a On dry basis. 
From the data obtained, it is very evident that the normal physiology 
of the plants was changed considerably on the different plats. This is 
shown both by observations on the morphology of the plants and by 
chemical analysis, but these changes apparently affected stem rust only 
indirectly by affecting density of stand and time of ripening. 
RESULTS FROM THIRD SERIES—ANOKA 
The third series was laid out on a light, loamy sand near Anoka, Minn. 
The plan of the plats was similar to that of the second series, both in 
disposition of the plats and in the application of fertilizers. The full square 
rod was sown to the one variety, Marquis, instead of two varieties as in 
the preceding experiments. The disposition of the plats, the rate and

division of agricultural biochemistry of the University of Minnesota.
