are said to be very interesting. Among
other things which have been proved
there, is the fact that fast-grown TIM

During an Arctic exploration Lieu
tenant Ray investigated the depth to-
which the ground was frozen. He SAYS:
II dug an earth shaft thirty-eight feet
in depth, for the purpose of testing the,
temperature. and found, on calculation,l
that it is frozen to depth of 800 feet.
A bucketfnl of the st Iff taken out of
the shaft, when thawed out, separated
into earth and water. about four inches
of the latter standing on top. This
proved that if the ground there were
ever warmed sufficiently to be resolved
into its original parts it would be found.

thing on its surface. 1t is really frozen,
