[May 4, 
The time taken up in bringing the boat home from Bucksport, 
Maine, and in fitting her out, lessened very much our opportuni- 
ties for dredging. 
The Custodian accompanied by Mr. Henshaw, Assistant in the 
Museum, Mr. E. G. Gardiner, Mr. Ed. Warren, and Mr. Arthur 
Winslow, all students of the Institute of Technology, made a trip 
of three weeks duration along the coast of Maine to Head Harbor, 
about thirty-five miles east of Mt. Desert. The results of this 
expedition were very satisfactory. 
Dredgings were made in over a hundred fathoms of water off 
Head Harbor. The distance from land, however, the prevalence 
of fogs, and liability to interruptions from storms, made it evident 
that steam power for handling the dredge would be needed in 
order to make such expeditions as profitable as they ought to be. 
The Arethusa was detained at the Island of Matinicus five 
days by fog, but the time was profitably spent in shore collecting 
and in making a preliminary survey of the geology of the group. 
The results of this labor are now being digested by Mr. Crosby 
and will be eventually given in the Proceedings. 
Mr. Van Vleck remained in Annisquam all summer, and made 
a number of valuable dissections and preparations for the Mu- 
seum. 
REPORT OF MR. BURGESS, SECRETARY. 
The Secretary respectfully presents the following report on the 
departments under his charge. 
Membership. 
The number of Corporate and Associate members one year ago 
was four hundred and fifty-one. During the past year twenty- one 
Associate Members have been elected, and seven Associates have 
been elected to Corporate Membership. From these classes, the 
Society has lost twelve by death and three by resignation. The 
present active membership is, therefore, four hundred and fifty- 
seven, a gain of six. 
Eight Corresponding Members have been elected during the 
year.
