PRACTICE OF TIMBER ESTIMATING 



177 



figures obtained gives its timber stand. In well-timbered 

 land two to four " forties " a day can usually be covered 

 by these methods. 



In recording the results of such an estimate the size 

 and quality of the timber are of course noted as well as 

 its amount, and general notes on the growth, topography, 

 and lumbering conditions of the land are also recorded. 

 Following are sample notes of such an exploration: 



Twp. 29 N. R. 7 W. S. E. i of S. E. i of Sec. 8. 

 White Pine, 7 logs average to M. ; 30% uppers 835,000 

 Norway Pine, 8 logs to M. 110,000 



Hemlock, 11 logs to M. 175,000 



Basswood, 7 logs to M. 15,000 



Maple, 14 logs to M. 65,000 



Total 1,200,000 



Land slopes to North. Clay soil; very stony. Two ravines 

 running N. W. and S. E. through the " forty." Tamarack swamp 

 of about five acres in N. W. corner. 



Another method of timber cruising carried out by one 

 man alone is described as follows in the "Woodsman's 

 Handbook " : 



A "forty" is 80 rods square. The cruiser who uses the method 

 now to be described has found by trial that 500 of his natural 

 paces are required to go 80 

 rods. He begins at the cor- 

 ner of a " forty," say at the 

 southeast corner, and steps 

 off 125 paces on the south 

 line, and so covers one- 

 quarter of the side. He then 

 stops and, facing north, 

 counts the trees of the 

 "forty," first to an estimated 

 distance of 125 paces on the 

 right hand, and then to an 

 estimated distance of 125 

 paces on the left hand, and 

 m each case to a distance 

 of 100 paces in front of him, thus including the area represented 

 in the diagram as Plot I. He then steps north 100 paces, and 

 in the same way counts the trees in Plot II, and repeats the opera- 

 tion successively for Plots III, IV, and V. He has then a complete 

 count of the trees on the eastern half of the " forty." He then 

 walks west 250 paces along the north line of the " forty." Facing 

 south, he now counts all the trees on Plots VI, VH, Mil, TK, 

 and X in the same way as before, and thus completes counting 

 the trees on the entire " forty. "
