1020 ANNUAL. REPORT OF THE Off. Doc. 



KEROSENE EMULSION. 



Parts. Per bbl. 



Hard soap (shaved fine), ^ fb. 1 lb. 



Water, 1 gal. 2 gals. 



Kerosene, 2 gals. 3^ gals. 



Dissolve the soap in the water, which should be boiling, and while 

 it is very hot pour the suds into the kerosene; then churn it with a 

 spray pump till it changes to a creamy mass, and then to a soft, but- 

 ter-like substance. This should keep for some time. When it is 

 desired to use it, add one quart of it to nine times as much water, 

 mix well, and spray the plants. The water should be soft water, or 

 else have some soda added to it. 



For the Four-lined Leaf bug take one part of the Emulsion and 

 five parts of water. 



TOBACCO WATER. 



Place tobacco stems or refuse tobacco in enough hot water to 

 cover; let stand several hours. Take one part of this to three or 

 four of water, and spray over the plants. 



CARBON BISULPHIDE. 



To be obtained of druggists at about thirty cents per pound. In 

 using, avoid bringing it near fire or even hot steam pipes, as it 

 catches fire easily. Avoid breathing it also. 



HELLEBORE. 



May be applied either as a powder or in water. If used as a 

 powder it may advantageously be mixed with an equal amount of 

 flour, which causes it to remain better on the leaves. For use with 

 water one ounce of fresh Hellebore is mixed with three gallons of 

 water. 



INSECT POWDER. 



Insect powder is sometimes sold under the names of Pyrethrum 

 and Bubach. It may be applied as the dry powder, when the plant 

 i« wet with dew. It may also be mixed with flour and used in that 

 way, or it may be used in an alcoholic solution as follows: 



Insect powder (by weight), 1 part. 



Alcohol (by weight), 4 parts. 



Put the two in a tight vessel and leave there for eight days, 

 shaking it occasionally; then filter and spray over the plants.
