PRACTICE OF TIMBER ESTIMATING 
185 
in Massachusetts, having considerable value and a varied 
stand of timber, will illustrate the different methods of 
timber estimation and the way of going to work in a par¬ 
ticular case. This tract was mapped topographically. The 
methods employed for that purpose are described in Part 
II and a complete map of the tract is given on page 114. 
The steps contributing to the timber estimate are as follows: 
a. Boundaries run out to get area; chainage marks left 
at frequent intervals. 
b. Some 65 M feet of heavy and valuable pine timber cal¬ 
ipered tree by tree; numerous heights measured; con¬ 
tents ascertained from volume table. 
c. Three bodies of thick young pine circled by staff 
compass and pacing to get area. Average stand of each 
bunch ascertained by laying out quarter-acre sample plots 
representing 10 to 20 per cent of the area. Trees on these 
plots calipered; heights measured or estimated; contents 
taken from volume tables. 
d. Ten acres of hard-wood swamp in north end esti¬ 
mated for cord wood by similar but quicker methods. 
e. Balance of 60 acres of ground is covered with scatter¬ 
ing pine and hemlock, chestnut fit either for box boards 
or railway ties, poplar, red oak, and other hard woods. 
Northerly 37 acres considerably better than the other 23. 
Ran strip surveys across the two parts representing 10 per 
cent of the area, running the strips across the ridges 
and the belts of timber. Calipered the trees into classes 
of pine, hemlock, chestnut, poplar, hard woods fit to saw, 
and cord wood; estimated saw contents from tables, such 
as were at hand, adjusted to the locality and practice, 
with due reference to heights; estimated cord wood from 
tables, experience, and judgment. 
The field work involved in steps b, c, d, and e represented 
one day’s work for four men. Result was the following:
