same company on Hackers Creek. The equipment includes 

 three 450 horse-power Snow single tandem gas engines, with 

 cylinders 20"x36" and compressors 18^"x36", the plant be- 

 ing designed to add a fourth unit of the same size, making a 

 total of 1800 horse-power. The suction pressure is 50 pounds, 

 and discharge pressure 150 pounds, the suction temperature 

 being 50 Fahrenheit, discharge temperature at engine, 200, 

 and discharge into line ahead of cooler, 55. The cooling de- 

 vice consists of 4 header pipes with seven joints of 4" pipe 

 extending from each header through which the gas is passed 

 while water is sprayed over the entire group in a manner simi- 

 lar to ammonia cooling systems, the device being one that is 

 employed at only one other pumping plant in the State, but 

 has been used in California. 



The auxiliary plant contains one Bruce McBeth 40 H. P. 

 gas engine, direct connected with a General Electric 125 voli, 

 240 ampere D. C. Generator for lighting and auxiliary pump ; 

 one 10 H. P. motor, driving a twin cylinder Clayton air com- 

 pressor which produces 125 pounds of pressure for starting 

 the large engines ; one 10 H. P. motor to drive the auxiliary 

 pump; 3 sets of 150 ampere hour storage cells, 5 cells to the 

 battery, for ignition service for pumping engines ; one 4 cell 

 battery for auxiliary ignition, used only for starting the auxili- 

 ary engine or for an emergency ; one 9/10 K. W. Peerless 

 generator set used to charge storage cells ; one 3 panel switch- 

 board with mercury mountings. 



Each large engine pumps its own water, the auxiliary 

 plant being run only at night for lighting and charging storage 

 cells. The entire plant is heated by a closed coil hot water 

 system that obtains its hot water from the engine exhausts 

 where no cold water is used to cool the exhaust gases except in 

 summer, when the heating plant is not needed, and when it is 

 cut out with a by-pass. The plant uses 10 cubic feet of gas per 

 horse-power hour. 



There is a large group of wells along Polk Creek, a few 

 miles west of Weston, a few of which produced oil, but most 

 of them being gassers. The seven following records are from 

 this vicinity :
