gprin/rled with Bection corners, the usual method of surrey 

 was by carefully running into each unit a base line on which 

 there were established in the center of each row of forties 

 a monument from which the strip surrey was later started, 

 ^e tho topography was very irregular and the exioting 

 /overi-'nent naps practically worthless, a chain was used in 

 measuring distances. The following table is used in making 

 the proper allowance for advances due to changes in elevation: 



Tills column giveo chains actually measured 

 First row of figures (25, 50, etc.) gives difference 

 in elevation. 



Body of table shows the necessary advance. 



Two men, and a large part of the time three, made 

 up the j:c.rty, one man acting as topographer, the other as 

 silviculturist. The third man, in a three man crew, watched 

 the chain and assisted both silviculturist and topographer. 



A careful system of keeping notes in silvics and 

 topography was used, valuation ourvey book Ko. 333 being 

 used for the former and Form 874-15 in a loose binder for 

 the latter. A section per day was averaged for the working 

 *. 1-19 of three men, and little office work was done during 

 the year. It seems a loss of good time to devoto the days 

 of field work to office work, yet it was found all but im- 

 possible later in the winter to & t through with the office 

 work before the next season began. 



The total cost of the work was $1500, resulting in 

 a cost per acre of one cent by traverse and of three oants 

 by regular strip survey 5fi estimate.
