" sacacommis " used for this plant by " Engages," that it is not 

 clear who "Engages" were; but an engage was any hired man of 

 a fur trading company ; the word means precisely the same as em- 

 ploye or employee. Mr. Meehan states that " Professor Knowlton 

 in the notes to Coues' edition of the travels, suggests the name 

 Arctostaphylos pungens for this." But I cannot find A. pungensin 

 my book. Sacacommis is given in four places, p. 139, p. 674, p. 

 729, p. 827, in each instance correctly identified as the bear-berry, 

 A. ura-ursi. This is one of the few botanical identifications that I 

 made myself, as I happened to know the plant very well. 



Arbutus menziesi Pursh, Fl. 282. 



November 1, 1805. Cascades of the Columbia, a little above 

 head of tide-water. 



Gaultheria shallon Pursh, Fl. 283. 



June 20, 1806. " On the coast of the Pacific Ocean," as given, is 

 impossible. At that date L. &. C. were on the Lo Lo Trail in north- 

 ern Idaho. I suppose this date to be a misprint for some day in 

 January, 1806, when L. & C. were at Fort Clatsop, and repeatedly 

 mention the salal, shallun or shellwell with particularity ; see my 

 edition, p. 731, p. 739, p. 791, p. 798, p. 825. The form of the 

 name shallum, adduced by Mr. Meehan, does not occur in my 

 work. 



Vaccinium myrtillus L. ( V. myrtilloides L. in Mr. Median's footnote.) 



June 20, 1806. " Fort Clatsop," as given, is impossible ; see 

 under Gaultheria shallon. 



Vaccinium ovatum Pursh, Fl. 290. 



June 27, 1806. " Fort Clatsop," as given, is impossible ; see 

 under Gaultheria shallon. 



While on the question of Vaccinium, I should much like to know 

 what botanists can make of the " cranberry of the low and viny 

 kind" mentioned by L. and C. in the Fort Clatsop list of plants, 

 No. 11, p. 826 of my edition, and considered by Mr. Knowlton to 

 be V. macrocarpon , ibid. 



Dodecatheon meadia L. 



April 16, 1806. Rock Fort Camp, on the Columbia. In his 

 footnote Mr. Meehan says : " There might have been a specimen 

 collected on the march up the Missouri in 1804, as in the Journal 

 under date April 17th, it is noted that ' violets, doves foot and cow-
