As soon as the assistant reports that he is ready I take the 

 nearest tree and put the calipers upon it at a point where it would 

 be cut in ordinary logging operations. I then walk around the tree 

 and "size it up " generally to find any defect that may exist, also 

 to judge how many 16-ft. logs would be cut from this particular 

 tree. Suppose it is a maple and that it calipers 22 inches, and that 

 it will yield a 48-ft. stem or three 16-ft. logs. I call to my pacer 

 "Maple, 22 3," and he tallies in the maple column opposite the 

 22 3 of the figures in the left-hand margin of the page. In this 

 way we get a record of every tree in a strip 4 rods wide, 2 rods each 

 side of our compass line. My calij>er blade is graduated to 57 

 inches from the stationary arm, just ^th of two rods, and if there is 

 any question as to a tree's being in the strip it is very quickly set- 

 tled by taking seven lengths of the caliper blade as I walk toward 

 the tree from the compass line. 



Having taken the trees to a point a little in advance of my as- 

 sistant, he proceeds on for 50 paces more and the calipering process 

 is repeated. If the undergrowth is of sufficient density to prevent 

 our seeing any large pine, bit of cedar swamp, or anything else 

 that we should see, we make frequent explorations from the end 

 of each 100 steps, my assistant going in one direction at the same 

 time that I go in the opposite. No trees are measured in these 

 side explorations unless we find something that is not common to 

 the entire tract. Having returned to our line we proceed north, 

 halting at each 50 steps to take the timber, also to note any ridges, 

 logging roads, streams, springs, or other points that should appear 

 in the report. When we have arrived at 500 paces my assistant 

 changes his tally to lot 9 and we proceed north in the same way, 

 changing at 1000 paces to lot 8 and at 1500 to lot 1. At 2000 

 paces, if the section is "full" we should be at the north line of the 

 section, at a point 20 rods west of the northeast corner. As it 

 rarely occurs that our compass line has been so accurate as to 

 bring us out at exactly this point, we find the mark made during
