IRRIGATION IN SPAIN.

IRRIGATION IN SPAIN.

The successful termination of the monster syphon made to carry the water of the Aragon and Catalonia irrigation canal across the valleys of Sosa and Ribadono, will make fertile a vast tract of land in Spain. The system of construction employed was concrete on frames, and no little curiosity was evinced by engineers in the result of what many considered to be a hazardous experiment. It has turned out a complete success. Some 2,000 men were engaged on the work from July to October of last year. The most remarkable feature of the work is the syphon referred to. It is composed of two main tubes, five-eighths of a mile in length and twelve feet five inches in diameter, with a capacity of about 7./O0 gallons of water per second. The tubes have a lining of steel plates three millimetres in thickness, being bound round bv iron hoops, the whole being covered with concrete, which preserves the metal from the action of the water and the air, and enables any ecessary repairs to the tubes to be effected at little cost. The canal will bring water to more than 247,000 acres of land that is actually barren through lack of water.
