wet, care being taken that no more of the solution was ad¬ 
ded than was required to wet every kernel. In the soaking 
method the grain was placed in a tub, then the solution was 
added until the grain was completely covered. The mix¬ 
ture was stirred so every kernel came in contact with the 
solution and all floating kernels were removed. The grain 
was soaked different lengths of time, as shown in the table 
on page 5. 
CHARACTER OF GRAIN AND SOIL. 
In order to give the treatment a thorough test the worse 
smutted grain that could be found was used. It was so bad¬ 
ly smutted that it had been sold for hog feed and no one 
would think of planting it to raise a crop of wheat. When 
the grain was placed in the tub to be soaked the solution 
was colored black by the smut spores. 
The soil upon which the grain was planted raised a 
crop of oats the year before, and previous to that time it 
was used for a nursery. The soil was in very good condi¬ 
tion to raise grain, and it certainly did not contain any smut 
spores. 
The ground was divided into ten plats of equal size, the 
first and last plats were used as checks, being planted with 
untreated grain. All plats were seeded broadcast.

DETAILS OF EXPERIMENTS AND DISCUSSION OF RESULTS. 
The grain was treated March 14, 1902. When the 
treatment was over, all the grain excepting that treated 
with slaked lime, was spread out on the floor to dry. The 
lime and the wheat were well mixed and then placed in a 
conical shaped pile until planted. Three persons carefully 
estimated the percent of smut in the various plats. 
Plat No. 1, Was planted with untreated seed. This 
showed that the seed was extremely smutty as eighty per 
cent, of the heads were diseased.
