dunes but growing in the crevices of a rocky headland along with 

 Smilacina stellata, which we had also failed to see on the dunes. 

 In a boggy thicket we were somewhat surprised to find the tangle 

 of Ledum groerdandicum (subarctic) and Ilex glabra (Louisianian) 

 stretching above our heads, and specimens of the Ledum which wo 

 collected show the trunks and main branches to be practically 2 m. 

 (19.5 dm.) high. 



In the afternoon Bissell and Graves went to the mouth of Broad 

 River, returning with Conioselinium chinensc from a patch of rich, 

 old woods, and bringing in the largest Bartonia virginica of the 

 season (3 dm. high). 



Long, Linder and I spent the afternoon near Port Joli (pronouncde 

 Jolly) following a supersaturated corduroy-road back to Louis Lake, 

 which had been described to us as shallow and "full of weeds." The 

 border of the lake proved to be a quaking bog and, without a boat, 

 we were forced to content ourselves with merely imagining all sorts 

 of exciting things in the swimming mass of vegetation. The Ilex 

 verticillata in the bog had densely pubescent leaves, var. padifolia, 

 which we had not known east of Massachusetts, and the bog itself 

 was the home of Arethusa, now abundantly fruiting and a welcome 

 sight in view of its rapidly approaching extinction in the eastern 

 states. 



Next morning there w r as time for some short local tramps before 

 the early afternoon train back to Yarmouth, but the only striking 

 novelty was Crataegus Jonesae, one of the most definite of species, 

 supposed to be confined to the Maine coast, brought in by Bissell 

 and Graves from the shore east of Port Mouton. 



The G raves's time was getting short and there were too many 

 things to do, so it was necessary to crowd the program. We were 

 planning another trip away from Yarmouth, to start early on the 

 morning of the 21st, but we decided that on the 20th we could take 

 a simple automobile trip into the interior, just to see what the country 

 was like; and since we had previously failed to reach our destina- 

 tion, when we started for Carleton and Kemptville, that direction 

 seemed the natural one to take. Our route lay up the Tusket valley 

 and, afte* a few stops, we succeeded in getting above Tusket Falls, 

 when some one thought he saw an interesting plant on a wooded 

 slope above Tusket (or Vaughan) Lake. The shore of the lake was
