observed, thoiigli highly metamorphosed, on the sliores and 

 mountiiin-siiles. My own observations confirm this belief, and 

 I would add that these stratified or metamorphic rocks are not 

 horizontally imposed upon the granites, but their phine of pre- 

 sent position is inclined at an angle of perhaps forty-five degrees 

 with the horizon. On the eastern shore of the hike the mica 

 schists, shales, and crystalline limestone are to be found crop- 

 ping out — coming to a thin edge — at a point not over a mile 

 distant from the lake, and at an elevation of not more than two 

 hundred or three hundred feet, above which nothing but granite 

 occurs; while on the western shore these stratified beds are found 

 extending nearly to the summit of the range, at an elevation of 

 five thousand feet, and distant, on tiie incline, several thousand 

 feet from the water's edge. 



It is unnecessary to speak of the geology of the district any 

 further, or to repeat Pjofessor Dawson's careful observations 

 which are noted in his report ; but I will proceed at once to the 

 mineral resources, an examination of which was the object of 

 my visit to Kootenai. 



Mineral development is but just entering upon its earliest 

 stages in the district, and yet, for the short time since explora- 

 tion was commenced, a great deal has been done. On the west- 

 erly side of the lake is the Warm Springs Camp, so named from 

 a warm calcareous spring which flows out on the lakeside in 

 characteristic pools, basins, and terraces, the water of which 

 is said to be beneficial in some forms of skin diseases. 1 ascended 

 the mountain above the town of Warm Springs, to a height of five 

 thousand three hundred feet above sea level, by one trail, and de- 

 scended by another some miles to the southward, taking in en 

 route some of the principal prospects. There are apparently 

 five parallel ledges running north and south, some of them in a 

 crystalline limestone, others in the granite and altered schists, 

 and still others at the westerly contact between the limestone 

 and the granite. These lodes are located upon for two or three 

 miles north and the same distance south of Warm Springs, and 

 apparently vary from six hundred feet to one-half mile apart. 



There are more than three hundred locations filed in the dis- 

 trict. The ore is principally galena, with more or less native sil- 

 ver, some brittle silver, and a little sulphide of copper. Through 

 the courtesy of the officials I was permitted to make an extract 

 of the returns of ores shipped out during the summer of 1889 : 

 one hundred and forty-six tons assaying eighty-seven ounces of 

 silver; eighty-five tons, ninety ounces; seventy tons, two hundred 

 and thirty ounces; sixty-five tons, forty ounces; twenty ton?, one 

 hundred and twenty ounces; fifteen tons, two hundred and
