MOORE: CHLORPICRIN FUMIGATION 
361 
taste from the normal, was fed to guinea pigs, rabbits, rats and cats, 
which ate it and showed no effects. 
From these results it is apparent that the chlorpicrin has an influence 
on the baking qualities of the flour. It would be inadvisable to use 
chlorpicrin on a large scale for the fumigation of flour, but there may 
be cases where its use would be advisable and where the insects would 
do more damage to the flour than the chlorpicrin. 
Effect of Fumigation on Clothing 
As no insects infesting clothing were available no data can be given 
of the action of chlorpicrin on these insects. Insects infesting clothing 
are no more difficult to kill than those infesting grain, hence chlorpic¬ 
rin should prove effective against insects in clothing if used at the 
rate of from one to two pounds per 1,000 cubic feet of space. 
An effort was made to determine if the action of chlorpicrin would 
injure different types of cloth or tend to bleach their color. The fol¬ 
lowing list of materials 1 and their colors were fumigated:
