IRRIGATION BY PUMPING 125 , thus irrigating large tracts of lands. Although the largedistillate engine which requires the services of an engineer is not aseconomical as a high-grade steam plant using the cruder unrefinedoils, yet as the irrigation of much of the country is subject to inter-ruption, the lower first cost of the plant and the short time it is usedoffsets the higher fuel cost. Many of the owners of orchards in southern California are supply-ing themselves and neighbors with water by engines which are notvisited sometimes more than twice in a days run of ten hours. Theengines are reliable and fairly economical, if ordinary attention isgiven them. A still higher economy may be obtained when thereare introduced various forms of producer gas from either oil or coal. Water Power.—The ust of water power is, theoretically at least,the most economical of met
