HELLEBORE. 
Powdered white hellebore has been found particularly 
useful for the destruction of certain insects and may be ap- 
plied dry or in water. If applied dry it may be used pure 
or diluted a few times with flour. I prefer to use the pow- 
der pure when the slightest dusting over the leaves in the 
evening when the dew is on is usually effectual. Inclose the 
powder in a cheesecloth sack and shake it over the plants. 
If applied in water use 
Hellebore i ounce. 
Water 3 gallons. 
EXTERNAL IRRITANTS. 
It should be borne in mind that, in order to destroy an 
nsect by an external irritant, the substance must be put 
upon the insect’s body. Spraying the food will not answer.. 
KEROSENE EMULSION. 
This preparation has no equal for the destruction of in- 
sects by external contact, so far as we know at present. The 
substances of which it is composed are always obtainable 
and the emulsion is not difficult to make after one has 
learned how. PTr the ordinary strength the proportion of 
the ingredients is as follows: 
Soap I pound. 
Kerosene 2 gallons. 
Water 28 gallons. 
Prepare by dissolving the soap in a gallon of water; 
while the soapy water is boiling hot, remove from the fire 
and immediately add two gallons of kerosene and agitate 
briskly for a few minutes. If a large amount is being made, 
use a force pump and forcibly pump the mixture back into 
the receptacle that contains it until all is a frothy creamy 
mass. If such a mixture is not obtained the first time, put the 
whole back over the fire until boiling hot and then repeat 
the pumping and the emulsion will almost surely form. If 
put back for reheating watch very closely to see that it 
does not boil over and take fire. 
After the emulsion is made add the remaining 27 gal- 
lons of water and all is ready for use.
