No. 28. L. M. Parkhiirst, of Atlantic County, irrigates 3 acres from 

 a 3-inch bored well 50 feet deep. The well is provided with a 6-foot 

 strainer, and the water stratum is gravel. The water stands 23 feet 

 below the surface. The cost of the well was $50. A No. 8 hot-air 

 engine drives a pump dehvering 8.3 gallons per niinute. The total 

 lift of the water is approximately 26 feet. The fuel used by the 

 engine is kerosene, purchased at 9^ cents per gallon, and in twenty 

 hours' run the fuel consumption is 7 gallons. The plant cost $350 and 

 used 5 barrels of kerosene in 1905. Water is pumped into an earth 

 reservoir 22 feet square on top and 4 feet deep, lined w^ith 1-to-l 

 cement 1 inch thick. The construction of the reservoir required one 

 fv^reman, two field hands, and one team for four days, making a labor 

 cost of about $25. It is fairly tight, though the Uning is cracked in a 

 few places. 



The furrow system of irrigation is commonly used, though occa- 

 sionally land is watered by hose. The furrows are 400 feet long and 

 4 feet apart. The discharge from the reservoir is turned down one 

 furrow, through which it flows in about thirty minutes. It requires 

 five hours to irrigate one-half an acre, using one reservoir full, or a 

 depth of about 0.9 inch. 



The ground is a black waxy loam 7 inches deep, with a gravel sub- 

 soil. The ground is irrigated in dry weather once or twice a week. 

 Strawberries receive at most three irrigations. Two acres in straw- 

 berries yielded in 1905 4,000 quarts per acre, while unirrigated land 

 jaelded but 2,800 quarts per acre. Potatoes, which received one irri- 

 gation in 1905 rather late in the season, yielded one-fourth larger 

 crop than unirrigated potatoes. Irrigation will in general increase 

 the }ield from one-third to one-half. 



No. 29. Herman Graumann, of Atlantic County, irrigates 10 acres 

 planted to strawberries and truck, from three 2i-inch driven w^ells 22 

 feet deep, the water level in which is 16 feet below the ground. The 

 wells, wliich are located far apart, cost $15 each to drive and are 

 pumped by means of a portable 2 ^-horsepower gasoline engine, which 

 drives a double-acting power pump, delivering 33 gallons per minute. 

 The pump and engine, w^liich are mounted on the same truck, are 

 hauled from well to well, as required, and the water discharges through 

 a 3^-inch canvas hose from 50 to 1,000 feet in length, whence it is dis- 

 tributed over the land by sprajdng. The pump will irrigate one acre 

 in four hours. 



The soil is a sandy and waxy loam 12 inches deep with a gravelly 

 clay subsoil. Truck is irrigated every seven days; strawberries every 

 one or two days in the driest weather. Strawberries are watered by 

 furrows 80 feet long and 4 feet apart, and it takes the water twelve 

 minutes to flow through. Two men are required to operate the pump 

 and distribute the water. Irrigation in dry years increases the return
