 M. VEBMOUEL'S KNAPSACK PUMP ECLAIR.'' 



without re-charging, and is well adapted for bush and young standard trees up to h 

 height of 10 feet. For tall trees the delivery pipe or hose can be lengthened, and the 



latter with nozzle attached raised by a light cane 

 or stick. This necessitates the help of a boy. 

 Ordinarily, one man can use the machine. 



Mr. C. Lee Campbell lias found a machine 

 manufactured by Messrs. Boulton & Paul, Nor- 

 wich, very serviceable in his plantation of about 

 6,000 trees. The machine is an ordinary water- 

 barrel, holding about 3G gallons, mounted on 

 broad wheels and drawn by hand. A powerful 

 pump fixed at the rear end of the barrel, with 

 two delivery hose-pipes attached, which may be 

 lengthened to any necessary extent, will spray to 

 a height of 30 to 40 feet. "Three men go with 

 the apparatus, two men to spray and one to pump. Should the wind, however, be 

 rough, we cannot always use two sprayers. The two sprayers assist in drawing the 

 barrel. The rapidity of spraying necessarily depends somewhat on the wind, because 

 as the spray is effective at least 50 feet in quiet weather, it follows that in bad 

 weather we arc reduced to operate on a small area. I am able to spray 3,000 treea 

 a day under ordinary circumstances. . . . Messrs. Boultou & Paul, at my suggestion, 

 have arranged the pump so that with every movement of the handle the dashers are 

 agitating the liquid. Stott's double sprayer, fixed to 

 the end of the tubes, works admirably, and economises 

 the liquid immensely, besides rendering it less needful 

 for the men's hands to be constantly wet.-' (Fourteenth

 Hemingway's American force-pump is adaptable; for 



fixing on a water barrel or to be fed from a cask or pail. 

 It delivers a dense spray, so that a large tree may be 

 covered in one minute. When furnished with two out- 

 lets, one can be turned into the vessel, thus keeping the 

 contents completely mixed. This is a capital spraying machine for large orchards and 

 plantations.
