wide, and its direction north 55° east. In all other points it resembles 

 the other lodes. * 



Rover State. — Discovered July 24, 1873. Its width is abont 2 feet and 

 strike north 05° west. Connecting this lode with the Pacific, there is a 

 smaller one, G inches wide, called the Sidney. 



Pacific. — This lode was discovered in July, 1872. The strike is east 

 of south. It has seams of diiierent widths. The ore has assayed by 

 blow-pipe about $10 i)er ton. 



Helena. This lode was located in July, 1872, and is from 6 to 8 inches 

 in width , striking north-northeast and southwest. 



Cape Horn. — This lode is from 10 to 15 feet in width, and has been 

 tracedm ore than 1,000 feet. It strikes north 65° west, and dips east of 

 north at an angle of about 7o<^. .The ore is said to assay 150 ounces per 

 ton. Connecting the Cape Horn with the Anna is the Erie, about 6 

 inches in width. 



Anna and Washington. — The Washington lode is a continuation of the 

 Anna, the extent of both being 3,000 feet. The discovery was made 

 July 25, 1873. The strike is north 55° west, and the dip southwest. It 

 is in a very black shale, and between it and the Cape Horn there is a 

 bed of quartzite. The width is about 5 feet, which increases in places. 

 The ore is of the same character as in the other lodes. Mr. Kirker, one 

 of the company owning the claims, assures me that as far as he has 

 traced the lodes, they seem to converge toward the Anna and Washing- 

 ton. He says also that west of these there is another set, of which the 

 following are the principal ones: Montreal, 15 feet in width 5 Bear 

 Hole ; New Chicago, 3 feet wide ; Deep Hole, 1 foot 6 inches ; St. Louis; 

 Wisconsin; Superior; Tempest; Lily; Hoosier; Lookout; Cashier and 

 Silver Wing. These, he says, seem to conv^erge toward the Montreal, as 

 those in the other group do toward the Anna and Washington. All the 

 lodes are owned by the Eough and Eeady Company, composed of the 

 following members: E. A. Kirker, William Gant, Samuel McMillen, 

 Benjamin Graham, Louis Brant, James Brennand, and C. M. Defabauch.

KEPORT UPON OffiEE GEOLOGY OP THE SAN LUIS DISTRICT. 



Section a — The district assigned to the San Luis division for topo- 

 graphical and geological survey for the summer of 1873 is bordered on 

 the north by a line running east to west six miles south of Pike's Peak, 

 on the west by the one hundred and seventh meridian, on the south by 

 a line running east to west twelve miles south of Saguache, and on the 

 east by the eastern slope of the Front range. 



It can be appropriately divided into three sections, as shown by the 

 accompanying diagram. Section a, comprising the northeast portion of 

 it, separated on the west, southwest, and south from the others by the 

 Arkansas Eiver. Section h contains the southeast portion of the dis- 

 trict, terminating westward with the western border of San Luis Valley, 

 and from tbere northward with the well-known Poncho Pass. On the 

 north it is bounded by the Arkansas. Section c represents the 

 remainder, the western i)art of the district. 



Along the eastern portion of section a we notice the heavy masses of 

 mountains, cut by deep canons and gorges, showing that characteristic
