Quirk's paper of yesterday was to the effect
that much of the north shore Lake Huron grinds
and precises are metamorphosed sediments.
Read this paper when printed. Larson spoke
well of the paper, and Keith saw his rocks
and slides. He told me that Quirk is correct.
Miss Jonas' paper on Pre-Cambrian was
a very similar sequence to that of Franklin
Furace, some Paleogic relations to Pre-
Cambian with areas.
Guest on the Tampico Area paper. Has here
about 3000 feet of shales and marls almost devoid
of large forams. The upper 1000' has an abun-
dance of pelagic forams, while the lower 2000
has benthic forms. The upper series is of the
Cret (about Cretinichale) and is called the
Reloso. It has 700 forms of forams. The
lower series in the well known Papagayos
formation. Hand cores are put down to 50 feet
and or the forams are collected.
