A Dulletll lICNE lIE OlllltL cNNIN' geological survey says that the survey will make an exhibit at the Louisiana Purchase exposition which will illus trate the surveys methods Of work and the products of it's various branches as completely as the space at its disposal will permit.
 The Salt River valley will be partic ularly favored and benefited by one prominent feature Of the exhibit. The bulletin referred to gives the fcIOwing particulars;
 The organization of the hydrograph- ic branch will be Illustrated by wall diagram showing the divisions and sec tions into which it ;s divided for ad- miaistra:ive and working purposes. The location of all field parties of this branch working in 1904 will be shown on a large wall map. the parties of the reparate divisions being indicated by 6ifferc7t colors. On this map will also pe given the location of gauging sta tions. A separate wall map will show the location of reclamat on projects and the area of public lands withdrawn from sale or settlement in furtherance Of these plans. Maps and diagrams of various dams, canals and construction works, and the accompanying estimates prepared by this branch will be exhib- ited
 The fact ttat some of the states af- fected by the government irrigation projects are part Of the territory in clude1 in the Louisiana purchase makes the exhibit of the hydrograuhic branch especially appropriate fer this exposition.
 This branch will exhibit Q working model, seven by twenty-one feet in area, of the Salt River reclamation project. It vii also illustrate irrigation os practiced in the vicinity of Mesa This model will show the Salt river res ervoir and adjacent mountainous coun- try and the immense dam by which tha water is impounded. On the model this reservoir will be about five feet ia length and will be filled by water rep resented as flowing into it from Tonto creek and Salt river and from e-7r,ngs bursting out of the mountains. re canal. by which electrical power is de- veioped for the construction of the res ervoir dam will ba shown with wate- running in it from the head of the Srlt river branch of the reservoir to the site of the dam, where d fall of over 200 feet is utilized to develop power. The towers and gates by which the water is let out of the reservoir into the stream bed below will be shown in op- cration. The canyon of Salt river. with the diversion dams and canals by which the fall of the river is utilized to develop further electric power, wi be shown in the model. Below the mouth of the canyon Verde river is rep resented as flowing into Salt river. and below the confluence of the rivers are the dams diver;ing the water into the canals by which it is conveyed to the irrigable lands ahout the village of Mesa, where the distributary canals conduct the water to the lands irrigat- ed. The construction works used to con trol, regulate and measure the flow of wSter, such as headgatcs, fumes di- vision gates, measuring weirs, etc. will be shown in ooTation. The method of utilizing the fall of wcter in one of the main canals near Mesa to develop cleo tric power the lighting of the village of Mesa by electricity, and the use of this power tc pump water from the gravel be9s 250 feet below the surface of the desert, will be Illustrated. The orchards. vineyards, orange groves and cultiva.- ed crops grown upon farms and village lots and the different irrigation prac- tices will be shown. The model will be painted in colors stimulating nature, and the conditions existing on the ground in 1908 will be reproduced.
 A large scale model of the Salt river reservoir dam and one of the Gunnison river project in Colorado, showing the diversion of water by means of tunnel six and one-half miles in length from the Gunnison river to the Uncompah- gre valley will also he exhibited by this branch.
