Alav. 1932) SURVEY OF FREMONT AND BOSCAWEN 7 



The smaller ownerships are naturally found nearer the villages. 



The boundary lines consist of stone walls fences, brooks and 

 roacR n most-cases boundary lines are ^yell ^efined^the exceptions 

 beino- where lots ^yere subdivided and portions sold oE without being 

 marked Generally, the boundaries between timber lots are recog- 

 ni7al)le by the variation in timber growth even though there are no 

 walls or fences. The large number of stone walls helped greatly in 



making this map. 



Probably the most important factor in the low cost of the survey - 

 was the fact that property records were collected in the offices ql 

 local surveyors who themselves knew the town very well and were 

 willing to help in every way to build the map. 



METHODS 



Fremont , . , 



The first step in each survey Avas to make a base map which 

 showed the position of the roads, railroad, main streams, houses, etc. 

 Then the distribution of ownerships had to be determined, and later 

 entered on the map by plotting or field work. After that was com- 

 pleted, a final map had to be drawn. 



For the base map of Fremont, on which the final paced map was 

 built the Pawtuckaway sheet of the U. S. G. S. topographical sheet, 

 enlarged to the scale of eight inches to the mile, was used for the 

 northern third of the town. The Haverhill sheet, covering the 

 southern two-thirds, was not accurate enough m detail, so a 

 traverse-board map of the roads and railroad had to be run out as a 

 base for this area. This took about a week, but was mdispensible. 

 Since then, work has been completed for a more accurate map to re- 

 place the old Haverhill sheet. „wri- 

 The special problem of the Fremont survey was to hunt out the 

 property lines. Even in the areas where the lines were well known, 

 it was necessary to trace them out in some way with someone 

 acquainted with the country before any mapping ^ould be done^ 

 Where thev were not definite it was necessary to search for all the 

 evidence available, in the form of records as well as on the land it- 

 self, before mapping. c^^nrino- the 

 Several sources of information were offered for securing the 

 necessary fac s. The most dependable and satisfactory was to go 

 ZtoTXn<l with someone who knew the -untry, follow out som 

 of the lines see important corners, and generally get the lay ot the 

 \LT Then with a sketch of the property division as a guide, it was 

 not difficult to pace out the map. The willingness of the townspeo- 

 ple to take time for this work is greatly appreciated. 

 ' Some of the areas were covered by plans P^-^^^ncW a few- 

 surveyor's descriptions taken from deeds After finding a few 

 points'^on the ground which were represented on ^^^^ ^f^^V M 

 fairlv easy to check the rest, and transfer them to the map. i^u 

 uc^'pTan's 'had to be checked, however, for the data given m the 

 deeds on which they were based were rarely complete as to dn^ec 

 'i^ns and distances. Also, the compass directions were not strictly 

 dependable, since these were based on magnetic and not true, north, 

 and the magnetic declination changes appreciably in a few years.
