VALUATION SURVEYS. 
{N making a working plan, the first step is to determine 
the amount and condition of the growing stock. In 
order to do this and to obtain data which would permit 
the prediction of future crops, the trees were counted 
and measured on 1046 acres on different parts of the 
Park. Since there are approximately 27,533 acres in 
Ne-Ha-Sa-Ne Park, not including the lakes and the 
tenced portion, these measurements cover about one in 
every twenty-eight acres, and supply the basis for a 
very thorough acquaintance with the standing timber. 
Each acre was run out in a strip ten chains long and 
one chain wide. The length was actually chained off 
in every case and all the trees were measured for one- 
half chain on each side. The latter distance was either 
chained, paced off, or estimated. The measuring crew 
speedily became expert in. estimating the distance at a 
glance. The sound Spruce was callipered down to two 
inches and the smaller trees were counted. Other 
species were callipered down to ten inches when ap- 
parently perfectly sound. 
The strip method (or chain method, as this modification of it is 
called) has the advantage of giving a very fair representation of a 
large area, because it traverses so much ground. Square acres, 
where the lines and corners are carefully measured, are more ac- 
curate for single cases, and a number were taken for illustrative
