At the same place I measured a balsam fir - 84 feet high, 15 inches
in diameter at 32 inches from the ground. It had 52 annual rings
and 50 or possibly 52 whorls of branches. The most vigorous upward
growth of the trunk corresponded exactly with the largest growth
of wood in the stump. Thus ring No. 33 was 3/8 inch wide and whorl
No. 33 had over 2 feet of growth, below it on the trunk were others
which had but 6 inches.
On the stump most growth was on north-east side; there it was
9 inches, from pith to bark next on east 8 1/2 inches, on south 8
inches, north 6 1/2 inches, west 6 1/2 inches, least on north-west
side, 6 inches. The most light in this case came from the north-east.
This was in the land of mighty timber.
On Great Slave River, the higher latitude is offset by lower
altitude, and on June 2, 1907, while among the tall white spruce
trees I measured one of average size - 118 feet high, 11 feet 2 inches
in girth a foot from the ground (3 feet 6 1/2 inches in diameter),
and many black poplars nearly as tall were 9 feet in girth.
