ALLEN: 



Our last subject was reconnaissance estimates. If 



thoro is aiT;thiiig further on reconnaissance please ta^:o it 

 up now, 



HILL: 



.. year ago wo got volutie tables on diamater classes 



from Stanislaus (llr.I-Iill tlion slioiroc". mat ho mat ic ally that 

 tlio error involved in measuring trees in 5 in oh diameter 

 classes is less than 1$ as against tally Jag thorn in 1 inch 



clashes. ) 



Discussion* 



.-lien: I suggest that this matter "bo pub 

 in the lianclc of the Resolutions Com. 

 Hoding'jon: Thero is something- Hill had 

 no time to call attention to and I v/ould 

 lif.o to. "7e had an adding machine in the 

 office and "o;7 actual mathematical cal- 

 culations the time saved in reconnais- 

 sance alono, couzfjing out all tho other' 

 worl: in the office paid foi the machine. 

 In tabulating the resuli; s of our forties 

 it was neooscary, of course, for one man 

 to do the tabulating on the machine 

 while the other men callod off the fig- 

 ures from the volume tables. "7e figure 

 * that if possible to do so it would save 



a great deal of tire if the actual vol- 

 ume tablo value data were placed on the 

 40 estimate sheets in printed lorm in 

 one corner of the space for the tabula- 

 tion of the trees; and then when you 

 come int-e-'tlie office instead of wor!d.ng
