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, 1843, crossed a high spur 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 junction with the Spokane. 
During the season of 1844 Geyer made excursions northward to Old 
Fort Colville on the Columbia, southeastward up the Spokane River 
and into the mountains about Lake Coeur 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 Walla Walla 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- 
markably good. A nearly complete set of his plants is in the Gray 
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 Herbarium. Most of them are labeled 
* Clearwater, Oregon,” but inasmuch as a number of them have not 
since been found near Lapwai it is not improbable that they were col- 
lected elsewhere. 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 he made collections on Vancouver Island and on the smaller 
islands and the mainland near the forty-ninth parallel. In 1859 the 
western slopes of the Cascades near the boundary were explored. In 
1860 the surveyors went up the Columbia, dividing at The Dalles 
into two parties. One party, which Lyall accompanied, traveled in 
a northerly direction, past Fort Simcoe, across the Naches and other
