INTRODUCTION. 



To the Senate and House of Representatives : 



In accordance with the provisions of the resolve authorizing the 

 continuance of the Scientific Survey, we have the honor to present 

 herewith our Annual Report, describing the results of our explora- 

 tions during the past season. 



No change has been made in the organization of the corps of the 

 survey ; but we have been unable to employ all who were in the 

 field the previous year. Mr. Houghton has not been in the service 

 at all, and Mr. Packard only a few weeks ; the rest have been hard 

 at work in the field, some of us from the 10th of May to the 6th of 

 October. Several persons of eminent ability have applied for the 

 ofiice of assistant to the survey, but we uniformly refused their 

 services, and desire to accept no others until we have the means 

 to employ aid in addition to those now on the list. Those who so 

 kindly tendered us their services without charge shall be remem- 

 bered first when we may have the means of remuneration in our 

 hands. 



On the 25th of March we conferred with His Excellency the 

 Governor and the Secretary of the Board of Agriculture in refer- 

 ence to the plan of operations for the season. The instructions 

 then received we have endeavored to carry out in the way now 

 to be described. As before, we formed two parties, each of us 

 either accompanying or having charge of one of them. The 

 Naturalist, Dr. Holmes, spent a part of May, the whole of June 

 and a part of July in exploring the distribution of the Lower Hel- 

 derberg limestone, or the "marble layer" of Maine, in Aroostook 

 county. About the first of July Mr. Fuller commenced to explore 

 the marine zoology of the coast, under the direction of the survey, 

 accompanied by Mr. Packard for a few weeks. He commenced 

 his work near Eastport, and worked his way along gradually to 

 Portland, having amassed a great number of facts and specimens.
