smaller and the herbs more numerous than elsewhere. South- 

 ward the arborescent species of oaks become larger and more 

 numerous and gradually crowd out the pines. The northern 

 boundary of the pine-barrens seems to be more sharply defined. 



The average appearance of the dry pine-barrens is illustrated 

 better by the accompanying photographs * than it could be by 

 any description. The pines are the dominant feature of the land- 

 scape, and the underbrush consists chiefly of a dense growth of 

 two shrubby oaks.f all the individuals of both reaching approx- 

 imately a uniform height in any one locality. The herbs are more 

 numerous in species, but more scattered and inconspicuous. The 

 dry pine-barrens have probably always been subject to occasional 

 fires, which since the advent of civilized man have become fre- 

 quent enough to kill a good many of the pines but otherwise have 

 perhaps caused little change. 



The species observed in this habitat in the two towns men- 

 tioned are as follows. They are divided first into trees, shrubs, 

 and herbs, and then arranged approximately in order of abun- 

 dance in each class.

* None of the existing local floras of I-ong Island is illustrated, so far as known 

 to the writer, so these may be the first photographs of Long Island pine-barren vege- 

 tation ever published. 



t These two oaks are remarkably similar in appearance, considering that they be- 

 long to different sections of the genus. See in this connection Rehder, Rhodora 9 : 

 61. 1907.
