SOME RAILROAD WATER SUPPLIES. 
BY L. H. PAMMEL AND ESTELLE D. FOGEL. 
Complaints are frequently made with reference to rail- 
road water supplies. These complaints come from pas- 
sengers as well as stockmen who are compelled to use the 
water for their stock. 
To study some of these problems investigations were 
made of a number of the railroad wells of this state as well 
as some along the Northern Pacific railroad in Dakota and 
Montana. The work is not completed blit the facts ob- 
tained may be of interest to the users of these public water 
supplies. 
It may be of interest to state that the water supply of 
one municipal corporation, which was also used by the 
several railroads entering the city, contained Colon Bacillus. 
It makes it extremely desirable that railways should be 
very careful of the water used for their passengers. The 
railroads have, no doubt, in some cases been responsible 
for the conveyance of typhoid fever. The railroad water 
supply should be examined chemically and bacteriologically 
from time to time. The chemical analyses appended were 
submitted by Dr. J. B. Weems and C. E. Ellis. 
Quite a number of different species have been found. In 
well waters from the west the following species have been 
determined. 
Planosarcina mohilis (Maurea) Migula, Micrococcus cinna- 
bareus Flugge, Micrococcus coralinus Centanni, Bacterium 
glaucum Maschek. Bacillus aurescens Ravenel, mealy 
orange.
