Tuesday, Sep. 11-1923. Waterville. Left Augusta at 7.30 A.M. and left m matt along outside of Kennebec river to Waterville where we arrived at 8.30. Distance 20 miles. Highly metamorphosed strata occur north of Augusta for 5 miles and more, and comes in a slate-like then series of dark beds, probably the Waterville Silurian. Got into connection with Prof. Edmond St. P. Heins by mine of school, and I explained what I wanted to learn. He then told me of his summers, with a Mr. Smith, a young man who wants to go to Harvard, but only teach this next year at Union College at Schenectady. The Penobscot formation is well developed all about Belfast and occupies nearly all of the northwester corner of the Belfast Sheet. It's thmpfr Type of Cambrian age. What I saw of it later in the day is a dark fine-grained sandstone considerably metamorphosed. At Belfast it is shot thmp with igneous material, and about 5 to 8 miles to the northwest occur intrusion of granite and diorite and dikes of Camptonite. They stand nearly an end, but 2 miles N.N. of Belfast dip about 40° to the southeast.
