FUMIGATION WITH CARBON BISULPHID = 275 
desirable to fumigate large bulks of grain, etc., as soon 
as possible after it is put in store. This is especially 
true of wheat, corn, peas, and beans, particularly those 
to be used for propagating purposes later. Larger 
warehouses or granaries can be successfully treated if 
the directions cited above are followed. With large 
bulks of grain the vapor may be left for two or three 
days, or even longer. 
Stimulating effects on plants.—It is an acknowledged 
fact that the growth of plants on soil following treat- 
ment is unusually good. ‘Treatment of a corn-field 
yielded an increase of 46.8 per cent. in the grain and 
21.73 per cent. in the stover. Potatoes showed an 
increase in weight, varying from 5.3 per cent. to 38.7 
per cent. Ina series of experiments upon corn, oats, 
beets, potatoes, and clover, much the same results 
were obtained, but the most marked increase was in 
the clover. It was found that the vapor was not 
detrimental to the a¢tive ba¢teria causing the nodules 
upon the roots of this legume, but rather seemed to 
favor their multiplication. Furthermore, it was found 
upon these same plats that the beneficent influence of 
the treatment was quite apparent the following year, 
though less marked than it had been the first year. 
Liffeét upon fruzt.—Recently an Italian investigator, 
M. F. Sestini, has determined the effect of carbon bi- 
sulphid upon fresh fruits. His conclusions are as fol- 
lows: One volume of carbon bisulphid evaporated in 
10,000 volumes of air produces no alteration in the 
character of the fruit during an exposure of twenty- 
four hours. After the treatment flavor is normal and
