of oaks. White oaks predominate in the central portion where the 
elevation is between 131' and 132'. Both to the northwest and to 
the southeast the land rises a little and black oaks replace the white 
oaks. Among the oaks some red maples, a few young elms, and such 
small trees as Betula populifolia Marshall, Populus trernuloules 
Michaux, Primus serotina Ehrhart occur. Although undergrowth is 
sparse except under the white oaks where Viburnum dentatum L. 
grows lushly, such shrubs as V accinium corymbosum L., Amelanchier , 
an occasional Cornus, some Rhus radicans L., V accinium angusti- 
folium Aiton, and Gaulthcria procumbens L., along with a variety 
of herbaceous plants, provide some cover. 
Southeast of the playing field and of the study area is a fairly 
extensive wooded tract. This mixed stand of hardwoods shows evi- 
dence of blow downs and fire damage. As a result, the stand is some- 
what open above and a dense undergrowth of suckers and shrubs has 
been encouraged. Near the eastern corner of the study area is a 
fairly dense stand of gray birch and alders which merges with the 
woodland to the east and with a swampy area on the south. This 
small swamp spreads irregularly somewhat to the northwest. Through 
it runs the shallow brook that drains the tract. Much of the sum- 
mer the black muck of its bed is exposed, but during the wetter 
seasons there is usually at least a trickle of water flowing along its 
course in an east-southeasterly direction. 
South of the brook and swamp there is a gradual rise with patches 
of blackberries (Rubus) and scattered clumps of shrubby oak and 
wild black cherry suckers with intermingled patches of rank herbs, 
grasses, and even occasional areas carpeted with Danthonia and 
Polytrichum or other low-growing mosses. This rather open, shrubby 
growth merges with a denser cover of young hardwoods along the 
property boundary until such growth yields to the open lawn of a 
houselot on the south-southeast margin which bounds on that side a 
fairly level field on that corner of the college property. The field 
serves the neighborhood children as a playground and lies a few feet 
below the level of the road (Hyatt Avenue) which bounds the col- 
lege tract on the south-southwest. On the west a ditch bounds this 
field and beyond it is a wild growth of naturalized garden roses, 
shrubs, and herbs mixed with native plants. Further west the land 
rises to road level and the site of a levelled house has groups of trees 
including Acer negundo L., Juglans cinerea L., neglected apples, 
pears, with broken fields between. Just beyond is our house which 
is surrounded by trees and lawn areas. Behind (or north) of these 
roadside conditions is a marshy field with rank grasses that merges
