176 Rhodora [SEPTEMBER 
Rhodora does not penetrate to the interior of the wood, but is con- 
fined to the margin from which it has spread into the open areas. At 
one place, the shrub occurs where there is a slight bogginess in spring, 
though it does not attain its best development. At this time — the 
first of June — the locality is quite dry. Following the margin of the 
copse specimens occur more frequently toward the drier ground, and 
are constantly found in association with Cornus canadensis, Diervilla, 
ferns and mosses. On the south side where there is an extended open 
area toward the beach the shrub has passed much beyond the trees into 
the open and dry ground, where it appears to be extending. 
In the open area just described, the shrubs are rarely over 30—40 
cm. in height. On the western side of the woods, it is more commonly 
6--9 dm. high. Here, however, several shrubs were found to have a 
height of 12 dm., while on the southern, western and northern sides, 
they were considerably taller. Careful measurements showed a number 
at least 1.5 m. high, while in one instance 1.6 m. was the result ob- 
tained. A noteworthy feature connected with these variations, was 
observed in the fact that the plants were always smallest in the open, 
while on the edge of the wood, where sheltered by the trees, they 
invariably attained their greatest height and stoutest stems. 
'The second locality studied, lies on the eastern slope of a rather high, 
gravelly ridge near its southern extremity, back of O'Neill's slaughter 
house and just above the Canadian Pacific tracks. The soil is per- 
fectly well drained, and shows no indication of a swampy condition 
at any season of the year. The area was, until very recently, occupied 
by the common alder. Rhodora shows an abundant growth over a 
tract about two by eight rods in extent, but scattering specimens are 
found over three or four acres. None of the shrubs are over 6 dm. 
in height, and they therefore conform to the dimensions usually assigned 
to the species. No other Ericaceous plants occur in the immediate 
vicinity. 
The Protestant Cemetery lies on the summit of a high, gravelly 
ridge opposite Minister’s Island. On the top of this ridge, and within 
the limits of the Cemetery, there is a slight depression occupied by a 
shallow bog which becomes dry in summer, and, even on the first of 
June, shows very little moisture. This basin is about one acre in 
extent. Throughout its entire area, there is a good growth of Iris 
versicolor, and indifferent specimens of Spiraea latifolia. Osmunda 
cinnamonea and Onoclea sensibilis are abundant about the margin.
