A o-ood, strong double-acting force pnmp should be purchased and 

 mounted on a large stout barrel with the supply tube reaching well dow^n 

 to the bottom. It has become the custom to mount the pump in the end 

 of the l)arrel, but except in the case of the Nixon Tripod, it will be al- 

 most as easy to mount it on the side of the Imrrel, which is easily held in 

 place by a skid near either end, and is then more compact and stable 

 than when standing on the end, while the handle of the pump comes 

 lower and is more easily worked. 



It will be well to buy the pump without attachments. About 25 

 feet of i inch cloth insertion rubber tubing is attached to the discharo-e 

 orifice, or to each of the orifices in case there are two. To the end of the 

 tube is fitted one of the modifications of the Cyclone or Kiley nozzle and 

 the outer 8 or 10 feet are clamped or wired to a light pole or bamboo fishino- 

 rod for convenience in elevating the nozzle into the larger trees. The 

 tank or barrel is mounted on a cart or sled and driven between the tree 

 rows, one man driving and pumping acd the other holding and directing 

 the extension pole and nozzle. 



I have mentioned the cyclone nozzle for the reason that, all things 



some of its modifications, to 

 be the best for orchard work. 

 The Climax nozzle manufact- 

 ured and sold by the Nixon 

 Nozzle & Machine Co. is also 

 a good nozzle, but it is rather 

 large and clumsy, its sprav 

 hardly so fine, and it will not 

 answer for fungicides contain- 

 ing lime, since it clogs easilv. 

 The Vermorel modification of 

 the Cyclone nozzle (Fig. 2) pos- 

 sesses a little attachment which 

 quickly un clogs the orifice 

 when once stopjied up, and is 

 therefore preferable. More-

over, neither the Cyclone nor the Vermorel modification is patented, 

 which other things being equal, is in their favor. Both are nianufact-
