celery crop grown under the Skinner sj'Stem mature from 

 three to four weeks earlier and a proportionately larger 

 )'ield than the crops which were irrigated by sub-irrigation 

 methods, with the result that the)' brought a proportionately 

 higher price. 



The Skinner system consists of a series of lateral pipes 

 approximately Hfty feet apart extending over a held. In 

 these ]5ipes are inserted nozzles from three to four feet apart, 

 the nozzles being arranged in a row with absolute uni- 

 formity, this work being accomplished by means of a drilling 

 machine designed and patented b)' the Skinner Irrigation 

 Company. 



All special fittings required by this installation have been 

 developed and patented by the Skinner Irrigation Company, 

 and are devised in a manner to secure the best results and 

 most permanent life. Recently there has been developed a 

 device for rotating these lines from a point m tlie field, oper- 

 ating them not only together, but in unison. This saves a 

 large amount of labor and secures a uniformity of water 

 distribution not obtainable when each line is operated in- 

 dependently. 



One of the most recent developments brought out by the 

 Skinner Company is an automatic turning machine driving 

 the pumping engine, which rotates the pipes uniformly and 

 in unison, eliminating altogether the labor involved in irri- 

 gating. In some sections of the country, where the Skinner 

 system developed to meet special conditions, there has been 

 arlded an ecjuipment for spraying the entire acreage with 

 fungicides, insecticides and commercial fertilizers. A plot 

 of ten acres can be sprayed in five minutes' time, and the 

 work is done better than is possible by hand. A heating 

 device has also been added for raising the temperature of 

 the water in order to secure the fullest degree of frost pro-
