bushel and gave a moisture test of eleven and nine-tenths per cent and a 
germination test of 91%. 
A glass jar holding about one-half bushel was filled level full of wheat 
taken from the mill. A rubber hose was passed from the chlorine tank 
to the bottom of the jar. The gas was allowed to run into the jar 
until the presence of the gas was decidedly noticeable at the top. Time 
required was 28 minutes. Eight samples were taken at intervals of 
five, ten, fifteen, thirty, and sixty minutes, three hours, four hours and 
twenty-two hours. After removal from the fumatorium the samples 
were aerated by pouring from one vessel to another several times in the 
presence of a breeze. 
An attempt was made to repeat the operation, using the wheat taken 
from the thrashing machine the previous day. The gas was turned 
on and strips of paper saturated with ammonium hydroxide were placed 
as indicators on the top of the grain. After the flow has continued about 
one hour no chlorine could be detected at the top of the jar. but the jar 
was quite warm, on the sides near the bottom. The gas was at once shut 
off. Upon examination the wheat in the bottom of the jar was found 
completely charred and there was a distinct odor of hydrochloric acid. 
(The jar was undisturbed for a few hours and then examined. The 
wheat was entirely ruined). 
Control in first lot. 
The samples taken were placed in a dark, warm cupboard. On 
January 2nd, 1923, the five, ten and fifteen minute samples contained 
living moths. Moths continued to emerge from these samples. On 
January 29th all the samples contained some living moths. 
Effect on germination. 
Check sample gave a germination of.91% 
Five minute sample gave a germination of.26.5% 
Ten minute sample gave a germination of.29.5% 
Fifteen minute sample gave a germination of.17.0% 
Thirty minute sample gave a germination of.16.5% 
vSixty minute sample gave a germination of.12.5% 
Three hour sample gave a germination of. 7. % 
Four hour sample gave a germiniation of.11.5% 
Tw r enty-two hour sample gave a germination of.10.5%
