One of the main routes of exit from Philadelphia into the woods and 
green fields of the northern part of the city and the adjacent suburbs 
is 5th Street. On Sundays and fine days in spring there are few of 
the city ramblers who do not have bunches of violets, or buttercups, 
or what not. Beyond Fisher Park, near the corner of 5th Street 
and Green Lane is a Bird Cherry which, when in bloom, rarely escapes 
the bouquet-makers. In its season it is a mass of flowers and so 
conspicuous that it constantly attracts attention. It stands on the 
roadside, rather in the open, and has had opportunity to develop 
into a handsome, full-branched, symmetrical specimen fifteen feet 
in height. It has a shrubby habit, with numerous main stems, in 
consequence, doubtless, of having been cut down close to the ground 
at some time. Along with nearby scattered pears and apples un- 
questionably it has arisen spontaneously. 
Much of this area is “the old Fox Estate" and is a region of home- 
steads now long gone to decay and ruin. The origin of the Bird 
Cherry here seems traceable to these old places. On the corner 
opposite to the shrubby specimen is a dilapidated house, and in what 
must have once been the yard are several of the cherries of varying 
size. One aged specimen is possibly a remnant of the planted shrub- 
bery but the others are smalland so disposed in the woods and thickets 
as to appear spontaneous. 
East along Green Lane is another place on the Fox Estate where 
there must have been a homestead. Two large Horse-chestnuts 
suggest a gateway at one spot but the house has long disappeared 
and many acres are overrun by Black Locust and Wild Black Cherry, 
while the ground is carpeted with Star of Bethlehem. "The Empress 
Tree, the Washington Thorn, and the Norway Maple have become 
extensively naturalized, and here one may readily pick out the Bird 
Cherry scattered through the woods. This old place extends east- 
ward to New 2nd Street. Along this old road (with a new name) 
at the edge of a wild tangle of native species, thorn and Japanese 
Honeysuckle is a two-stemmed, spreading specimen of the Bird 
Cherry nearly twenty feet across. It seems very unlikely, despite 
its size and age, that it should have been planted in this position; 
it appears to have arisen from natural seeding. 
A mile or more beyond the area of the old Fox Estate is another 
station for the Bird Cherry near the James Fisher place in Montgom- 
ery County, to the east of Oak Lane, Philadelphia. For some distance
