Reconnaissance in District 4 



The followhg Interesting notes arc by one of 

 men in charge of reconnaissance in District 4: 



"On this job we have been estimating by forties 

 and mapping en a four-inch to the mile scale, contour 

 interval IOC*. On thie map we locate not only main forest 



es, but also characteristic stands, distinguish commercial 

 and non-coi.imercial stands, take notes on logging, accessibility, 

 lumbering costs, soil, surface, and oilvicultural notes. 



We have been working between 8000 and 9000 feet 

 elevation but the next move will take up away ab've 10,OOC. 

 Gome peaks run over 4000 and are so steep and rugged that I 

 think triangulation for napping and irregular strips for 

 the estimato will be most practicable. V/e use the Forest 

 Service standard hypsometer for obtaining elevations of 

 points triangulated on. By careful compase and hTpsoraeter 

 work we can uasily keep the per cent of error under two, which 

 is good for rough country. 



As a detailed system of records io being kept, we 

 can tell on short notico how much time ia given by each 

 man to novin^, mapping, estimating, camp office (map and 

 estimate) and miscellaneous, also how much of oach type and 

 how many M feet are done per month. A separate sheet showing 

 salary and expenses Is kept and by a little clever manipulation 

 we know how much per acre or per M the work is costing." 



Topographic Surveys 



Their Belation to and Value in Logging Operations 

 The Use of Maps 



The following taken from the July 1 number of 

 the American Lumberman ia a summary of the paper given by 

 W. W. Feed, Superintendent of the Oregon and Eureka Railroad 

 Company, Samoa, California, at the Pacific Logging Conference, 

 Vancouver, B. C.: 



:"r. Peed did not advocate topographic surveys as a 

 panacea for all business ills. While sanctioning them In 

 practical form, he declared that some of the new "efficiency" 

 articles were old principles in a new garb. He could not 

 define a money value for topographic surveys in connection 

 with logging work. He found three main divisions governing 

 the success of logging operations, classifying them in the 

 amount of timber per acre, the physical character of the 

 territory to be logged, and the transportation facilities- 

 all interdependent. 



The speaker went into details of determining the 

 amount of standing timber and much of the character of tho
