Forest Survey in Nova Scotia. 205 



notes of the survey and two maps made up the compiled results 

 which were turned in to the lumber company. One of the maps 

 was a topographical plan showing elevations by means of 50 foot 

 contours and also all other topographical features and the survey 

 lines. The other plan was a growth sheet on which were shown 

 the forest types in colors, with written modifications and com- 

 ments upon them. 



Meanwhile arrangements were made for us to continue our 

 work on the 75,000 acre tract which lay to the southwest of the 

 area already done. More men were available for this work; so 

 by the second week in October four crews were in the field. 

 Being farther away from the base of supplies, and necessitating 

 closer co-ordination between the four crews than between the 

 two on the other work, it was advisable to have a regular office 

 to direct the work. Therefore I stayed in Crossburn with an 

 assistant, where we attended to the arrangements for the field 

 force while finishing the maps and reports of the first work. By 

 the time these were done, new data was available in sufficient 

 quantities to keep us busy. 



Three of the four crews were put on the exterior boundaries, 

 of which there were over 200 miles. They were regular six- 

 men surveying crews, as before described. The fourth crew, 

 which besides the six men for the surveying, carried two esti- 

 mators with their assistants and a level crew established the 

 interior base lines and did the estimating. The scheme of the 

 interior survey resembled closely that worked out for the first 

 tract. Base line No. i west of the first survey was prolonged 

 across the northern end of the second tract, and from it three 

 base lines were run south two miles apart to the south boundary. 

 A third base line was run east and west across these as a check 

 line about half way down. Levels were run and bench marks 

 established every quarter-mile on the extension of the Base Line 

 No. I West, and on the first and third base fines running south. 

 The estimators cruised east and west between the base lines and 

 between base lines and boundar}- at intervals of one-quarter mile. 

 The closer spacing was used in this case, as more detailed and 

 more accurate knowledge was required on this area, of which little 

 definite knowledge was in the hands of the lumber company. 



The three boundary crews were able to finish about three weeks
