but depends as well upon the lift to be 

 overcome. By multiplying the brake 

 horsepower per foot of lift by tlie lift, 

 from data given in the next table, an 

 idea is obtained of the size of engine 

 needed. 



Number of 



Centrifugal Brake H. P. EfTiciency 



Pump per foot of Pump 



2 ; 08 30% 



3 14 40% 



4 22 45% 



5 34 50% 



6 46 50% 



Hence, in the example given above, if 

 the suction lift from the surface of the 

 water, when down to pumping level, is 

 eighteen feet and the rise from pump 

 to discharge is ten feet, then the total 

 lift is twenty-eight feet, requiring, for 

 the six-inch pump, .46 h.p. for each foot, 

 or an engine of 12 h.p. (11.28 to be 

 exact). Some idea of costs in normal 

 times is presented in the following 

 table: 



COST OF CENTRIFUGAL PUMP 



No. 2 $ 40.00 



No. 3 60.00 



No. 4 75.00 



No. 5 85.00 



No. 6 115.00 



COST OF ENGINES 



Electric Gasoline 



Horsepower Motor Engine 



5 $110.00 $375.00 



10 200.00 550.00 



20 320.00 850.00 



40 450.00 1600.00 



A comparison of fuel, based on per 

 brake horsepower per hour, permits an 

 inquiry into which is cheaper, low in- 

 stallation and high fuel cost, or the 

 reverse: 



If gasoline is S0.06 $0.10 ?0.20 $0.26 



Other fuels are worth : 

 Crude oil, per bbl.. .55 .93 1.85 2.42 



Coal, per ton 2.00 3.33 6.66 8.66 



Electric power, 



per k.w. hour Ill .185 .370 .480 



Cost per brake h.p. 



per hour 100 .166 .333 .433 



For a rough estimate to cover cost of 

 valves, priming pumps, all fittings, and 

 suction but not discharge pipe, add 10% 

 of the cost of pump and gasoline engine, 

 or 20% for an electric plant. Installa- 

 tion costs about 5% of the equipment 

 cost. Protection, in the way of a house, 

 costs somewhere in the neighborhood 

 of $40 or .$50 for an ordinary sized 

 plant as usually constructed. On esti- 

 mates of costs, freight and hauling must 

 also be included. Fixed charges are 



usually figured thus: 



Gasoline Electric 



Plant Plant 



Depreciation and renewal.... 8% 5% 



Repairs and maintenance 3% 1% 



Interest at annual rate of 6% 6% 



Attendance amounts of about 5 cents 

 per hour of actual running for an elec- 

 tric plant and 10 cents for gasoline 

 plants. 



Conveyance of Water. The most 

 common method of conveyance is the 

 open earth ditch. As water increases 

 in value, the usual open ditches are 

 subjected to concrete lining or else re- 

 placed with cement or wooden or steel 

 pipes. Lewiston Basin, in Idaho, is sup- 

 plied with water brought over rolling 

 hills in redwood stave pipes; the lemon 

 groves of Corona, California, obtain 

 water through concrete lined canals; 

 the water obtained by citrus growers 

 from the Riverside Water Company is 

 conveyed in cement and vitrified pipe,

The horse is a vital factor in 

 greater farm production. To realize 

 the best results he must be kept one

STUFFED COLLAR PADS 



Filled with our Special Composite Stuffinc

 better than other kinds, being soft, 



Bpringy and absorbent. They also make possible

NEW PATENTED HOOK ATTACHMENT 



(Found Only on Pads Made by Us) 



Consists of wire staple with felt washer. 

 It gives hook a firmer hold and prevents pull- 

 ing off, even though fabric Is weakened by 

 long usage. Life of pad is thus materially 

 lengthened. This is the greatest improve- 

 ment since we invented the hook. Ask your 

 dealer for Tapatco Booklet.

 twenty-four inches bottom width, six 

 inches deep and sloping sides, with a

 will carry about one and one-half cubic 

 feet per second. 



Preparing for Irrigation. Careful 

 determination of the direction and rate 

 of slope previous to planting an orchard 

 will help to determine the direction of 

 the tree rows, but whether irrigation 

 plans precede or follow planting, a sur-

 contour of the land prior to actually 

 installing the system. In general, when
