with Sticta pubnonacea, and Cetraria glauca, enhancing ma- 

 terially the novelty of their appearance. Here also I found 

 a most troublesome kind of Aralia, the A. erinacea^ Hook, in 

 great abundance ; also Menziesiaferruginea, and a large species 

 ofSpircea, allied to S. Arimcus ; two or three different Uvularice; 

 a species oi Dracana^ bearing only one berry of a blue colour; 

 Pyrola umhellata, a very singular and new kind of umbelli- 

 ferous plant; Lycopodium Selago, var., Hypnum rohustiim^ 

 (Hooker;) H. vagans, tenax^ and loreum ; Dicranum hetero- 

 mallum^ and D. crispum ; Polytrichum alpinum^ urnigerumy and 

 undulatum, &c. The " Grande Cote" is of very steep and 

 difficult descent for two or three miles. Upon reaching the 

 base, we came upon Portage River, which has its rise in the 

 lake called the Committee's Punch Bowl, and which, running 

 through a small and narrow valley, perhaps 20 miles long, 

 finally falls into the Columbia River. The stream is very 

 winding, and it is necessary to cross it in many places, which, 

 at this season of the year, was a very unpleasant operation, 

 the water being often as high as a man's middle. The track 

 leaves the river in two places, where the valley is quite filled 

 with the current, or intercepted with rocks, and traverses the 

 points of two woods, in which I observed Pothos fcetida^ 

 which had not occurred since leaving New York, and, for 

 the first time, Mahonia pinnata, and a shrub resembling Box- 

 wood ; two or three species of Vaccinium unknown to me, and 

 growing two or three feet high, with large but not very well 

 flavoured fruit; a species of Noli-me-tangere ; Circcea alpina; 

 Lycopodium Selago ; Aspidium Lonchitis, acideatum, and 

 Phcegopteris ; on rocks opposite the first wooded point, were 

 Hypnum necheroides^ Bryum hornum, Weissia acutely (likewise 

 found on the Height of Land,) Bartramia Halleriana, Di- 

 cranum pellucidum ; and on stones in the river, that most 

 curious moss, Scouleria aquatica (of Hooker, in No. I. of the 

 present work, t. 19,) while the "battures," or gravelly banks, 

 left bare by the receding of the streams, were covered with 

 Dicranum julaceum, D. pellucidum, &c. We reached the 

 Boat Encampment on the Columbia, the 17th of October. 

 On the following day, the bl-igade pursued their voyage, and
