INVESTIGATION AT ANACONDA, MONT. 21 
were badly spotted and injured for several miles from the smelter, 
and down as far as Race Track the crops did not appear to grow as 
luxuriantly as those around Deer Lodge. The trees growing in the 
valley were so few in number that it was nearly impossible to judge 
what their injury might have been. In several places examined south 
of Race Track the soil that had been irrigated by Deer Lodge River 
water appeared to be injured, especially near the irrigation ditches. 
This injury was shown by bare spots in various fields, such spots often 
showing a blue-tinted crust that evidently contained copper. This 
was especially true in fields along the river in the vicinity of Race 
Track. Beyond this point no serious injury to the few trees remain- 
ing was noted. The crops of alfalfa, potatoes, clover, etc., examined 
beyond Race Track did not show any evidence of having been at- 
tacked by smelter fumes. 
A trip was next made from Anaconda along the western side of 
Deer Lodge Valley until Lost Creek was reached, the valley of this 
creek being followed for about 7 miles. Samples of cattle-food 
materials, soils, and foliage were collected and observations were 
made on the general appearance of the vegetation. In Lost Creek Val- 
jey the junipers were absolutely uninjured, and the lodgepole pines 
were badly injured at the lower end of the valley, but the damage 
gradually grew less until it became practically insignificant at a dis- 
tance of about 5 miles up the valley. Throughout the entire 7 miles 
f the valley the red firs were almost all killed, although an occa- 
sional live one, or a group of them, would be found. 
A trip was made from Anaconda along the western side of Deer 
Lodge Valley until Modesty Creek was reached. The valley of this 
creek was followed for about 5 miles. Samples of cattle-food ma- 
terials, soils, and foliage were collected and observations were made 
en the general appearance of the vegetation. The lodgepole pines 
throughout this valley were injured to only a very slight degree, this 
dis:ance evidently being near the extreme limit of injury for this 
species of tree. About 50 per cent of the red firs were dead or badly 
injured and those remaining did not appear to be healthy. 
Another excursion was made from Deer Lodge up the valley of 
Tin Cup Joe Creek for 2 or 3 miles. The lodgepole pines were un- 
injured and reforesting was taking place. The red firs were hardly 
touched, only the older ones showing any injury at all, while young 
red firs were rapidly springing up. On the whole it appears that 
this valley is beyond the limit of injury to lodgepole pines and at 
the extreme limit of injury to red firs. 
EAST OF THE SMELTER. 
The only trip made to the east of the smelter was in connection 
with the return trip from Deer Lodge, already described. As far as 
the wriier examined east (which was to J. R. Perdee’s place, a dis-
