southward to the next E-W road, in this series of
expressions for 58 miles there are many large lumps
of white shellstone marble and the regulative
small pieces of the Minisguri li. These crystals

large small pieces of limestone, and then the
regulative granitic like crystal bound together by
sandy dolomite. In this line of crystals there
are several large lumps of marble up to 60 or
more feet long. Seeing so many I now feel
we must have to call these lenticles formed-
Flacc. In one place then in a thick series
(about 30 ft) of a coarse grained white quartzite,

seen in the foots of the sandy dol of the crystal.
In places beneath these crystals is a
black soft shale, but farther north there is
greenish sandy slate. Age unknown.
Even if one say that the largest lumps are lentils,
still the crystals have large lumps dumped into the
mass along with the fall of Minisguri then redded
limestone. Most of these lumps look like shellturn,
