Plat C was irrigated in the same manner twice, once at the 

 same period in the plants' growth as in Flat B and again just 

 after the grain set. 



All plats, then, received the rainfall of the season and Plat B

 the last one very late in its period of growth. 



The wheats used in the experiment and their original com-

The grains were seeded on December 7. They all came up 

 with a good stand on December 28-31 and were harvested in 

 two lots on June 24 and 30. there being but one or two days

 non-irrigated plats. 



The analysis of the several lots gro\vn on each plat is shown 

 in the following table:
