strange geological phenomenon caused some
excitement recently at Murat village situated De-
tween the valley OF Mont Dore and that OF st. james.
In France. civil engineer had caused rectangu-
lar well to be sunk to q depth OF fftythree metres
through stratum Of hard tufa, which covers the
primitive formation in that district. At this depth,
which Is insignificant compared to the shaft OF
mine the heat nevertheless became 80 intense that
the worKmen had to be relieved at short inter-
walls. Their wooden shoes soon got intole-
rably warm, and they could not lie down to
rest themselves ON the hot ground. On the other
hand the appearance OF the tufa denoted that the
on leaving the spot for awhile, had recommended
his men TO be very careful during his absence, and
to content themselves with removing the rubble
without going further down. One OF them, how
ever in throwing the last shovelrul into the skip
took it into his head TO remove with his pickaxe
piece Of tufa, about thirty inch es IN circumference
but no sooner had lie done this than he saw the bot
tom OF the hole he had made swell up At the same
time loud rumblng noise was heard. The men, IN
to be pulled up. but they had barely got
to height Of q dozen metres when
thick column OF hot water preceded by violent
report rose up in the air projecting huge stones up
wards. The water In falling scalded the men griey-
Ously. The Jet diminished, and the well filled rap
idly, the poor fellows succeeding, however, in get
ting out In time. In the OF ten hours the well
got quite FULL and from that time rivulet OF ther-
nal water has been flowing from the spot into the
tains temperature OF forty degrees Centigr. Upon
analysis, 1t has been found to contain upwards OF
twenty milligms. NEARLY half gram, OF arseniate
OF potash per ltre proportion unheard OF before.
The Minister OF Public WORKS has sent commission
OF engineers to the spot for further investigation
