124 Fourth Annual Keport of the 



Acres 



In the slope type 1,730 .48 



In the ridge type 1,494 . 81 



Burn (slope type) 131 . 57 



Cut-over (slope type) 72 . 18 



Total State land in tract 3.420 . 04 



The actual estimating required two weeks, and an additional 

 day was spent in taking height measurements. Altogether twenty 

 days were spent in field work. If salaries had been paid the men 

 would probably have received an average of $50 a month* and 

 expenses. This is $1.66 per man per day, or a total of $166 for 

 the five men. Allowing a liberal $1 per day per man for subsist- 

 ence, etc., would have made the expenses total $100, a grand total 

 of $266 for 3,429 acres surveyed, or 7.76 cents per acre. For a 

 larger project, bigger crew and less rugged topography, the cost 

 could easilv be reduced to five cents an acre. The cost of the 

 oflice work came to one cent an acre. 



The data were worked up in Ithaca for greater convenience. 

 The estimate sheets were tabulated separately for slope type and 

 for ridge type, so as to get the total number of trees of each species 

 and of each diameter. These totals, divided by the number of 

 acres estimated in each type, gave a stand table, showing the num- 

 ber of trees of each species and diameter on an average acre for 

 each type. (See tables 4 and 6 in forest description.) 



In order to figure the volumes it was necessary to decide upon 

 what volume table to use for each species, to prepare a height 

 curve for the species and then to apply these heights to the chosen 

 volume table by interpolation. For balsam fir Table 41, page 55 

 of United States Department of Agriculture Bulletin No. 55 was 

 used. For hemlock of the smaller diameters. Table 6, page 118 

 of Forest Service Bulletin 36 was used, and for the larger 

 diameters, Table 12, page 124 of the same bulletin. 



For beech, birch, maple and the miscellaneous hardwoods, 

 Tables 2, 5, 7 and 2 respectively on pages 114, 117, 119 and 114, 

 respectively^, of Bulletin 36 of the forest service, were used. For 

 basswood and ash, it was necessary to adopt Table 29 of the forest 



*One party chief at $1,600 per year; four assistants at $30 per month.
