The atomizer, Fig. 5, of which there are many forms that are practi- 

 cally the same in construction and utility, is very useful and inexpensive. 

 For the use of the Bordeaux mixture or copper sulphate solution, it must 

 be made of brass. 



The knapsack, Fig. 7, is useful when a larger amount of shrubs or 

 small trees are to be treated and when they are too closely planted to 

 allow the barrel pump to be driven through on wheels or on a stone 

 boat. These pumps hold about five gallons and can be easily carried 

 on the back. The main objection to them is the cost which is from $12 

 to $18, complete, with hose and nozzles. 



The Barrel Pump. — This is by far the most economical and satisfactory 

 kind of a pump for general use. The pumps are mounted either on the 

 side or end of the ban-el, Figs. 8 and 9, — we prefer the former because 

 the barrel can be more easily kept in place on the stone boat or in the cart. 



It is carried about in a cart or wagon on a stone boat or on a single 

 pair of wheels, and with a piece of half-inch iron or brass pipe the tops 

 of the highest fruit trees may be reached with the spray. If tall, orna- 

 mental trees are to be sprayed the hose must -be carried up into the 

 branches and the spraying be done from there. 



Fig. 7. 



A kerosene attachment is provided on many of the barrel pumps, by 

 which kerosene and water are forced into the hose at the same time and 

 distributed from the nozzle in a fine mist or spray. As far as has been 

 tested this seems the best method of applying kerosene. In Fig. 6 is 

 shown a kerosene attachment to the pail pump. When but a small 

 amount of spraying with kerosene is to be done and only low shrubs or 

 plants, the atomizer, Fig. 5, will do the work as effectually as the more 

 expensive appliances. 



Machine Pumps. — For the varied work of the average New England 

 farmer or horticulturist, these pumps cannot be used as economically 

 as the barrel pump, but where large ai'eas of potatoes, vineyards and 

 young orchards are to be sprayed, their use may be made profitable. 

 The same may be said to a greater degree of the steam sprayers.
