Prof. Greene : I think Mr. Barnes can save about four or five 

 dollars per day with compressed air. One man can spray as 

 much in that way as two men in the other way. And one man 

 can take an outfit and go out alone. The man who makes the 

 mixture can run the air-compressor. There are three men saved 

 in the work, and the three men at work will do more than six 

 men could do pumping by hand, and do it better, get a higher 

 pressure and more uniform. 



Mr. Hale : You must have a driver. 



Prof. Greene : The man who does the spraying is the driver. 

 I am speaking from our own experience. We have no trouble 

 in getting a horse that will go right along. 



Mr. Hale: How do you compress the air? 



Prof. Greene: We use a gas engine, but the steam engine 

 would be better. 



Mr. Barnes : It has seemed to me that if we could get 

 possession of some power that we could put onto our one- 

 horse outfit, the horse could soon be trained to go along, — a 

 power that would hold until that outfit came back to be refilled, 

 that would not require a first-class mechanic to be fussing over 

 the outfit all the while. 



Dr. Felt : I know such a power, but it may be just a trifle 

 expensive. Last summer, and again this winter at Geneva and 

 at Rochester, my attention has been attracted by the Niagara 

 gas-sprayer. The unique thing about it is that it depends for 

 its power upon a liquefied carbonic gas, which is superior to 

 compressed air because 3'ou have a practically uniform pressure 

 till all the gas in the cylinder is exhausted. You pay $3 a 

 cylinder ; and a cylinder, as I remember it, is sufficient to spray 

 about 600 gallons. All you have to have in addition is a tank, 

 a special tank for use in that way. It is just a question of 

 opening or closing a nozzle — no pump to get out of order. It 

 is ideal in some ways. 



Mr. Ives : Who is familiar with the matter which has come 

 to my mind ; that of a storage battery something like Edison's 

 outfit? I don't know whether it is developed or not. 



Mr. Hale : I have been studying and looking for power for 

 spraying. I have never yet found a power sprayer that con- 

 vinced me that it was as economical as man power. I believe 

 that power of some kind ought to be cheaper and better than
