YUMA, Ariz. - A three days carnival to celebrate the completion of the great irrigation siphon under the Colorado River began today. Addresses were made by Governor Hunt of Arizona and Lieutenant Governor Wallace of California.

The completion of the siphon marks a new era in the history of historical Yuma. Nearly 150,000 rich acres in a climate where things grow twelve months of the year are now supplied with an abundance of water and are rapidly being planted to fall and winter crops.

Activity is the word on every hand. The business men of Yuma are increasing their stocks to meet the demands the steady influx of new settlers is creating. A new $50,000 high school is going up, a Carnegie library is underway, and the new theater is one of the largest in the Southwest. Building permits run into six figures, and Yuma is started on the road to prosperity.

The Yuma siphon is a concrete tunnel fourteen feet in diameter and nearly one thousand feet in length. It is forty feet below the bed of the turbulent Colorado River, and over one year was required for its construction. The irrigation water direct from the Laguna Dam reaches the siphon by means of a mammoth canal, falls down the shaft of the intake on the Colorado and, rushing through the tunnel, bubbles up through the shaft of the outlet on the Arizona bank and on to its work of reclamation in the valley below.

What this unlimited supply of water will mean to Yuma Valley is not a supposition, nor is it an experiment. That part of the valley which has been cultivated has demonstrated beyond doubt the agricultural, horticultural and viticultural realities of Yuma Valley.
