for any rectangular box, and if the following doses be 

 taken as correct, barrels, casks and hogsheads may be used 

 to good advantage. 



For fumigating with carbon bisulphide in a 



Hogshead use 5 oz. of the liquid 



Cask or puncheon ,, 2 oz. 

 Barrel 1 oz. 



In using carbon bisulphide, it must be remembered 

 that the fumes are very inflammable, and no h're, pipe, cigar 

 or other light should be brought near on account of the 

 danger of an explosion. The fumes are also heavier than 

 air, and consequently, the liquid to be evaporated should be 

 exposed, in a shallow dish, at the top of the room, box or 

 other container. The carbon bisulphide will evaporate, and 

 the gas descend and penetrate through all the interstices. 



If a wooden box with a cover is used as a fumigating 

 chamber, a hole in the cover, with a wad of absorbent cot- 

 ton attached below, will provide for the introduction and 

 evaporation of the insecticide, the hole being closed with a 

 cork. A blanket or tarpaulin serves well for a cover to a 

 barrel or hogshead, and a saucer or similar dish will answer 

 the purpose of a receptacle and evaporator. 



The evil smell of this insecticide will quickly disappear 

 when the fumigated articles are exposed to a free circula- 

 tion of air. 



Ants in lawns . or in garden beds may be killed by 

 tho use of carbon bisulphide, by merely pouring into the 

 principal entrance to the nest 2 or 3 oz. of the liquid, and 

 closing it with soil. All other entrances and exits should 

 be closed, and the fumes penetrating to the deepest recesses 

 and through all the galleries will completely kill out the 

 nest Nematodes and grubs may be treated in a similar 

 manner. 



Carbon bisulphide has a limited application as a garden 

 insecticide for the destruction of plant lice and similar 

 insects on low-growing plants. A box of 2 or 8 cubic feet 

 capacity makes a convenient fumigating chamber when 

 placed over an infested plant. A hole in the top of the box 

 will serve for the introduction of the insecticide, while a 

 wad of absorbent cotton on the inside of the box under the 

 hole will serve as a receptacle and evaporator. The hole 

 can be plugged with a cork,
