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 2J-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.

Having completed the estimate of one 2^-acre square, he returns to 

 the flag and paces from this point 20 rods north, which is the cen- 

 ter of the second 2J-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.)
