KEEPING WEEVILS OUT OF GRAIN. 
E. Duntor, Nobby.—The only cheap and perfect means for the 
prevention of weevil upon grain consists in the employment of 
bi-sulphide of carbon. The quantity required, provided the grain is 
kept in close vessels, is very small—not more that 13 lb. to each 
ton of grain—so that the cost of preserving a ton of wheat is 
under 1s. ‘The bi-sulphide leaves no disagreeable taste or smell 
behind, and the quality of the grain remains unimpaired. When 
bags are used instead of iron tanks the protective influence of the 
chemical soon ceases, and a fresh application must be made. In 
either case, the liquid is applied as follows :— 
A ball of tow is tied to a stick of such a length that it can just 
be plunged into the middle of the receptacle holding the grain. 
The tow receives the charge of bi-sulphide like a sponge, and is then 
at once plunged into the sack, or tank, and left there, the mouth 
being closed tightly. When necessary the stick may be withdrawn, 
and the charge, which is 1 oz. bi-sulphide to 100 Ib. grain, renewed. 
There is no need to first expel the air from the tank.

COOLING CHAMBER FOR A DAIRY. 
Darryman, Geeham.—The construction of a cooling chamber without the 
adjunct of a refrigerating plant has often been tried, but without, 
any really good results. The simplest method of cooling is by the 
use of large water-bags, or by building a chamber with insulated 
walls. In the January (1992) issue of the Journal we illustrated 
an. article by Mr. G. Monks, One-mile, Gympie, on the subject of 
artificial cold, and the construction of a simple cold chamber. We 
would advise our correspondent to communicate with Mr. Monks, 
who will doubtless willingly give all information on the subject.
