through the seed and rises as it drives the air out. It has also 

 great penetrative power, and any products contained in bags, such 

 as beans, rice, corn, flour and grains when infested, can be placed 

 in tight compartments and fumigated successfully. 



Carbon bisulphide is a very explosive liquid and can be placed 

 on a par with gasoline. It is therefore very necessary to keep it 

 away from fire. There must therefore be no smoking or carrying 

 around of lights when fumigation is being done, nor should any 

 electric current for light or fans be present, as the spark will 

 ignite the vapor and cause an explosion. With these precautions 

 anyone can use the liquid and obtain success. 



The small farmer can construct his small fumigating box or 

 if he has a good tight wine barrel he can use that. The larger 

 producer can build a permanent structure of concrete which is 

 by far the best, or if not out of T. and G. lumber, the walls, floor 

 and roof made double with building paper between. The door 

 should have beveled edges and should match well into the frame. 



Bisulphide of carbon is a colorless liquid with a very offensive 

 odor, locally known as "highlife" and is very volatile. When 

 applying it for fumigating of stored grains or other materials it 

 is used at the rate of one pound to 1000 cubic feet. The liquid 

 should be poured into shallow pans, as the quicker it evaporates 

 the better the results will be from the vapor. The pans should be 

 placed on top of the grain to be fumigated, as the vapor being 

 heavier than air will descend to the bottom of the room and 

 gradually rise and fill the compartment. All material should be 

 left in the fumigating room or box for at least 24 hours or, better, 

 48 hours. The vapor is very penetrating but when the grain, 

 beans, corn and other foodstuffs are in bags a longer time is neces- 

 sary to allow the vapor to reach every space. The bags should be 

 carefully piled, especially when a large quantity is to be fumigat- 

 ed. Care should be taken to allow plenty of air space between 

 them so that the vapor can readily reach each bag. When milled 

 grain, like flour, middlings and other products have to be fumigat- 

 ed, owing to the density of these products, double the quantity of 

 carbon-bisulphide should be used. 



Summary. 



It is absolutely necessary to have a tight box, barrel or room 

 for fumigation. 



If grain is in bags, the bags should be so placed as to allow 

 free access of the vapor of carbon-bisulphide to all parts as near 

 as possible. 



Shallow pans should be used for the liquid and should be 

 placed at the top of the pile to be fumigated. 



From one to two pounds of carbon-bisulphide should be used 

 for every 1000 cubic feet according to the density of the product 

 to be fumigated, and should be subjected to the vapor for at least 

 24 hours, longer if possible.
