194 A MANUAL FOR NORTHERN WOODSMEN 
To travel the boundaries of a square mile and twice 
across it, taking quarter acres each 20 rods as determined 
by pacing, gives about 2| per cent of the area actually 
covered by the estimate, and that percentage can be 
relied upon to give, in land which has any regularity of 
type, a close approximation to the truth. To do that 
and what goes with it, section after section through a 
township, is just about a fair day’s work.

The last two methods described as usually employed 
are alike in this, that in the endeavor to get at a fair sample 
of the country they depend mainly on mechanical arrange¬ 
ments rather than choice. This as a general rule is a 
safe thing to do. There will always be enough things left 
to exercise the best judgment of the estimator. On the 
other hand, neither this nor any other system should be 
followed blindly. If part of the tract is especially valua¬ 
ble, especial pains should be taken with it. As a rule it 
will be found safe to ascertain the area of such tracts and
