We were in the midst of an exceptionally prolonged Yarmouth 

 fog, and it was not until August 4th that we had a sufficient quantity 

 of " toasted " driers to carry the accumulated collections safely through 

 press. On that day, however, all four of us made excursions into 

 the edge of the barrens in the eastern section of Argyle; Long and 

 Linder trying the area near Argvle Head, White and I going on to 

 the extensive barren between Low r er Argyle and Goose Lake. 



After passing through ordinary spruce woods, White and I came 

 upon the dryish sphagnous border of the barren, at this season domi- 

 nated by Bakeapple, Rubns Chamacmorus, which had not fruited 

 well, Carer oligospermia, Gaylussacia dumosa, var. liigeloviana, Em- 

 pctrum nigrum, Ilex glabra, and Calamagrosfis Pickcringii, var. 

 <l chilis, with Habcnaria blcphariglottis scattered everywhere. Toward 

 the wet center of the boggy barren there is a series of shallow pools, 

 where in spring a considerable stream must flow. The borders of 

 these pools are marked by the most spectacular growth of Pitcher 

 Plant, Sarracenia purptirea, we had ever seen, while the open mucky 

 spots were brilliant with solid carpets of Utricularia cornuta; and 

 the pools themselves were often filled with the coastal plain Scirpus 

 tvbterminalis and Potamogcton Oakesianus. East of the central 

 pools the barren becomes very dry, carpeted w r ith Cladonia rangi- 

 fcrina. Corcma Coiiradii, Empctnim, Scirpus ccspitosvs, var. callosus 

 and other such plants of dry heaths; and it was while here collecting 

 Bartonia virginica and that puzzling little Mclampyrum of northern 

 bogs, that we came upon Schizaca pusilla, this time growing in hollows 

 of the Cladouia carpet. 



Goose Lake itself proved very uninteresting, bushed close down 

 to the bouldery shore, so that we started back toward the railroad 

 by a new route and quickly found ourselves in an extensive quag- 

 mire, where the particularly interesting plant was Xyris montana,

 specimens with elongated racemes frequently found in the South and Southwest" —
