_New Water Supply_.--The writer was directed to find, if possible, a
supply of good water, and his efforts proved successful. The pure water
now in use has eliminated the adverse conditions before mentioned; has
improved the _esprit de corps_ of the train service; and, in a short
time, the reduction in operating expenses will liquidate the first cost
of the new supply.

This supply is taken from the South Fork of Bonito Creek, which flows
down the eastern slope of White Mountain. The latter is 12,000 ft. high,
and is 16 miles south of Carrizozo (Fig. 1). The watershed is a granite
and porphyry formation, heavily timbered, and the stream is fed by snow
and rain. This combination yields an excellent water, carrying on an
average 6.05 grains of incrusting and O.95 grains of non-incrusting
solids per gallon. The North Fork of the creek carries 16.60 and 2.40
grains, respectively. Below the junction of these forks, the water
contains 10.48 grains of incrusting and 1.57 grains of non-incrusting
solids per gallon; and a branch pipe line takes water from the creek
during intervals in dry years when the daily flow of the South Fork is
less than the consumption.

_The Water Plant_.--The water is taken to and along the railway in pipe
lines. The system includes 116 miles of wood pipe, 19 miles of iron
pipe, one 422,000,000-gal. storage reservoir, four 2,500,000-gal.
service reservoirs, two pumping plants in duplicate, and accessories of
valves, stand-pipes, etc.

From a small concrete dam across the creek at an elevation of 7,728 ft.,
the pipe line drops down the narrow valley eastward, 5-1/2 miles, to an
elevation of 6,980 ft, where it turns abruptly north, rising in 1 mile
to a tab
