62 TRANSACTIONS OF THE [ FEB. 9, 
observed, though highly metamorphosed, on the shores and 
mountain-sides, 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 plane of pre- 
sent position is inclined at an angle of perhaps forty-five degrees 
with the horizon. On the eastern shore of the lake 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; whileon 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 the 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 Professor 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 ont 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 oreis principally galena, with more or less native sil- 
ver, some brittle silver, and alittle 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 tons, one 
hundred and twenty ounces; fifteen tons, two hundred and
