ridge which points toward the sharp 
bend of the creek. Three horizontal 
count strips were run on the northwest 
and three on the northeast slope, cover¬ 
ing the upper, middle, and lower parts 
by separate tallies. The counts have 
been summarized in Tables VII and 
VIII. 
Natural restocking is, in most cases, 
less than 200 seedlings to the acre, 
this number being exceeded on the 
lower northeast slope only. This is 
much poorer than anticipated. It is 
encouraging, however, to note that 
white pine shows a higher percentage 
in the reproduction over that of the 
previous stand. 
The age classes of the seedlings show 
that the greater number are more than 
7 years old, indicating that these older 
ones may have come from seed in the 
soil or duff. The better restocking 
found on the lower part of the north¬ 
east slope contains many seedlings 
from 1 to 4 years old. These appear 
where much typical vegetation such as 
accompanies white pine forests occurs, 
as species of Tiarella, Coptis, Asarum, 
etc., and where the soil is deeper and 
and more moist than on the southwest 
Most of this seed came from green 
trees now extant on the flat toward the 
eastern portion of the area. The 
source of the miscellaneous younger 
seedlings found promiscuously over 
the area is most likely the old un¬ 
burned forest to the southwest. Fresh 
and clean seed coats found underneath 
several 1-year old seedlings of white 
pine, hemlock, and Douglas fir point 
to dissemination of the seed by the 
wind and not storage in the soil. The 
exact relation of this dispersion of seed 
to green timber, has not been traced 
out, and as far as the strips were run 
toward this green timber no migra¬ 
tion or relation was made evident.
