along the City Line side of this estate, doubtless what was originally 
a screening hedgerow has become so wild and thickly grown up with 
trees and shrubs that it is now a deep tangle. There is an abundance 
of native plants (such as might be met with in any roadside thicket 
in this region) and common naturalized species like the Crack Willow 
and the Sweet Cherry, but there are also quantities of the Norway 
Maple, the Sycamore Maple and the English Ash—species still rare 
in a naturalized occurrence. Certain of the largest of these individu- 
als no doubt were planted but specimens of all possible sizes from 
seedlings to mature young trees occur everywhere in the vicinity. 
Ancient portions of an Osage Orange hedge may still be detected here 
and there-under the trees and indicate that the plants have arisen 
through natural seeding by birds and wind, there being few more 
favorable habitats for such naturalizing than a neglected hedgerow. 
Among this assemblage of species the Bird Cherry occurs in two spots. 
Near the main entrance gate are three individuals, two of which are 
ten to twelve feet high and quite broad. In another portion of the 
hedgerow, about a city block distant, there is a scattered lot of a 
half-dozen or so specimens ranging from four to six feet in height, 
the largest of which are beginning to flower. 
Another mile distant—to the southeast at Crescentville, a quaint 
old spot in the limits of Philadelphia—there are two individuals 
along Tacony Creek immediately above the main road-bridge. 
They lie at the foot of the wooded slope, growing upon rocky banks 
almost within reach of the water. One is a rather low, spreading 
specimen but the other is a slender tree twenty-five or more feet high 
and when in bloom conspicuous from the nearby bridge. These 
specimens have all the appearance of native species, as far as is 
indicated by their habitat, and would likely be taken for such by the 
unknowing. "There are dwellings in the crest of the slope and possibly 
a certain amount of garden rubbish and yard cleanings has found its 
way down into the woods. "There is also a trail leading in from the 
road and some dumping has occurred along it, from whence a small 
colony of Lily of the Valley has established itself. But it seems quite 
as likely, in the light of later discovered colonies, that the seeds of 
the cherry may have been carried down by the stream. At my first 
visit here, a small girl gathering flowers assured me that there were 
no other trees hereabouts with flowers like these. She incidentally 
inquired what kind of tree it was and I hazarded “a kind of cherry.”
