The estimate of the stand of timber on the 

 Reservation proper is based on an actual count on about 

 three per cent of the timbered area and the estimate is 

 necessarily approximate. The valuation survey strips 

 were located through typical country and no offort was 

 made to run parallel lines. 



The ostinato of the Extension and the Lower 

 Allotments is based on the actual count on five per cent 

 of the timbered area* In making the valuation survey, 

 the strips were run in quarter-mile parallels with the 

 river as a base line, so that each row of allotments was 

 bisected by the line. The estimate is nothing more than 

 approximate and no important financial transaction should 

 be based upon it. 



The maps are the first topographical maps and the 

 only accurate maps of the country covered. The original 

 Land Office surrey through the entire tract was an absolute 

 farce. With the exception of writing up elaborate field 

 notes, by far the larger part of the work was never done at 

 all. Occasional corners were found but they seem to have 

 been put in at random and often have no connection with any 

 other corner. Largely for this reason but few of the 

 allotments were actually surveyed out, when the allotting was 

 done, nearly all of them being merely located on papor. 

 It is impossible to locate, on the ground, from the Land 

 Office description, fully seventy-five per cent of the 

 allotments, since the corners and the sections in which 

 they purport to be were never put in. However, the 

 aMotments can bo located very well by using the river 

 as a base from which to start, as was done in this work." 



During August 1909 Forest Examiner Louis Margolin 

 spent about three weeks in obtaining an estimate and taking 

 the data for a topographic map of a prospective sale area of 

 twelve sections on Grizzly Mountain. Mr Margolin worked 

 alone and obtained hio topographlcf.l data by pacing and using 

 an aneroid, the estimate being based on sample plots. 



July 1, 1910, Forest Assistant Jotter and a party 

 consisting of Guard 0. M. Evans, and Field Assistants H. W. 

 Curry and F, 11. Nottage, together with Assistant Ranger 

 wm. X. Garret t, began the first reconnaissance work by party 

 on the main Trinity. 



There were covered during the three and one half 

 months of work 80,000 acres of government land, largely with 



a five per cent strip survey estimate, though for a part of 



the area a traverse survey with sample plots was used. 

 There were also mapped ana roughly estimated 25,000 acres 



of patented land. Since the area estimated is but sparsely
