36 THE LOG OF A TIMBER CRUISER 
tion plat, four by four inches, ruled into sixteen 
squares representing forty acres each. At the top 
of the page space was given to note the number of 
the range, township, and section, the name of the 
watershed, the date, and the initials of the cruiser. 
On the righthand sheet was the form in which tim- 
ber estimates were set down—sixteen squares cor- 
responding to the forties of the section plat whereon 
the map was to be made. Below, at the bottom, .

some trouble, though, at first. About the best way
