AURIFERoUs GRAVEL
 OF TEE COLORADO RIVER.

Whence many bursting stream auriferous fows."
 For hundreds of miles along the course
 of the mighty Colorado oi the West are
 mammoth deposits of gold bearing gravel.
 h the Grand, Boulder, Iceberg and Black
 canyons, where the impac, wa, greatest
 when the waters that at one time covered
 the state of Utah broke through chain
 after chain oi mountains on it's tortuous
 way to the gulf, is the great beds of
 gravel most noticeable. In places the
 gravel and sedImentary deposit is fully one hundred feet in depth and extends
 lar back into the canyons debouching into the river. Under these deposits is a soft cement bedrock usually rich iu coarse gold. From the moath of the Grand Canyon, at Pierce Ferry, to Old Callvilie, in the Big Bend, nearly all the available banks Of gravel and accessible river bars have been located. Tselve
 miles above Bonelh's Ferry at what Is
 known as Temple Bs-, the Temple Bar Consolidated Mining Company have un- der location several thousand acres of immensely rich placer ground. The gravel lies back from the river on g high bench sloping downward toward the stream. In places the deposit Is fifty or sixty feet in depth and carrying gold from top to bottom. On bedrock coarse gold and nuggets have been found, one nugget weighing oyer three ouuces. A few years ago an attempt was made to work the ground by means of a current wheel in ths river hut the m machinery was crude and the attempt proved failure A reorganization of the company took place and H. J. Dslamer, the president, took personal charge. Under his able management order has been brought ont of chaos. Hydraulic engineers of world wide reputation have examined and re. ported feasible plans to work the grounds and already the preliminary work is al most completed. Piers have been placed in the river near the mines and to these piers chain of booms are being at. tached to glance fl ,od wood into pocket in an eddy in bend in the river below. It IS calculated that fully 100 900 cords of wood can be empounded in ihls pocket, and pulled high and dry with steam weDeh or allowed to remain in the boon, until the receding water leaves 1t on the bank. Boilers of three hundred horse power capacity are being hanIed to the mines and by the first of May they will be ready to operate the big hydraulic pumps against the great masses of gravel Machinery and supplies are being rushed to the mines that everything may be in readiness to take advantage oi the first rise in the river when flood wood. it is thought, sufficient to run the plant for year will be caught. Mir. Delamer has conducted the affairs of the company with rare good judgment and to him the company will owe their full measure of sucress, should success crown his efforts
 Upon the success of this plant will de- pend the installation of many similar hydraulic plants on the river. At least 30 900 acres of placer ground Is now un. der location, and ss 1t is all wonderfully rich way will he found to work it. A sample of its richness was given by the Temple Bar Company last year when a twelve inch stratum of the gravel on bedrock returned 3O$ to the cubic yard In dry washer. Within five years ny. draulic plants will line the Colorado river from the Grand Canyon to the Needles cad Mohave county will become the greatest gold producing country in the west
