UPPER GROUND ST., BLACKFRIARS, S.E. (Telegraphic Address—HOTWA TER, LONDON. Telephone—No. 4763), 
Have now pleasure in bringing to the notice of Horticulturists and Gardeners generally 
THE CHAMPION HORIZONTAL TUBULAR BOILER (S) 
WHICH IS WITHOUT DOUBT THE BEST ALL-BOUND BOILEB IN THE MARKET.

It combines all the advantages of its class so well 
known, and by the improved method of forming the 
joints—viz., with India Rubber Washers, THE 
OLD AND TOO OFTEN INEFFECTUAL WAY 
OF CAULKING THE JOINTS IS ENTIRELY 
DISPENSED WITH. 
It can be erected in a few hours, and may be relied 
upon as a thoroughly sound and good Hot-water 
Generator. It has been carefully tested in every 
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 , 1S87. 
11 Dear Sirs —I have thoroughly tested a sample of a new 
Insecticide which you were so good as to send me. At. the 
r>te 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.

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