Tho area osti mated was extremely rough and 

 inaccessible, v.'ith many brush covered slopeo all combining 

 to tring up the cost per acre, as well as to reduce the 

 average per day. 



y 15, 1911, reconnaissance was begun on the area 

 to the north of Hayfork Creek and has up to the present been 

 carried to the source of this creek. 



One of the very pleasant features of reconnaissance 

 work lo the opportunity to associate with bright young nen 

 from the various forest schools. This was particularly 

 the cane this year, when six colleges were represented by 

 the following nen in the party: 



Forest Assistant Jotter, Ohio State University and 

 Univoruity of Michigan; Guard 0. M. Evans, University of 

 Llichican; Forest Aociatant Howard de Forest, Prlncoton and 

 Tale; Field Assistants liarry Tales, Roy Holeman and Rufuo 

 Holland, University of California, J. Russell Bruff, University 

 of Nebraska, David E. Harrower, State College, Pennsylvania, 

 Otto W. Fflueger, Ohio State University. 



The territory covered was similar to that of last 

 year and the methods differed little, except where the nature 

 of the country and the experience of the past year suggested 

 changes for the botter. The topography of part of the area 

 and the experience gained in mapping, showed that chaining 

 need not be done entirely, so that pacing is usually done in 

 coming back to the base line. Instead of a regular chain, 

 a stool tape 66 feet long io taken, the fears that this tape 

 would' broak having proved groundless. 



Trro man parties, sometimes three or one, as the 



occasion demanded, do the work. The topographer carries 

 a form 3C5 township plat and on this shows streams and 

 ridges, the contour lines be ing put on a four-inch map at 

 camp. Elevations are taken by the aneroid and courses of 

 streams and ridges carefully notod. The map is considered 

 a most important part of the reconnaissance work, for while 

 typos and stands may change, only an upheaval will require a 

 new map. A four-inch to the mile scale map is made since 

 a map of this scale can be used for any purpose. The idea 

 is constantly kept in mind that this map is not alone for 

 the reconnaissance work, but is to be used for any of the 

 various purposes that require a map. 



The silviculturist carries a form 525 township 

 plat on which he keeps record of hio forties, a form 328 

 on which he puto the cover, ar,i a form 321a for the diameters
