Contributions To The Geology Of Eastern Massachusetts Classic Reprint

Excerpt from Contributions to the Geology of Eastern Massachusetts Early in the summer of 1875 I began a systematic study of the rocks in this vicinity, with the view of collecting such data as, added to my previous knowledge, would enable me to prepare a thesis for graduation in the department of Natural History of the Massachusetts Institute of Technology, on the "Geology of the Environs of Boston." In the beginning of the following winter I was charged by Prof. A. Hyatt, under the direction of the Massachusetts Commission to the Centennial Exhibition, with the task of preparing a geological map of the State, for exhibition at Philadelphia. Opportunity was afforded me by the Commission to visit all parts of the State. The Boston Society of Natural History generously permitted the use of my time as assistant in their Museum for this purpose, and, as that winter was unusually favorable for exploration, I was in the field almost constantly. The Centennial map and the report on the same were completed in the following spring. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Geology of the Boston Area, Massachusetts The area herein described, which lies between parallels 42° 15' and 42° 30' and extends westward from the shore of Massachusetts Bay to meridian 71° comprises the Boston and Boston Bay quadrangles and has a land area, including marshes and islands, of 240 square miles. It is situated in eastern Massachusetts (see fig. 1) and includes nearly all of Suffolk County and parts of Middlesex, Essex, Norfolk, and Plymouth Counties. The city of Boston occupies the south-central part of the area. In this bulletin, for convenience, the two quadrangles will be designated by the term Boston area. This is not the same as the Boston district, which comprises the Boston Basin and the adjacent territory in which the geology is closely related, so that it forms a sort of unit having distinctive geologic characters that differ in some respects from those of the surrounding areas. The limits of the Boston district are not well defined, but it extends several miles outside the Boston area on the north, southwest, and south and includes about twice as much territory.
