the Spray-pump tliis yenv, aggregating three hundred acres, 

 is an object lesson tliat should convince those who do not 

 spray that they cannot afford to ignore the facts of these 

 growers" success in fighting tlie apple worm. Then, those 

 Avho have sprayed, and not had tlie success desired, should 

 investigate and see where their mistakes occurred, and remedy 

 them, for they have made mistakes either in the remedies 

 used or in their methods of spraying. I assert, from per- 

 sonal knowledge, that the yearly damage of the apple worm 

 can be successfully combated by an intelligent use of the 

 spray-pump, and the remedies recommended by the State 

 Board, and at an annual cost not to exceed tAvo cents for 

 every box of sound apples. 



(fASOMXE POWER IN SPRAYTN(;. 



This year Olwell Brothers, of Central Point, used a gasoline 

 engine of two horsepower to run their spray-pump. Last 

 year they used four spraying rigs, with a force of twelve men, 

 to run them in their orchard of one hundred and sixty acres. 

 This year they did the same work with four men and two 

 teams with their gasoline engine, saving the expense of two 

 teams and eight men. One team hauls the engine, pump, 

 and tank of one hundred and twenty gallons capacity, with 

 three men, one to drive and two hold the sj)raying nozzles. 

 The man who drives the team observes from his point of 

 vantage that the nozzlemen direct the spray to all parts of the 

 tree, which assurs thoroughness. One team and man, with 

 water tank on his wagon, hauls water to the spraying tank. 

 The water is transferred to the spraying tank in a moment by 

 a pump attached to, and run by, the engine. At the same time 

 four and one-half ounces paris green and four and one-half 

 ounces london purple and lime are put in, and the spraying- 

 pump and agitator is thrown in gear, and spraying at once 

 begins. The loss of time in filling the spraying tank from 

 the tender is very small, as everything about the transfer is 

 done very quickly. The agitator on the spraying tank is 

 geared to a bevel wheel, and run by a small shaft and pinion, 

 a.nd the poison at all times is kept in solution. Olwell 

 Brothers are much pleased with gasoline power in spraying, 

 on account of economy and their ability to do the work well. 

 Weeks & Orr, of Medford, will use gasoline power next year, 

 and, as gasoline power is better understood, and its adapta-
