recorded in the abo\e experiments could be obtained on a fairly large 
scale in the forests by sowing broadcast, without fencing of any kind, 
and under varying conditions of overhead light. This was the object of 
the present experiment. 
39. The areas utilized were : 
Plot XVII .—The cleared strip 300 feet long by 60 feet wide, 
running north and south, mentioned in experiment V above. 
The strip was cleared in 1915. In the present experiment 
the area utilized was that lying outside the central fenced 
area which contained the sowings of 1915 and 1916. 
Plot XVIII .—The cleared strip 300 feet long by 100 feet wide, 
running north and south, mentioned in experiment V above. 
The strip was cleared in 1915. In the present experiment, 
the area utilized was that lying outside the central fenced 
area which contained the sowings of 1915. 
Plot XXV .—A strip 210 feet long by 60 feet wide, running north 
and south, in the forest immediately adjacent to Plot XVII. 
The overhead cover was left intact, but all the undergrowth, 
shrubs and small trees forming the second storey were cleared 
in May 1917, thus lessening the shade considerably, a general, 
view of this plot, from the south, is seen in Plate VII, Fig. 1 
which gives an idea of the number of trees left on the area. 
Plot XXVI .—A strip 210 feet long by 60 feet wide, in the forest 
immediately adjacent to Plot XVII, running north and 
south, and precisely similar to Plot XXV except that, in 
this case, in addition to removing all the undergrowth, the 
main overhead cover was broken by thinning out the large 
trees, an average space of about the diameter of one crown 
being left between the crowns. A general view of this plot 
from the south is seen in Plate VII, Fig. 2. 
The trees and shrubs were cut in Plots XXV and XXVI from May 
11th to 27th, 1917, and at the same time the dead leaves and debris on 
the soil were swept off. As the strips XVII and XVIII had been cleared 
in 1915, a fairly heavy weed growth had established itself, especially 
in Plot XVIII, before the present experiment was started. All such 
weed growth was cut and left to lie on the ground for a month before 
this experiment commenced, in order to weaken the growth as far as 
possible. The cut growth was then removed by hand in the first week 
of June 1917. Each plot was divided into 4 sub-plots, by lines running 
east to west across the area, which were numbered I-IV commencing 
from the north. Each sub-plot was again sub-divided into 3 equal parts, 
by lines running east to west across the area, which were designated
