76 THE ADIRONDACK SPRUCE 
met for the sake of so meagre a crop as would result 
from the present system of cutting at the end of that 
period. 
Many lumbermen are now cutting, from lands lum- 
bered ten, fifteen, or twenty years ago, a yield as large 
as the first cut. As arule, they are cutting to a smaller 
diameter than at first, as, for example, in some cases 
where the first cut was to about ten inches, the second 
cut is removing everything down to five inches. Even 
where the limit is said to have been the same at both 
cuts, and the product the same, it must be remembered © 
that, while no trees may have been taken under ten 
inches ateither cut, many trees over ten inches which 
would now be merchantable at the time of the first cut 
were considered unfit for market. Nor is it probable 
that the cutting to the limit at first was as close as it 
would be now. 
The yield tables have been made in order to give 
definite information as to the production of cut-over 
Spruce lands. They embody the results of measure- 
ments on the 1046 test acres classified according as 
the yield was nearest 1000, 2000, 3000 board feet, etc., 
per acre. They give the number of acres in each class, 
the exact average yield of these acres, and the amount 
of timber which would be obtained in ten, twenty, and 
thirty years after cutting down to ten, twelve, and four- 
teen inches. The number of years which must pass 
before the land will yield exactly the same amount as at 
the first cut is also stated. These figures have not 
been evened off by curves in order to obtain regular
