lice reproduce so rapidly that once they become established 
it may be only a short time until the whole field is infested. 
Probably the best remedy is a preventive one, which 
consists in keeping the weeds cleared from surrounding 
fields, and the burning or plowing under of all vines and 
rubbish in the fall. Close watch should be kept early in 
the season, when hoeing and thinning, for any appearance 
of the insect. 
It is a small, green insect that attaches itself to the 
under side of the leaf. Close observation is necessary to 
discern it when it first appears. The insect secures its sus¬ 
tenance by sucking the sap from the leaf, anti only contact 
remedies, such as kerosene emulsion, will be of service. 
If but few hills are attacked, they may be destroyed, but 
this is not desirable. If the field becomes infested with this 
insect, spray the under side of the leaves thoroughly with 
the kerosene emulsion (diluted 30 times) to keep it in check. 
As soon as the melons are harvested, put in the plow with 
rolling coulter attached and turn the vines under deeply. 
Do not use the same land to grow melons the succeeding 
year.
