NOTES TO TABLE 15. 



Table 15 is computed from table 12 and table 8, deducting 

 from the values of logs given on tbe latter all expenses in- 

 curred for converting standing trees into lumber ready for 

 shipment. These expenses, on Mr. Vanderbilt's. property, 

 amount to from $9 to $11 per 1000 feet B. M., according to 

 the circumstances prevailing in the difEerent sections of the 

 huge tract. 



Example: Under average conditions of growth, a poplar 

 tree, which can be logged and sawed and handled at an ex- 

 pense of $11 per 1000 feet B. M. is worth 109 cents at the age 

 of 220 years, and 330 cents at the age of 260 years. 



The market value of a tree is negative, if the aggregate log- 

 ging and milling expenses to be spent on it are in excess of 

 the value of the lumber obtainable from it. 



The following, tables have refearence only to sound trees free 

 from defects. Logically, I ought to give the observations con- 

 tained in these tables for trees with one or two defects, for 

 trees with three to five defects, and for tveles containing cull 

 logs only, as well. However, calculations and mere figures are 

 annoying enough, and I anticipate the wisih of the reader, to 

 have such statements curtailed as much as possible. 



As appears from table 8, the lumber in logs 16 inches 

 through at the small end is worth $8.71 per 1000 feet. 



In logs 17 inches through at the small end it is worth $9.54 

 per 1000 feet. 



In logs 19 inches through at the small end it is worth $10.70 

 per 1000 feet. 



Therefore, where the logging and milling expenses are $9 

 per 1000 feet, logs 16 inches through ought not to be held out; 

 whilst where they are $10, logs 17 inches through, and where 

 they are $11, logs 19 inches through ought not to be cut, their 

 value being negative. 



On the other hand, it appears from the notes to table 12 

 that I included logs of 14 inches diameter when computing the 

 volume of my trees, and the values of ta'ble 15 are based on 

 the same understandmg. It would lead me too far to defend 

 the course actually adopted. Suffice it to state, that the cor- 

 rectness of the folio-wing tables k acaroely afEected by it.
