TIMBER ESTIMATING, 69 
He then paces 5 rods south and then 5 rods west, which brings him 
to the center of the southwest quarter of the square. He estimates 
this small plot and then paces 10 rods north, where he stands and 
estimates the northwest quarter of the 24-acre square. He then 
paces 10 rods east and estimates the northeast quarter of the square, 
and then paces 10 rods south and estimates the southeast quarter. 
Fig. 1.—The method of cruising by dividing a “‘forty’”’ into 16 small squares. 
Having completed the estimate of one 24-acre square, he returns to 
the flag and paces from this point 20 rods north, which is the cen- 
ter of the second 24-acre square, which he estimates in the same 
way as before. This operation is continued until four squares have 
been estimated. The cruiser then takes in hand the tiers of 
squares directly east of the first series until the 16 squares, or the 
entire ‘‘forty,’’ have been covered. (See fig. 1.)
