“ Dear Sirs —I have thoroughly tested a sample of a new 
Insecticide which you were so good as to send me. At the 
rate of 1 oz. to a gallon of water at a temperature of 95° I find it 
kills Green-fly immediately. Double this strength, or 2 ozs. to 
gallon at 120°, seals the fate of Scale of all sorts in a few seconds ; 
while 3 ozs. to gallon at same temperature effectually dissolves 
Mealy Bug, and so far as I have yet observed, without the 
slightest injury to leaf or flower, and it is withal a most agree¬ 
able compound to work with. All our insect remedies are 
applied through common syringe or garden engine, a much 
severer test of efficiency than when applied by hand-washing or 
spray.

good trial in competition with many others. I am pleased to

command a good sale. (Signed) “ B. S. WILLIAMS.’
