The hydro9raphis Branch to Be Illus trssed by Wall Diasram-Arizona Reclamation project to be Shown B. Working Model.


 The organization of the hydro graphic branch will be illustrated by wall diagram showing the divisions and sections into which it is divided for administrative and working Dur poses. The location of all field par ties of this branch working in 1904 will se shown ol a large wall map. the parties of the separate divisions being indicated by different colors. On this map will also be given the location of saging stations. A separate wall map will show he location of reclama- hon projects and the area of public lands withdrawn from sale or settle nent in furtherance of these plans. maps and diagrams of various dams. canals. and construction works, and she accompanying estimates prepared sy this branch will be exhibited.
 The fact that some of the states affected by the government irrigation projects are part of the territory in cluded in me Louisiana purchase makes the exhibit of the hydro graphic branch especially appropriate For this exposition.
 This branch will exhibit a working model, seven by twenty-one feet in area, of the SaN river (Arizona) recla- nation project. It will illustrate irri- sation as practiced in the vicinity of Mesa, Arizona This model will show she Salt river reservoir and adjacent mountainous country and the immense dam by which the water is impound- ed. On the model this reservoir will be about five feet in length and will se about five feet in length and will se filled by Tater represented as flow ng into it from Tonto creek and Salt siver and from springs bursting out rom the mountains. The canal by which electrical power is developed For the construction of the reservoir sam will be 'hown with water running in it from he head of the Salt river sranch of the reservoir to the site of She dam where fall of over 200 feet IS utilized to develop power The eowers and gates by which the water is let out If the reservoir into the stream bed below will be shown in operation The canyon of Salt river with the diversion dams and canals by

 Errigable land about the village SMesa, where the distributary canals N ,nduct the water to the lands irri- yated. The construction works used Eo control, regulate, and measure the How of water, such as headgates, fumes, division gates, measuring weirs, etc. will be shown in operation. The method of utilizing the fall of water in one of the main canals near the village of Mesa to develop electric power, the lighting of the village of Mesa by electricity, and the use of this power to pump water from the gravel beds 250 feet below the surface oI ahe desert will be illustrated. The orchards, vineyards, orange groves. and cultivated crops grown upon farms and village lots and the differ ant irrigation practices will be shown. Fhe model will be painted in colors stimulating Eature, and the conditions existing on ;be ground in 1903 will be reproduced.
 A large scale moCel of the Salt Eiver reservoir dam and one Of the &unnison river projects in Colorado, showing the diversion of water by means of a tunnel about 1-2 miles in length from Gunnison river to the 6ncompahg-e valley will also be exhibited by this branch.
