Splitting the 30 stumps so as to obtain from each a sufficient por- 
tion for the sample required the work of 3 men for 3 days, which, 
at $2.50 a 10-hour day, amounted to $22.50. The cost of gathering 
and hauling the 3 cords of wood, requiring the services of 2 men and 
a 2-horse team for three-fourths of a day at $7.50 a day, was $5.62. 
lf special stumping powder, selling for $12.50 a 100 pounds at that 
time, had been used, the powder cost could perhaps have been reduced 
by 20 per cent, or to $30 for the 30 stumps. The labor cost of plac- 
ing the shot holes and shooting the stumps could probably be reduced 
on a steady job. Against this it should be said that to have removed 
all the stumps completely would have required the time of a man 
and a team of horses for an additional day, as well as extra powder, 
fuses, and caps. The labor cost of shooting the 30 stumps should 
accordingly be left at $12.50. To have spht the stumps completely 
so as to recover all the heartwood and permit the handling of the 
pieces by 2 men would have taken the 3 men 3 days more, making 
the cost of splitting the 30 stumps $45. On a steady job with men 
accustomed to the work, provided with tools or equipment that 
experience would suggest, this item possibly could be reduced by 
at least 50 per cent, or, in this case, to $22.50. On the basis of an 
average of 50 per cent heartwood in the stumps, it is estimated that 
at least 3 stumps are required to make a cord of wood, or about 10 
cords from the 30 stumps. To gather up, haul, and load this on the 
car would cost 10/3 times $5.62, or $18.73. Summing up on this 
basis, the cost of these 10 cords of wood loaded on the car after a 
1-mile haul is:

Liberal allowances have been made in the items on which the cost 
of this yellow-pine stumpwood depends, and the cost a cord is con- 
fidently believed to be a minimum one. A material reduction of this 
figure need be expected only from the use of hitherto undeveloped
