varieties. 



Results in California.! 



The Sixty-Day oat has been included in the cooperative varietal 

 experiments at the Plant Introduction Garden at Chico, Calif., since 



' Data from unpublished annual reports of Mr. E. L. Adams, formerly assistant agronomist in charge of 

 cereal experiments at the Plant Introduction Garden, to the Office of Cereal Investigations.
