30 Forestry Quarterly. 



The field work was done by the members of the Board assisted 

 by two field parties. Each of the latter consisted of four men 

 with equal representation of the State and Forest Service. As 

 the work done by the field parties formed the basis of the work 

 done by the members of the Board, such will be described first. 



Each crew organized itself into a compassman whose duty it 

 was to maintain a straight and correct course as well as to handle 

 the front end of the chain ; two caliper men, who made diameter 

 measurements of all trees; and a tallyman, who recorded the 

 measurements called ofif by the caliper men. A section formed 

 the unit for the field work. Owing to the area to be covered, it 

 was impossible to make measurements of the entire area of each 

 individual section and, therefore, a valuation survey of but a 

 certain percentage of each section was made. A 2^-per cent. 

 measurement was made on sections where there was a uniformity 

 of conditions throughout, and a 5 per cent, measurement w^is 

 made in all others. In addition to the above measurements, 

 complete notes on the topography ; character of land whether agri- 

 cultural, grazing, or suitable for timber growing only; nature of 

 the ground cover ; occurrence of streams or springs ; wagon roads ; 

 trails ; and all other information that had bearing on the value of 

 the land involved were made, as well as a sketch map showing 

 graphically the individual sections and serving as a necessary com- 

 plement to the field data recorded. 



The thoroughness of the field work and the completeness of 

 the data recorded was of value not only in making possible the 

 exchange, but will also serve a valuable purpose in the prepar- 

 ation of subsequent plants of management of the lieu area on the 

 part of the State, as well as for the National Forest within which 

 the surrendered school sections occurred, on the part of the 

 Forest Service. 



The members of the Board on their part made personal exami- 

 nation of the areas involved and agreed upon the figures of value 

 used in the valuation. 



Owing to the nature and difference in the various factors that 

 go to make up the values of the individual sections consisting of 

 mature timber, young timber and reproduction, agricultural, graz- 

 ing, and timber land, it would have been an impossibility to select 

 an area that would by individual sections correspond to the indi- 

 vidual sections surrendered. Hence it was considered that the
