In such estimates poles are merely counted ; the number 

 of ties follows from the number of trees, i.e., the estimator 

 decides that the trees which would naturally be cut for 

 ties generally cut three, four, etc., ties ; while figures for 

 cord wood and posts are 

 usually mere guesswork, 

 which have value only 

 when they come from a 

 very experienced man. 



Where a large piece, say 

 a forty-acre tract, is to be 

 estimated, and the timber 

 is at all valuable, it is best 

 to work in an orderly way. 

 We find the corner A and 

 go along the line AB ten 

 rods ; then we go north ten 

 rods to station No. 1. Here 

 we put down our staff so 

 that we keep the right spot, for there are no fences or other 

 convenient landmarks to guide us, and then we begin to 

 count and estimate all the trees in the square of which 

 this station is the center. If we go four times through 

 the forty-acre tract, this square contains yt = 2| acres. 

 All we learn about this square of two and a half acres 

 we put down on a separate page of our notebook, so that 

 when we have finished the square, or this station No. 1,
