alone will do the required work, and this requires to be thorough 
to cope with such a crevice and cranny-loving, hybernating 
insect as the Calandra. Frequent lime-washing and scrubbing 
(with soft soap) of granaries, the plastering of all uneven wall 
surfaces, the asphalting or concreting of all unlevel floors, the 
free use of the dressing machine or blower, and frequent sifting 
or turning over of the grain, are the only likely remedies against 
weevil attack. It is also necessary to guard against mixing 
sound wheat with any containing ‘‘ weevil” except for immediate 
grinding ; also to see to the destruction of all rubbish and tail 
corn in which it is possible for the beetles to live or breed. It 
was observed here during the late high tides, where corn was 
flooded, that the beetles were dispersed by the salt water; but 
this is only an accidental remedy which probably was worse than 
the disease. [ 
It is an absolute necessity that in the case of ground wheat 
great quantities of the weevil, living as it does in the corn itself, 
should enter into the composition of the flour. This is 
unpleasant at least; but it has been conjectured that their 
presence is injurious, and in other countries disease has even 
been distinctly traced to the use of flour made from weevily wheat.

The following is an analysis of the Sitophili:—An acid analogous 
to gallic acid; a substance analogous to tannin; some chyline ; 
some phosphate of lime; some phosphate of magnesia; some 
silica; various sulphates ; a peculiar animal matter; some fixed 
fatty matters ; a bitter principle; a resinous matter. 
One of my stores, containing some thousands of S. oryze, is 
kept in a closed tin, and repeatedly on opening this I have 
noticed a strong ammonia-like smell. Whether the internal 
application of ‘‘ weevil” is injurious may be questionable, but 
enough has been said to show that its destructive powers are 
enormous, and that cleanliness and care will do much towards 
diminishing its ravages.
