for the precious metals show that old ground can be gone over again by prospec- 

 tors, and what was considered worthless then, may now be of great value. It is 

 in just such parts of the country as this, that the men who put in a few hundred 

 dollars at the time when it is attracting the least attention, eventually reap the 

 greatest returns for their investment. Rosita has these advantages : a situation, 

 in what has been proven to be a rich mineral belt ; proximity to supplies and 

 transportation; winters so mild, that generally, out-door work can be done 

 at all seasons; old enough to have a civilization and settled population. What is 

 wanted now, is the attention of and investigation by capitalists, or experts repre- 

 senting them. 



There are several miners here working and shipping ore. By the time for 

 another issue I will endeavor to ha re some facts regarding them, that I trust will 

 be of interest.

SPRING IN THE ROCKY MOUNTAINS. 



Golden, Colorado, April 8, 1879. 

 Editor Kansas City Review of Science : 



April 3d to 5th I spent in the main central range of the Rocky Mountains 

 west of Gray's Peak, about in latitude 39 , 38' north, longitude 105 , 53' west. 

 My altitude (all deduced from spirit level heights) was from 10,130 feet to 11,900 

 feet above the sea. The main valley runs in an east and west course ; the side 

 valley, which leads to an abrupt, sharp divide between the waters of the Atlantic 

 and the Pacific, which is the main crest of ihe great Rocky Mountain range, 

 called Loveland Pass, is selected as the best location for crossing the Rocky 

 Mountains with a railway line to the promised land of rich carbonates, called 

 Leadville, Carbonateville, and Ten-Mile Valley. 



We have had a permanent camp in the main valley since March 25th, just 

 where a fine little glade or open park, fringed with pines and spruce, spreads 

 itself at the northwest foot of a mountain, called the "little Professor," some 

 13.000 feet altitude 



Contrary to all we expected, we find a surprising and agreeable temperature 

 all day long. Scarcely a breeze moves the graceful foliage of the spruces and 

 Canada balsams. The snow lies on the north slopes from three feet to eight feet 

 in depth ; on the south slopes and the edge of the park, we find abundant bare 

 ground, while on every side the melted sn >w trickles under the crust in thou- 

 sands of rills, and s veils daily the small brook that occupies the centre of the 

 valley. When Horace sang : 



" Solvitur acris hiems, 

 Grata vice veris et Favonii, " 



he could not have described more closely the effect that a southwest wind causes
