Thoro have reeontly been returned to this offioo for .furthor
oonolderation and roport a large number of land oalos.
Attaohed thoroto f in about all cases, in a roport from tho
Director of the Geological Survey saying those lands aro situated
in a gonoral region known to contain valuable deposits of hydrocarbons,
and that* ho has reports indicating gas and oil in the
regions. In a few oases ho has suggested there was possible
jwator power where the lands border on the Duchesne river.
Under date of January 3, 1912, I reported, setting forth
the exigency now existing in the mattor of land sales, and roport-ing
that tho information offerred by tho Director added nothing
to what was known to every one here. Since then I have more
oarefully investigated those questions, honoo roport more filly.
The hydrooarbon doposits aro found In oar£h fissures from
a fow inohos to fivo or six feet in witrth. Those fissures run
in an almost direot line for oovoral miles, and all outoroppdnge
have boon known and located many years. Thooo fissuros run di-rootly
downward with few exceptions. Tho exceptions so far
found moan that a slight dip may exist noar tho surfaoo, when
lator it runs downward.
