FOR BETTER CROPS 



Insects Killed by Evaporation of Liquid — The liquid rap- 

 idly volatilizes and being heavier than air, descends and perme- 

 ates the mass of grain, killing all insects and other vermin 

 present. 



The bisulphide is usually evaporated in vessels containing 

 one-fourth or one-half pound each, and is applied at the rate of 

 a pound and a half to the ton of grain. In more open bins a 

 larger quantity is used. For smaller masses of grain or other 

 material an ounce is evaporated to every 100 pounds of infested 

 matter. 



The grain is generally subjected to the bisulphide treament 

 for twenty-four hours, but may be exposed much longer without 

 harmful results. Since this chemical is inflammable, all lights 

 and matches should be kept away from it. 



A familiar scene at harvest time 



The time will surely come when grain will be sold for the 

 cleaned grain, and then all the farmers will be induced to keep 

 the weed seeds and other foreign matter to be fed to live stock 

 on the farm where they were raised. 



During recent years great improvements have been made in 

 grain cleaning machinery, both in the threshing separator and 

 In the barn fanning mill. With one of the modern fanning or 

 grading mills, which is both efficient and rapid, the grain can be 

 re-cleaned before sale at no great cost of labor. As a matter of 

 fact, many threshing separators in good hands put only clean 

 grain into the farmers' granaries. 



The Most Profitable Marketing of Small Grains — It pays 

 to market some small grains "on lioof;" that is, feed them to 

 live stock ; but the larger part must go to feed the men and 

 horses of the cities, and to make linseed oil and other non-food 

 .products.
