A4 INJURY BY SMELTER WASTES. 
Very few marks of this fire were seen on the eastern slope. On a very 
small area at the southern end of the western slope a fire occurred 
about eighteen years before the date of inspection, and part of the 
northern slope was attacked by a fire approximately forty years ago. ~ 
Many of the trees on the northern slope had absolutely no fire scars 
and yet were dying in the same way as those on other parts of 
the mountain. At several points there were very small areas where 
camp fires had been built recently, but in no case were more than 
five or six trees attacked by such fires. Wherever lodgepole pines 
occurred on this mountain they were in excellent condition, but the 
red and balsam firs were practically all dead or dying. The same 
course of reasoning as that adopted in the previous case proves that 
these red firs. were injured and killed not by fire, but by some cause 
that was still active during the summer of 1908. 
A trip was made up Storm Lake Canyon to within about a mile of 
Storm Lake, the farthest pomt reached being about 17 miles from 
the smelter. On the eastern side of the creek the slope was mainly 
covered with lodgepole pines and a few red firs, and no damage was 
noted except to the latter. On the western slope of the creek there 
were many red firs, and those were badly injured, some being dead and 
some dying. There were no signs of recent forest fires to account for 
this injury. The west slope was examined for only about 2 miles up 
the canyon, but throughout this area the injury to red fir continued. 
In the bottom of the canyon the trees at the entrance were mainly 
balsam firs and lodgepole pines; farther on white pines and spruce 
began to appear. No injury to any of these trees was noted, except 
that for 4 or 5 miles up the canyon the balsam firs were badly killed 
and injured; beyond this distance they appeared to be healthy. 
There were no fire signs to account for the death and injury of these 
trees. 
Another trip was made from Anaconda up Warm Springs Creek to 
Silver Lake and then to Georgetown Lake, the farthest point reached 
being about 18 or 19 miles from the smelter. Injury to junipers 
was not observed at any point. The lodgepole pines were killed in 
the vicinity of the smelter, but the injury gradually grew less and 
apparently ceased at a distance of about 10 miles west of it. The in- 
jury to this species of trees extended about the same distance from the 
smelter as it had done two years before, in 1906, while the red firs in 
1908 were injured for about 3 miles farther from the smelter than 
they were at the previous inspection. Extreme injury to this species 
of trees was noted all the way to Silver Lake, about 15 miles from the 
smelter, and considerable injury from Silver Lake to the vicinity of 
Georgetown Lake. The southern side of Silver Lake had been visited 
by fires about twenty-two and fifty years before 1908 that killed 
some trees, but red firs were gradually dying when the examination
