From Prof. Lawton's report, men,
toned in these columns last week, the
following relating tn the trend of the
formations OF the Menominee range will
be found interesting reading: THE genei-
AL trend OF the formations of the iron
districts is east and west, but locally
there ia great modification. as in the re-
gion Of the Michignmme, Hemlock and
Paint river, etc, the trend is north and
south. or northwest and southeast. IL
is so also, east OF Crystal Falls, at the
Hollister mine and at the Dunn, Marto.
don, etc. At the Vulcan, Norway, Cha.
pin, Florence, etc, the trend Is east and
west. The general dip 81 the formation
is To the north but of course this Is locally
modified by the folding OF the formation
A matter that has not been clearly made
ont yet, is the fact that in the east end
oi the Menoninec range, To the west be-
yond Keel ridge, the dip is Co the south
and a very prominent bluff OF limestone
forms the footwall OF the ore. AT Iron
Mountain, however, at the Chaplin, Lud
ington, etc, mines, the dip of the lorna.
ton il to the north and the limestone IL
in the hanging wall OF the ore. There l.
no change in the rocks. The states and
limestone are identical, the dip is ne

that the formation at Iron Mountain IL

north and comes up with a. sOutherly
