e Railroad embankments. The Pennsylvania Railroad 

 from Onoville to Cold Spring is ballasted with broken or 

 crushed slag and in some places with cinders. As in most 

 sections of the State there is to be found along this stretch 

 of track an interesting number of migratory plants, mostly 

 from Europe, which have arrived by way of the railroad. 

 A walk along the railroad from the vicinity of Quaker 

 Bridge station to Cold Spring will reveal a fairly large 

 number of these more recent additions to our flora, some 

 of them scarcely more than adventive, others now well 

 established in many places other than along the railroad. 

 The following list includes only the species growing be- 

 tween the ties along the railroad or upon the sides of the 

 slag and cinder ballast. A few native species seem to have 

 found a favorable habitat here along with the migrant 

 species and they are indicated by heavy face type. It is to 

 be expected that other native species will also be found oc- 

 casionally in such places but their number, like that of the 

 adventive and naturalized species, varies with the degree 

 of cleanliness maintained by the railroad. A more ex- 

 tended search of the railroads, especially about Salamanca, 

 would doubtless yield a substantial addition to this list. 

 Allium canadense was noted in cinders at Riverside 

 Junction.
