warehouses, and stores where grains, flour, or any food stuffs are kept 
a thorough annual cleaning, followed by an application of bisulphid 
sometime in early spring. Much if not all this insect injury would 
thus be avoided and the purity and cleanliness of food materials 
would be more fully insured. 
EFFECT OF THE VAPOR UPON FRUIT. 
It has already been stated that the vapor of carbon bisulphid acts 
as a powerful disinfectant, having the power to preserve meats 
unchanged for a considerable time. Very recently an Italian, M. F, 
Sestini, has experimented to determine its effect upon fresh fruits. 
The substance of his.conclusions is as follows: 
1. One volume of carbon bisulphid evaporated in 10,000 volumes of air produces 
no alteration in the character of the fruit during an exposure lasting twenty-four 
hours. After the treatment flavoris normal and it appears that the perfume of each 
fruit gains in fineness and intensity. 
2. With this dose of carbon bisulphid all the common insects are easily killed in 
one hour. 
3. Under these same conditions the color of the fruits which are not entirely sound 
becomes deeper, especially upon those parts of their surfaces which have suffered 
bruises during ripening or from defects in packing; it is thus very easy to choose 
carefully, rejecting such fruit as could not have been preserved.
