376 Report of the Horticultural Department of the 



Fairbanks-Morse engine used in the Goulds' gasoline outfit and 

 shown in Fig. 42. 



As an example of the horizontal engine the one used in the Lunt- 

 Moss outfit may be instanced. (See Fig. 43.) This one is fed by 

 pumping the gasoline from the base to the mixing chamber and has 

 a governor to regulate the speed when the load varies. It is built on 

 the four-cycle plan. One of these engines has been in use in an out- 

 fit at the Geneva Experiment Station this past summer. (See Fig. 

 44.) The engine is mounted behind a horizontal tank and on the 

 same platform. It is entirely enclosed on sides and top^in the case 

 of our outfit with canvas — to prevent any of the spray mixture falling 

 on the engine. In our outfit the flaps of canvas are held down with 

 snaps, admitting of ready access to the engine. The tank has a 

 capacity of 250 gallons. The tower is readily removable by with- 

 drawing four bolts, making the outfit handier for use among low 

 trees. With the tower removed the top of the tank itself may be 

 used as a spraying platform. 



The Friend Mfg. Co. is putting out a gravity-feed horizontal engine 

 regulated by sparking. It has direct connection with a Friend hori- 

 ?ontal pump. Fngine and pump are on a common base. 



Our present opinion is that engines equipped with governors to 

 regulate speed and fed by pumping from base to mixing chamber 

 are probably better adapted to spraying purposes than those without 

 governors and with gravity feed. 



There has been so little practical field experience with gasoline 

 engines in spraying operations that it is not practicable to make 

 statements as to the relative merits of different makes. The follow- 

 ing list includes all the manufacturers we know of who offer gasoline 

 engines especially for use in spraying operations : 



E. C. Brown & Co., Rochester, N. Y. 

 The Deming Co., Salem, Ohio. 

 Field Force Pump Co., Elmira, N. Y.
