45 



inch gas pipe ten feet long, with hose coupling at each end, was used. 

 If the Vermoiel nozzle with the spray coming out on one side is used 

 the pipe need not be bent, but if any of the adjustable straiuht 

 nozzles be used the pipe should be bent, at the end, to an angle of 

 about 45''.

The Knapsack pump, Fig. 2, was found very useful where only 

 a few small trees or vines were to be sprayed. A piece of tliree- 

 eighths inch brass or iron pipe, six feet long with hose couplings 

 attached, was found very useful in many cases. 



The Hydrosprayer, recommended by Dr. Fisher, made by Robt. 

 T. Deakin & Co., Philadelphia, Pa., Fig. 3, is a very useful instru- 

 ment for applying clear liquids, but is not adapted to the use of the 

 Bordeaux mixture. Any of the small garden or carriage pumps like 

 Fig. ^4 will answer for this work, if only a few vines or small trees 

 are to be sprayed.
