valve operated by the governor as shown in the sec- 

 tional view. Thus the amount of the fuel is regulated 

 according to the load conditions without any adjust- 

 ment by operator. 



The small jet of fuel striking the inrushing air 



is as thoroughly vaporized as a gasoline carburetor 

 vaporizes gasoline, consequently the Lauson Kerosene 

 Engine gives full rated horse-power on kerosene, the 

 same as it does on gasoline. 



Through a separate opening water is automatically 

 drawn into the cylinder on heavy load to prevent ex- 

 treme temperature, which also improves the lubricating 

 conditions and makes a smooth, quiet running engine 

 when carrying heavy load. 



One of the greatest drawbacks to any engine 

 operating on kerosene, distillate or other low grade 

 fuels has always been the diluting effect of the kero- 

 sene upon the lubricating oil, as any of the cheap fuels, 

 if not perfectly vaporized, will mix readily with the 

 lubricating oil and destroy its lubricating qualities, 

 thereby causing the formation of carbon and excessive 

 wear on the cylinder, piston and rings. 



When an engine does not thoroughly vaporize the 

 fuel it can be detected at once by the most inexperi- 

 enced layman as all of the liquid fuel will not burn 

 during the combustion and some of it will pass through 

 the exhaust pipe in the form of vapor or white smoke. 



A Lauson Kerosene Engine will operate without 

 smoke on all loads, and it is for this reason that they 

 use less than one pint of fuel per horse-power hour and 

 give years of service with the lowest possible cost of 

 up-keep. The Lauson Kerosene Engine is necessarily 

 of throttling governor type in order to maintain a 

 uniform temperature at all times. They run as steady 



as a steam engine and are especially adaptable for fac- 

 tory power purposes, mills, elevators, irrigation, pump- 

 ing plants, city pumping plants and wherever smooth, 

 steady power is required. 



Built in sizes from 2y> to 100 horse-power in the 

 stationary tank cooled types ; 2^ to 28 horse-power in 

 the hopper cooled, either stationary or mounted on, steel 

 skids and in the portable type in sizes from 3J/2 to 28 

 horse-power, either hopper or tank cooled. (Adver- 

 tisement.) 



LETTERS FROM OUR READERS 



Fallen, Nevada, May 31, 1916. 

 THE IRRIGATION AGE : 



Dear Sir: Enclosed you will find money 

 order for $2.00, which will set me up to February, 

 1917. Much obliged to you for kindness received. 

 I think your publication is doing a fine and much 

 needed work. Very respectfully,

ADJUSTING IDAHO'S WATER RIGHTS 



The Boise, Idaho, Maintenance and Operative 

 Conference, at an important meeting held early 

 thi syear at Boise, took determined action in favor 

 of a readjustment of water right conditions in that 

 state. 



The resolutions passed at the closing session of 

 the conference are as follows : 



"Resolved, it is the sense of this conference that 

 the next session of the legislature of the state of 

 Idaho be requested to enact the necessary legisla- 

 tion to constitute what shall be known as a state 

 water commission or board of control, which shall 

 have authority to administer the public waters of 

 the state. 



"This board shall be constituted of three mem- 

 bers, one of whom shall be the state engineer, and he 

 shall be the chairman of the board. 



"The two other members shall be appointed by 

 the governor for a term of six years, except that in 

 the initial appointment one shall be for only three 

 years. 



"This board shall have entire control and au- 

 thority over the appropriation and use of the waters 

 of the state, and it shall be empowered to adjudicate 

 said waters and fix the duty of the same. 



"It is further recommended that an amendment 

 to the constitution of the state be submitted to the 

 voters, to the effect that no water right can be ac- 

 quired except by obtaining a permit from the office 

 of the state engineer, and subject to the approval of 

 the said board. 



"Recognizing the immense value of the water 

 supply of the state of Idaho, and realizing the pres- 

 ent inadequacy of dependable data concerning the 

 same, it is hereby resolved that it is the sense of 

 this conference that the imperative necessity for 

 taking steps to acquire this information be brought 

 to the attention of the governor and the next state 

 legislature and that an annual and sufficient appro- 

 priation from the state treasury for co-operation 

 with the United States Geological Survey is hereby 

 urged as the best means for accomplishing this 

 purpose."
