forward our researches. Some hotel proprietors refused to accept of 

 compensation for accommodation received ; others reduced the ordinary 

 rates for our benefit ; many occupants of private houses freely tendered 

 their hospitalities ; some have gone with us to point out localities of 

 interest ; and for six weeks so many carriages were placed at our disposal 

 that there was no occasion to hire a team. Every one with whom we 

 came in contact, from highest to lowest, expressed an interest in our 

 work, and no one, to our knowledge, spoke of it disparagingly. These 

 many favors greatly stimulated us in our work. Acknowledgment was 

 also made of the important aid furnished by the newspapers. They 

 promptly circulated our original appeal for aid, and have always been 

 ready to help us subsequently. 



The authorities of Dartmouth college generously provided rooms to 

 serve as an office and working apartment, as well as for the exhibition 

 and storage of specimens, till a building could be erected for their accom 

 modation. Lastly, a few names of individuals were given who had ten 

 dered us special courtesies. 



SECOND ANNUAL REPORT. 



This continues the history from June I, 1869, for one year. It com 

 mences with statements respecting the importance of a new topograph 

 ical map of the state, that might serve for the proper delineation of the 

 geological boundaries. One of the first inquiries made at the beginning of 

 the New Hampshire explorations, related to the character of the maps in 

 use, that I might learn with how great precision the position and courses 

 of the several mineral veins and rock deposits could be delineated. I 

 found that a map had been issued, under the authority of the state, in 1 8 1 6, 

 by Philip Carrigain. This seems to have been a very fair delineation of 

 the natural and civil boundaries at the time of its appearance. But there 

 are serious errors in it of latitude and longitude. Nearly half the boun 

 dary lines have since been altered, whether of the towns, or the limits 

 between adjoining territories; and, moreover, the plates are not to be 

 found. Then the whole face of the country has been altered since 1816; 

 large tracts of forest have been reclaimed and occupied by village sites ; 

 numerous roads and railroads have been constructed, so that Carrigain s 

 map does not meet the necessities of either practical or scientific pur-
