It can be erected in a few hours, and may be relied 
upon as a thoroughly sound and good Hot-water

possible way, more especially with regard to power 
and durability, and the result has been highly 
satisfactory. 
In the event of a Pipe in this Boiler requiring to 
be replaced, an arrangement has been perfected 
whereby the same may be made in the course of a 
FEW MINUTES, without the necessity of dis¬ 
turbing the brickwork setting.

“ 15, Princes Street, Edinburgh, 15th July, 18S7. 
“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-wasliing or 
spray. 
“ I remain, Dear Sirs, yours truly (signed) A. MACKENZIE.”

London, 7th January, 1888. 
“Gentlemen —I have given your Insecticide, ‘ Picrena,' a 
good trial in competition with many others. I am pleased to 
say that I have found it more effectual in destroying Mealy Bug 
and other insects than anything we have used. It ought to 
command a good sale. (Signed) “ B. S. WILLIAMS."
