of trees on the sample acre was cotmted and the average 

 tree guessed at by diameter and height. With a volume 

 table the contents of the sample acre wero computed. The 

 otand for an entire forty was obtained when the end of the 

 forty was reached, by considering the number of acres on 

 the forty that were stocked, and according to the showing 

 made ty each sample acre taken. The totals in thousands 

 of board feet were recorded by species. 



Probably the most important factor in securing 

 a fair decree of accuracy in thfe work was the sample forties. 

 A few tines during the summer, at the beginning of the work, 

 and later when a distinct change in the general type of 

 forest encountered gave a new set of conditions, representative 

 sample acres were laid out with compass and chain. The 

 toundarios were blazed and then the contents per acre and per 

 forty guessed at by all and recorded. Kext strips one or 

 two chains wide were run through the middle, north and south 

 and east and west, with all trees on the strip oallpered. 

 After the running of each, new guesses were made by all, both 

 of the stand per acre and per forty, and recorded, then the 

 calipered strip was figured in the field with the volume table. 



VThile calipering the individual trees, guesses 

 would be made of most of the diameters before reading the 

 calipers, these guesses bo ing made at varying distances. 

 Then, perhaps, further strips would be run through the 

 forty, five chains in from the corners, two o trips running 

 through oast and west, and oven a further two, north and 

 south, as the irregularity of the stand and the results 

 of the work demanded. With this went the revising, as 

 thb individual deemed necessary, of oach former estimate 

 before the figuring of the succeeding strip. All this of 

 course being tempered by the Judgment of the head of the 

 party, who conducted such work, as to the degree of exactness 

 to which it was desirable to carry the operation. 



This account refers wholly to work done by the 

 writer in the summer of 1910 as Field Assistant working in 

 the base line orerr and at estimating.

Reconnaissance as 1^ gee It 



Reoonnaisnanoo is great work, though it is hard. 

 1*11 admit that at first the only redeeming features I 

 recocnized were tho huge meal at evening and the rest which 

 followed. Kow, however, my viewpoint has changed somewhat, 

 and I consider something besides the purely physical aspect. 



To be away fron all that is dirty and sordid, to 

 rise early and work late, to live close to Fature - in this 

 alone there is enough to make reoonnai usance worth while. 

 Vhilo we may fight throu^i brush and sweat torrents, there
