1918] Long,— Eragrostis peregrina 177 
plants were discovered in the fine cut-stone forming the concrete- 
curbed platform about the railroad station. Search failed to disclose 
the species on either the tracks or the adjacent roadside. 
During early autumn a center was made at Beach Haven, and in 
travelling back along the railroad to botanize at various points a 
plant or two was detected from the train at Barnegat, on the freight 
siding opposite the Pennsylvania Railroad station —so character- 
istic-looking that the identity was felt to be almost certain. Investi- 
gation showed E. peregrina to be fairly frequent about the tracks, 
apparently occurring only on the sandy railroad bailast, however, 
and not on the roadsides. Barnegat is also the terminus of a branch 
of the New Jersey Central. On the freight sidings of the Central 
tracks, near by but not connected with those of the Pennsylvania 
Railroad, the plant was found to be a dominant weed, growing luxuri- 
antly in the open as well as in the shade under standing cars, the 
station platform, and taller weeds. 
Barnegat having produced the plant, the terminus of the Penn- 
sylvania system at Beach Haven on Long Beach Island was thought 
likely to show another locality. The tracks and the railroad yard 
here are upon a considerable fill, largely of rather clean cinders, and 
. situated almost entirely over salt marsh. Very few weeds of any 
kind were about the tracks and no Æ. peregrina. Further search was 
rewarded by finding it about South Street and the Boulevard in the 
central part of Beach Haven. Here it was noted as locally frequent 
on the sidewalks, but most abundant in the hard, exsiccated “ gutter” 
region of the gravelled streets. 
Specimens having been seen from the ballast-grounds of Phila- 
delphia, a sharp lookout was kept for E. peregrina when another quest 
-took me to the long neglected ballast region of Kaighn’s Point, Cam- 
den. Within sight of the Kaighn’s Point Ferry it was almost immedi- 
ately detected along the weedy sidewalks of Kaighn Avenue. At this 
spot it was apparently rather rare, but along Ferry Avenue, not far 
distant, it grew luxuriantly on waste ground, associated with other 
widely distributed weeds. 
It is readily distinguished along the tracks of the Reading system 
near Kaighn’s Point, as one goes out by train from this terminal, but 
it soon drops from sight as the railroad yards and waste places are 
left behind, and the natural county is reached. 
Extending out from Kaighn’s Point for about a dozen miles, in a
