A UNIQUE WYOMING WATER MOTOR.

of piles, plank and loose stone, was built, extending tion of an undershot and breast wheel. The thirty 



at an angle of almost 20 degrees towards the shore 

 for 50 feet, and then for 12 feet directly down the 

 stream parallel with the shore. A similar wing dam 

 was constructed from the shore, the' two forming a 





letter Y, with the stem extending down stream. The 

 main current of the stream passes over the low dam, 

 but a side current is directed by it into the Y where 

 the water wheel is placed. The wheel is a combina- 



inches of fall which the river makes in the riffle is 

 concentrated in the shute carrying the water 

 through the Y. With a 10-foot diameter wheel, 

 14 feet long, 60 horse power is secured. This in 

 the Harvey plant is used at the present time 

 to run a 3^-inch centrifugal pump which raises 1,000 

 gallons of water per minute a height of 16 feet. The 



same power will run a 5-inch pump, raising 7,000 

 gallons per minute. The wheel is hung on a swing- 

 ing frame and is balanced by a counter weight. Its 

 gearing is a sprocket wheel so that it can be raised 

 or lowered with the varying rise or fall of the river 

 without any readjustment of gearing. Logs have 

 been run under it and it has ridden over them like a
