Comparative stand of winter wheats. — As used here, "stand" means 

 the number of thousands of plants to the acre which have survived 

 the winter and actually grown on the plats. This was determined 

 in the following way: A light metal frame 3.3 feet square, con- 

 taining 1/4,000 of an acre, was used to inclose the areas in which the 

 plants were actually counted. On plats that had reasonably uniform 

 stands, four areas, chosen at random but fairly representative of the 

 entire plat, were selected and the plants hi them counted. The total 

 number of plants found on the four areas equaling 1/1,000 of an acre 

 is the number of thousands of plants per acre. Where the plats 

 were unusually lacking in uniformity, more than four areas were 

 counted, and the number of plants per acre calculated accordingly. 



There was found to be a wide variation in the average number of 

 plants per acre for all varieties in different years. An exceptionally 

 severe winter would result in considerable winterkilling (affecting 

 some varieties more than others) , and this invariably would result in 

 low yields. There seems to have been no correlation, however, 

 between the stand and the yield of the varieties. In many cases 

 there would seem to be a direct relationship between stand and
