Excursion to Mt. Monadnock.
This excursion, primarily for students of glacial geology, is intended also to afford an opportunity to study the type example of a remnant mountain of harder rock left standing above the New England plateau, when the latter was worn down nearly to base-level during a former cycle of erosion. The party will leave this evening, returning tomorrow night. It will be conducted by Mr. J. B. Woodworth.
