 There are also some late basalts which
 have no connection with the yninerali- Zation.
 | The Rush Is On.
 The rush to this new bonanza strike
 has been amazing and the most sur prising part of it all is how the peo- pie from such distant points got
 there so quickly. There are lots of
 people there from Colorado and Ne
 vada already and Los Angeles seems
 to have walked up as if the people meant to turn out en masse. The 1 building of this new railroad that con-
 meets Phoenix with Los Angeles will
 bring that city within eight hours of l Bouse. the center of the great Parker country.
 A lot of things are going to happen
 out there and happen very soon. | think this new bonanza strike is only | the first number in a brilliant series, { for as I said. there has been a good deal of prospecting going on there { by intelligent prospectors from Colo rado, Nevada and Utah for the last | six months. Many of these have ' been sent into the country by mining
 men able to follow up their efforts
 with ample capital to develop. The trains into the country now are run ming loaded Several towns of com ing importance have sprung up and are building up rapidly. These are Salome, the nearest point to the new strike: Bouse, the center of the great
 est activity. and Parker, on the river. which is destined to become an i'm
 portant smelting point and mining center.
 The Quartzsite country, twenty five
 miles south of Bouse, is especially rich in gold. The Dome Rock range.
 west of the camp. was the earliest scene of gold mining in Arizona and produced by dry washing seven mil lions and a half. Lode mining was almost impossible in those days, owing to the inaccessibility of the country and the cost of getting in machinery The deposits are very extensive but generally the grade is low. Nothing is ventured in the prediction that that country is going to produce number of good gold bonanzas in the near future. It needs development and milling facilities. It has great abundance of water in the Tyson val ley WHICH lltS NlOSt ltlt and is raised by windmills to irri- gate the gardens and furnish the mines with water.
 The Glory Hole.
 It is the astounding values in the new bonanza strike that has attracted the attention of the world. Richer rock has never come out of Goldfield or Cripple Creek. You have to speak of it in percentages as you do of cop per. it is so heavy-twenty. thirty and fifty per cent gold. Specimens Of this can be seen in the windows next door to the postoffice in Phoenix I saw rock coming out of the Glory hole l last Friday. just as good as that in the exhibit in the window. and I know that the deposit extends for a distance of 5 feet. I've seer just as good gold from the extreme end of 1t | as they have taken out of the Glory | Hole. But those poor fellows that 1 it don't want to open it 1 while the crowds are around. so much ! of the gold is carried off by people who want specimens to exhibit. Many wouldn't steal anything else in the world but would steal a s20 specimen without compunction. Those fellows | have actually had to dig a hole in | their camp to put the Jumps of gold | into and cover the hole up with a | mattress to retain any of their ore. l They are simple hearted fellows and | their friends who are ashamed to steal it coax it away from them.
 Geology of the Bonanza.
 The region immediately surrounding | this strike lies in the geologic horizon | of the Algonquin schists which here | in Arizona We call the Pinal schists | and the Yavapai schists. They over | lie the primary granite and have a | thickness where developed by mines in | Colorado of from 1000 to 1000 feet, | but in the Grand Canyon of the Colo | rado they show a thickness of over | 12,000 feet. according to the United | States geological survey. The erup | tive rocks in the vicinity of this strike | range from the very early basic dia- | bases to semi basic gray andesites. I | think they have probably not been | the influential factor in the mineral | ization. Great lenses of quartz have ! been developed in the schist, not from | the depths but by a process of segre- | gation when the schists themselves were in a semi-plastic condition at | the time of the up-lift, and the gold | appears to me to have a genetic con- nection with these quartz lenses, | somewhat as the gold in the Silver Peak district of Nevada has. The segregation process has beer studied | out there by the United States geo logical survey and throws much light | upon gold deposits by the process of segregation.
 These lenses in this ground appear | at the surface. but that 1 is only because the quartz has been harder than the surrounding schists which have been eroded. The lenses will probably be found just the same to a great depth. These that are now exposed on the surface were not orig-1 inally deposited on the surface, but have been exposed by erosion You can go to within half a mile of thef bonanza ground by a wagon and you can ride all over by wagon and you you can ride all over Bonanza hill and Gold Bug hill on horseback by picking your way. The ground is not bare, but is covered with detritus and soil and is pretty well grassed. I saw three springs of water in Bonanza Gulch within a quarter of mile of the strike and several wells have been
