problems that properly belong to the
bureau of mines and which should
eventually be undertaken, such as
methods of mining and metallurgioal
processes, but these activities will be
deferred for the most part until con-
gress both on the bureau of mines
Legislation and on the appropriation
items emphasized the desire to re-
gard the mine accidents investiga-
lions as urgent and this will be the
feature of the work.
In all, $4,000 was appropriated
for mine accident Investigations or
this sum under the general plans ap-
proved by the the secretary of the in
terror, 100000 is to be spent OH the
rescue station, $4,000 for housing
nine stations; $4,000 for equipping
eight new stations, and $4,000 for
additional equipment of five existing
stations. The allotment for the in
vestigation of explosives is $40, 900;
for electricity in mining, $4,000; ap-
planes for preventing mine aecid-
ents, $4,000; examination and codi-
fication of mining laws, $4,000; and
other technologic Investigations. ore
treatment etc, $4,000. For The
Analysing and testing of the Goals,
lignites, ores, and other mineral fuel
substances belonging to Or for the
use of the United States, S100 900
was appropriated. OF this amount,
$4,000 will be spent in the chemical
and physical investigation of fuels;
SIS 900 in the inspection of govern
ment fuel purchase; $4,000 in fuel
efficiency Investigations; $4,000 in
Ignite and peat Investigations: and
$4,000 in briduetting Investigations.
The mine accident Investigations,
which have been transferred from the
geological survey to the bureau nj
mines were first authorized in the
Legislative appropriation act of May
%, 1908, carrying for this purpose
an appropriation of S150,000. This
was followed by a similar %appropria-
ton carried in the act for the sundry
civil expenses of the government for
1910. A mine experiment station
was established in Pittsburg during
1908, at which, since that time. in
vestigations of explosives, coal gas,
dust, electricity and other possible
causes of mine explosions have been
continually under way. The mining
engineering field force of the geologi
cal survey has already made decided
progress in the study of underground
mining conditions and methods.
Practically all of the coal mines in
which mine explosions have occurred
during the last two years have been
carefully examined. the gases. coke
and dust have been analysed at the
laboratory at Pittsburg and every eff
fort has been made to determine the
explosibility of various mixtures of
gas and air in the presence of differ
ent types of explosives. Considerable
progress has also been made in the
investigation of explosives used in
coal mining, and the conditions under
which they may be classified among
the permissible explosives. TIE in
vestigations and educational work in
connection with the use of ARTIFICIAL
breathing and other types of mine
rescue equipment the so-called oxy-
gen helmets, have not only been USE
full in developing a more satisfactory
use of such equipment in the examin-
alton of mine explosions, but also
better methods for using this eq l p
ment in mine rescue work.
