16 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



GEYER. 



Charles A. Geyer, a German botanist who had previously botan- 

 ized extensively in Illinois, and who later was attached to Nicollet's 

 expedition, traversed the continent with a party of missionaries, and 

 in November, 1S43, crossed a high spnr of the " Green " (Bitterroot) 

 Mountains from the Flathead to the Spokane or Coeur d'Alene River, 

 and passed the winter at Chamokane Mission, situated on Chamo- 

 kane Creek, about 10 miles from its jiniction with the Spokane.- 

 During- the season of 1844 Geyer made excursions northward to Old 

 Fort Colville on the Columbia, southeastward up the Spokane IJiver 

 and into the mountains about Lake Canir d'Alene, and southward to 

 the Palouse River and to Lapwai Mission, near the mouth of the 

 Clearwater. From here he explored the Craig Mountains of Idaho. 

 Journeying overland to Fort AValla AValla he descended the Colum- 

 bia, and reached Fort Vancouver November 13, 1844, whence he 

 sailed to England. 



Geyer's account of the flora of the regions explored by him is re- 

 ma rkal)ly good. A nearly complete set of his plants is in the (jrray 

 Herbarium. 



SPALDING. 



Rev. Henry Spalding was a missionary to the Nez Perce Indians 

 and founder of Lapwai Mission near the mouth of the Clearwater 

 River, Idaho. In this vicinity Spalding collected a good many 

 plants which are in the Gray Ilerbarium. Most of them are labeled 

 " Clearwater, Oregon," but inasmuch as a number of them have not 

 since been found near Lai)wai it is not improbable that they were col- 

 lected elscAvhere. Spalding traveled quite extensively in the course 

 of his labors, and doubtless gathered some of his specimens at other 

 places than Clearwater, as, indeed, some few of the labels indicate. 

 His notes on the Indian food plants are most interesting and often 

 quite detailed. According to the testimony of his son, the late H. H. 

 Spalding, the specimens were largely gathered by his mother. 



LYALL. 



Dr. David Lyall was the surgeon and botanist attached to the In- 

 ternational Boundary Survey. His work, so far as it relates to 

 Washington, was during the years 1858 to 1860, inclusive. During 

 1858 lie made collections on Vancouver Island and on the smaller 

 islands and the mainland near the forty-ninth parallel. In 1851) the 

 western slopes of the Cascades near the boundary were exi)loi-ed. In 

 18()0 the surveyors went up the Columbia, di\'iding at The Dalles 

 into two parties. One party, which Lyall acconq^anied, traveled in 

 a northerly direction, past Fort Simcoe, across the Naches and other
