on the subject. I am following- up the Compressed Air Sprayer and 

 am just young- in that business. If anyone has a Compressed Air 

 Sprayer, I should like to have it discussed. 



Mr. Bassett. I notice the question refers to a lo-acre orchard 

 — presumably a lo-acre bearing orchard. I have seen excellent work 

 done with a hand sprayer; but I believe that a man who has a lo- 

 acre orchard can afford a power sprayer. The nature of the sprayer 

 is open to a big line of argument. We have a gas sprayer, in which 

 the power is furnished by liquid carbonic acid gas with pressure. 

 That has been very satisfactory. The only trouble has been that 

 when we came to use the Lime Sulphur Spray, the carbonic acid 

 has broken down the solution. Gasoline engine outfits are also sat- 

 isfactory. Sometimes they get mulish ; you can't tell just what you 

 are going to get out of a gasoline engine. They have better ones 

 to-day. There are a number of good outfits on the market. As to 

 air compression, of course it is the same principle as the Niagara Gas 

 Sprayer, using compressed air, instead of gas. 



In Ohio they have a large number of power sprayers, and the 

 growers work together very nicely. They have central power sta- 

 tions, w^here a number of people go with tanks. They have two 

 tanks — one for the liquid to spray, and one to contain compressed 

 air, just the same as carrying grist to the mill. They have a power- 

 ful engine. They can buy their compressed air cheaper than they can 

 make it. You go to the central station ; there you will find a man 

 in charge, w^ho has it in readiness. You simply drive up and get 

 your compressed air. You have your other tank filled with the 

 spray material ; and you are all equipped to go to work. Where a 

 man has his own individual plant, he has a central station on his 

 own place. 



You have your engine to run your compressor, your compressor 

 to run the sprayer, and your tank to hold the spray material. The 

 one objection to a power sprayer in, an orchard, is that the machine 

 weighs considerable. When the frost is just coming out of the 

 ground, this is quite an item. You have quite a load to carry, es- 

 pecially where the engines are heavy and you have large tanks. 

 We have changed our notion as to tanks. Where we formerly had 

 250 gallon tanks, we now^ prefer tanks not over 150. We have our 

 stations not so far from our orchards, so we can go back easily. 

 This plan is a much better one than to carry such an immense load. 

 My opinion is that the power sprayer has come to stay. If men 

 want to raise fruit successfully they need a power sprayer. We 

 need more power in applying our spray materials. The proper time 

 to spray is when the blossoms stand up straight. If we stand under- 

 neath and shoot the spray upward, we are failing to hit the vital 

 point. We use elevated platforms and nozzles set at an angle to 

 the spray rod. In this way we are able to throw the spray down 

 into the calyx, taking care of fungus diseases, and also making our 

 first fight against the coddling moth. When the calyx is partly 

 closed, it is too late to try to squirt poison into it for your coddling 

 moth. We are going to use more power than we can get from a 

 hand sprayer, and we must apply our spray from above, so as to 

 get the poison into the calyx. 



Member. What pressure do you use ?
