{See Fig. 13.) 



The Challenge is specially adapted for small orchards ; is very 

 strong, powerful, simple, and compact. It is fitted with lever and

 removed; it cannot get out of order, and any person can repack it, thus 

 saving any cost for repairs. It can be detached and packed in a small 

 space for transit.

Unsworth's Patent Sprat Pump. 



{See Fig. 14.) 



A new departure in Spray Pumps. — The pump requires no attention 

 during spraying when once the air chamber is pumped full, and will, 

 with an ordinary jet, keep up a continuous spray for ten minutes. It 

 consists of two cylinders, one over the other, the top cylinder being 

 air-tight, in which the liquid from the bottom cylinder (or tank) is 

 pumped ; thus, having a large air pressure, an even and continuous spray 

 is kept up. A boy could manage it. 



Made in galvanized ironor copper, with gun-metal valves. 



Price : Without sledge, in galvanized iron, £5 ; in copper, with 

 wood tank, £6 10s. ; holds 15 gallons. Larger sizes to order.
