 C(EUR D'ALENE MOUNTAINS IN IDAHO DURING THE 

 SUMMER OF 1895.

ITINERARY. 



Iti compliance with instructions from the Botanist of the Depart- 

 ment of Agriculture, dated June .'5, 1895, to make a botanical survey of 

 the Canir d'Alene Mountains in northern Idaho with special reference 

 to the economic features of the flora, I left Hope, Idaho, on June 11. 



The field work was begun in the middle portion of the St. Mary basin, 

 thence carried to the upper part of this stream, and extended along the 

 divide between the St. Mary, St. Joseph, and the North Fork of the 

 Clearwater, taking in as much of the densely timbered portion of 

 the West and East forks of the St. Joseph as time permitted. 



After finishing here, the work was gradually extended northward, 

 and terminated with the exploration of the extreme western portion 

 of the North Fork of the Cceur d'Alene River basin, in the middle of 

 October. 



The time actually spent in the field was divided between the various 

 sections as follows: June 15 to July was devoted to the central por- 

 tion of the St. Mary basin and about the head waters of this stream. 

 July to July 14 was given to the summit of the high ridges which 

 separate the St. Joseph's tributaries from the North Fork of the Clear- 

 water and to the divides between the upper portions of the forks of 

 the St. Joseph. From the 14th to the 17th of this month the work was 

 in the lower part of the St. Joseph valley. From the 17th of July to 

 the 7th of August I was engaged in the valley of the South Fork of 

 the Cosur d'Alene River, with frequent side trips to the summits of the 

 divides which separate this stream from the St. Joseph and into the 

 valleys of the more eastern tributaries of the latter, which could not 

 well be reached from the upper St. Mary. From August 7 to August 

 13, I was employed in examining the eastern rim of the basin of the 

 North Fork of the Cu'ur d'Alene River. The time from August 17 to 

 September 1 was spent in the valley of the Clark Fork of the Columbia, 

 from the first easterly crossing of this stream of the Northern Pacific
