experience of the writer in finding an exotic tree naturalized in a 

 spot where it could by no ordinary possibility have been expected. 

 On June 19, 191 9, while collecting in the Calapooia Mountains 

 along Smith River, near the northern boundary of Douglas 

 County, Oregon, in a very remote and thinly-settled district 

 about twenty miles to the west of the Southern Pacific Railroad, 

 a tree was observed in a dense thicket of alders and Douglas firs 

 near the roadside that attracted instant attention. No dwelling 

 or other evidence of civilization was anywhere in sight, and the 

 "forest primeval" had apparently never been disturbed. The 

 tree stood about 40 feet in height, and was some six inches in 

 diameter above the base. At the time it was in full flower, and 

 was plainly a linden — a group not represented in the indigenous 

 flora of Oregon, although occasionally found among the shade- 

 trees in the larger towns. Closer examination of the flowers 

 showed that it was typical Tilia europaea L. — a tree as little to 

 be expected in the mountain-forest as a fan-palm. The mystery 

 was complete; but it was somewhat dispelled when, on arriving 

 at the little post-ofUce of Gunter, a few hundred yards further 

 on, the stalwart mountaineer who acted as postmaster informed 

 us that some thirty years before an Englishman had taken up a 

 homestead near the spot and engaged in bee-culture— a venture 

 that ended in speedy failure; and the linden was probably a 

 relic of his undertaking, this tree being a favorite with English 

 apiarists. The forest had speedily resumed its sway, and no 

 trace even of a clearing remained ; but the linden had grown to a 

 vigorous maturity, and will doubtless live to puzzle the next 

 collector who may penetrate to this remote and little-known 

 district.
