In planning the 1964 field trips of the 56th Annual Meeting of the New EnglandIntercollegiate  Geological Conference, the Editor and Organizer wished to offer tothe large number of part ic ipants  an opportunity to study features truly representativeof the geology of eas tern  M assach u se t t s .Eight field trips will be presented for a full day on Saturday and abbreviated field trips to the same areas  will be conducted on Sunday. The in teres ted  student o Earth Science may develop for himself a representat ive  composite picture of the geology of the Boston Basin and of the metamorphic and igneous rocks outside the Basin proper by a syn thes is  of information contained in this guidebook. Each field trip leader has presented a general d iscuss ion  of the relation of his area of special study to the geology of the region. He has a lso  presented a d iscu ss ion  of certain deta i ls  of se lec ted  outcrops which have been chosen to i l lus tra te  some of the genera fea tures .  Each has chosen to present the kind of road log which he considers  best suited to a study of the area in quest ion .  It may be noted that two variations in strat igraphic  designation are used by various authors both of which are proper usage; the one approved by the U .S .  Geological Survey for publications by its  members and the other approved by the Committee on Stratigraphic Nomenclature of the Geological Society of America.This printed outline of the geology of the areas se lec ted  for specia l  study by this Annual Meeting is presented with the expectation that it will benefit not only the Conference participants under the personal guidance of the Leaders but a lso  thos geo log is ts ,  teachers  of Earth Science ,  and the in teres ted  public who, in the absence of personally  guided tours by the Leaders,  may wish to use the guidebook to visit  and understand the geological features described herein.The Editor and Organizer of this Conference w ishes  to acknowledge his gratitude to the following persons who have helped in a specia l  way to make the 56th Annual Meeting possible:  Very Rev. Michael P. W alsh ,  S. J . ,  President of theHost Insti tu t ion, who invited the Conference to the Boston College campus; all the highly qualified and busy field trip leaders  from neighboring inst i tu t ions and from the United States  Geological Survey who have generously shared of their time and sc ien t if ic  knowledge to make the geology of this area better understood? Miss Lydia M. McCarthy, Administrative A ss is tan t ,  who attended to the innumerable arrangements connected with a meeting of this size; Miss Maryellen McCluskey, who typed the multiliths of the manuscript for publication and who a s s i s t e d  in coor­dinating arrangements; Mrs. Alfred E. Wier, who a s s i s te d  in proofreading the manu­script; Profs. John J. Rodgers, Yale University and Alonzo W. Quinn, BrownUniversity whose a s s i s ta n c e  with advice and mailing were most helpful; Profs. Emanuel G. Bombolakis, George D. Brown, J r . ,  and Mrs. William Schromm of the Boston College Geology Teaching Staff, and the Geology Club led by President Charles G. Legarde, who were most helpful in connection with the field trips them­selves;  Rev. Francis B. McManus, S. J . ,  Secretary of the University ,  and his staff,  who handled the campus arrangements; and all the many others who a s s i s te d  in many ways.
