260 Charles Whittlesey.— A. Winchell 
lished by colonel Whittlesey, in the National Magazine of 
New York, entitled, "Two Months in the Copper Regions." 
From 1847 to 1851 inclusive, he was employed by the United 
States in the survey of the country around lake Superior and 
the upper Mississippi, with reference to mines and minerals.^ 
Subsequently he spent much time in the mineral district of 
the lake Superior basin. The wild life of the woods, thread- 
ing the stream with voyageurs and sometimes without a guide, 
was full of attraction for him. He was not, however, a rude 
hunter, nor a random explorer. He studied the forest as he 
advanced ; he noted the topography, he measured the rock- 
masses and preserved in diagrams the knowledge of their 
attitudes and superpositions ; devoting in all, fifteen seasons 
to the trying experiences of exploration in a country present- 
ing all the hindrances and hardships of one of the most diflfi- 
cult and trying districts of any part of the earth. 
In 1849, 1850 and 1858, he explored the valley of the 
Menominee river from its mouth to the Brule. He was the 
first geologist to explore this "South Range." ^ He examined 
the north shore of lake Superior from the present site of 
Duluth eastward one hundred miles ; and his examinations 
extended westward along the St. Louis river, to the neighbor- 
hood of the national boundary. His observations in Minne- 
sota were published by the State in ISee."* 
In 1858 and 1859, he was employed by authority in the 
prosecution of geological surveys in Wisconsin. He had 
been the first to make scientific observations worthy 
of recognition in northern Wisconsin, while connected 
with Dr. D. D. Owen's national survey, in 1848. In 
1860, he was again invited by state authority to con- 
tinue work in the same region, and made to professor 
James Hall a report on Ashland, Bayfield and Douglass coun- 
ties which has never been published — the survey having been 
interrupted by the war.
