[NO. 71. ditches are now owned by the San Felipe Agricultural, Mechanical,and Irrigation Company, the shares in which are held by owners ofthe land commanded by the ditches. The total cost of the ditcheswas about $25,000, and the annual cost of maintaining them is about50 cents per acre per annum. The main ditches measure about 4^miles in length and are 10 feet wide at the top, have perpendicularsides, and carry about 2 feet of water. The laterals are four innumber, with an average width of 4 feet and a total length of 24-Jmiles, making the total length of the ditches 30 miles. The areairrigated is 3,600 acres (in meadow, cotton, corn, gardens, orchards,. Ftg. 6.—Map of Del Rio irrigation system. and vine37ards), although 5,000 acres can be irrigated. All kinds offruits and vegetables are grown in profusion. On June 15 of thisyear (1902) melons, plums, and apples were ripe. The impressionmade on the traveler who comes from the droughty and sun-scorchedplains is not soon forgotten. This cultivated tract has been so iso-lated from the rest of the agricultural world that none of the diseaseswhich so reduce the profits of the grape and fruit grower elsewherehave yet been introduced. Grapes produce from 6,000 to 10,000pounds to the acre, and are mostly made into wine, the yield of whichis from 10 to 16 barrels to the acre. U. S. GEOLOGICAL SURVEY WATER-SUPPLY PAPER NO. 71 PL. V
