Chittenden, of the Bureau of Entomology. Farmers are informed 
that the best remedy for such mischief is Bisulfide of Carbon, 
which may be applied in moderately tight bins by simply pouring 
the liquid into shallow pans or on bits of cotton waste and 
distributing them about on the surface of the grain. The stuff 
rapidly evaporates, and the vapor being heavier than air, 
descends and permeates the mass of grain, killing all insects, 
as well as rats and mice which it may contain. This method 
may be adopted to great advantage in elevators, which may be 
closed for the purpose over Sunday. The Bisulfide of Carbon 
is very explosive, and to breathe much of the vapor is dangerous 
to human beings, but it is perfectly safe with careful use. 
A Copy of J. C. Daniels and Co.’s Testimonial. 
We have used Bisulfide of Carbon lor three years ana nave 
found it by far the greatest aid in ridding our plant of insect pests 
that we have ever tried. It is a deadly enemy to rats, weevil or any 
breathing insect. 
While these pests may return yet a single combat in which Bi- 
sulfide is the weapon of defense is sufficient to persuade any pest 
named that ’tis better to dwell in some far off country. We regard 
it as one of the essential helps.

HANDLING WEEVILY WHEAT. 
The rapidity with which weevils breed makes it necessary 
that prompt attention be given to grain in which they are dis- 
covered. Some idea of the rate of increase may be had from 
the statements of David Hooper, curator of the Indian Museum, 
Calcutta, who has made some experiments in connection with 
the ravages of weevils in stored wheat. In the course of his 
research he found that the weevils introduced into the wheat 
at the beginning of the period had multiplied sixty times. The 
counting of an average 100 grains showed that G5 per cent, had 
been attacked by the pest, while the wheat had lost 26 per cent, 
of its weight in three months. 
While fumigation with bisulphide of carbon is the only sure 
method of exterminating weevils, it is possible to minimize 
their destructive work by handling the grain. This might 
properly be termed an emergency measure and consists in 
screening the grain on a sieve that will retain the wheat and 
allow the weevils to drop through, at the same time subjecting 
the grain to a strong air blast, which will lift out the insects. 
The principal objection to this method is that it fails to 
destroy the eggs or larvae in the wheat grains. These can only 
be reached by the proper application of bisulphide of carbon. 
While the latter may be poured or sprayed over the infested 
grain, the best results are obtained by allowing the liquid to 
evaporate and the fumes to penetrate the grain. The bins in which 
the grain is treated should be fairly tight and the bisulphide of 
carbon should be placed in shallow pans on the top of the grain. 
The liquid volatilizes rapidly and, being heavier than the air. 
sinks down into the grain, killing all insects and vermin present. 
It should be remembered that the bisulphide is highly in- 
flammable and no fire of any kind should be allowed in the mill 
until the fumes have entirely passed away. — American Miller, 
December, 1907.
