and now that the final tests have been
 made and The plant accepted, ne feeis
 that he has found something that may
 mean a great deal To the development
 of lands without the irrigable limits of
 the various projects in the state.
 The motor is a Wisconsin" four
 cylinder type. identical with those
 which have helped to make the Stutz
 automobile famous. and depending
 upon the speed Of operation. turns out
 rom twenty to fifty-three horse power
 lt IS directly connected with a ten inch
 Northington pump. and being equipped with an Ensign carburetor tthe patent Of o. + Ensign) Is able to use santa Fc Tops for fuel Tops are now
 worth about 1c gallon in carload tanks delivered in the valley In~Spite
 of the low grade character of the fuel.
 practically no carbon Is deposited in
 the motor. for in the Ensign method of
 carburetion water Is mixed with the vapor so that air. gas and water mois-
 ture are mingled with the result that the superheated steam that is pro- duced by the contact of the water vapor with the cylinder walls cleanses the engine of carbon at each explosion. This plant Is working in cased well Of l6 inch diameter. ls5 feet deep Water Was struck at 10 feet. and the underground flow Is nov SO well developed that the total lift when run ning steadily does not exceed 35 feet. This outfit easily lifts 1900 gallons per minute. or approximately I50 miners inches. quantity sufficient for giving sixteen acres an ordinary irrigation
 .n twelve hours. lts fuel consumption [ is at the rate of 30 gallons Of tops for l. hours. and about one quart of ! ilrmiCauag oil. On most carefully prepared estimate covering total orig inai cost Of the entire plant. mainten- | ance and operation expense covering d | long period. q cost of Toe per acre fOot | Is indicated. This means that there are many places near Phoenix and in other { Arizona valleys where similar plants would prove economicaI water pro- ducers
 : Another interesting feature og this installation is the cement weir box. thirteen feet long by six feet wide and three and one-half feet deep. The water flows out over a steel knife edge weir of the Francis type and is meas l ured accurately. II is said that the | Francis weir is such satisfactory : water measuring device that Its meas urements are accepted as standard by the supreme courts of many western ! states
 ] -No fddialpT is used With the motor. { as stream of cool water flows contin-
 ually from the weir box through pipe | Into the engine jacket and then falls into the well pit. The flow Is regulated according to the speed of the engine
 and the atmospheric conditions. so that i it is easy to keep the engine tempera- | ture at the most efficient figure al any time.
 | A plant similar to this. but not Of di- 1 rect connected design was installed by Mir. Ensign on the Dr. Dysart ranch north of Glendale about sixteen months ago and this has given most satisfac-
 tory service X feature of these plants | is the lightness of the engine which
 cuts down transportation and inatal- lation figures. One of the old fashioned stationary engines of similar capacity
 would weigh i6000 pounds or over, 1g
 times as much as does the Wisconsin
 motor.
