WEST VIRGINIA GEOLOGICAL SUR\'EY 3 



Virginia counties, but his carefully and explicitly kept Journal 

 does not bear out such a conclusion. He did however collect 

 at Harpers Ferry, Charlestown and Summit Point, in Jeffer- 

 son County, and at Wheeling, Buffalo Point, and the mouth of 

 the Little Kanawha River, on his journey to Kentucky and 

 Illinois in 1793. His collections are in the Herbarium of the 

 Museum of Paris. 



(2) Matthias Kjn, a German nurseryman and collector, took up his 



residence in Philadelphia and from there made many extensive 

 excursions for the purpose of collecting living plants and seeds 

 for horticultural purposes. During these trips he also pre- 

 served plants for herbarium material. About the year ISOO he 

 collected extensively from Cumberland, Md., through the Ty- 

 garts River Valley in Randolph County. His exact localities 

 are in doubt as his labels are eccentrically written in "Pennsyl- 

 vania Dutch." The prime set of his collections of dried plants 

 is in the Royal Botanical Garden, Berlin. 



(3) Frederick Pursh, a noted German Botanist (born in Russia) es- 



tablished himself in Philadelphia in 1799. From there he made 

 many important botanical explorations. His most interesting 

 collections were made in the vicinity of Harpers Ferry, Jeffer- 

 son County; and in Greenbrier and Monroe Counties in the 

 neighborhood of White Sulphur and Sweet Springs in 1S05. 

 His prime collection is in the Herbarium of the Royal Botani- 

 cal Gardens at Kew, London. 



(4) (CoNSTANTiNE Samuel) Rafinesque (Schmaltz), the eccentric 



Franco-German naturalist (Born in Turkey), immigrated to 

 Philadelphia in 1802. In 1818, on his way to Kentucky, he col- 

 lected plants at Wheeling, Williamstown and Point Pleasant : 

 and on his return walked from Wheeling to Kenilworth through 

 Ohio, Brooke and Hancock Counties, collecting throughout the 

 route. In 1819 he collected afoot along the Potomac River 

 from Harpers Ferry to Cumberland, Md., through Jefferson, 

 Berkeley, Morgan and Hampshire Counties. In 1825 he again 

 collected in Ohio County from Valley Grove to Wheeling ; and 

 later, starting from Cumberland, he followed the South Branch 

 of the Potomac from its mouth through Hampshire, Hardy, 

 and Pendleton Counties to the South Fork Mountains, where 

 he "collected many fine plants." From here he crossed the 

 county and the mountains to Virginia. In 1832 he again col- 

 lected in Jefferson County in the neighborhood of Harpers 

 Ferry. While his collections were undoubtedly large, and very 

 valuable, their numerical strength is unknown as -his private 

 herbarium has never been found. Some of his duplicates are 

 in the herbaria of the University of Pennsylvania and the 

 Philadelphia Academy of Sciences. 



(4a) Dr. William E. A. Aikin of Baltimore, Maryland, collected in 

 the neighborhood of Harpers Ferry, Jefferson County, about the 

 year 1833. The extent and disposition of his collections is at 

 present unknown. I have seen but one specimen of his, that in 

 Dr. Torrey's herbarium, New York Botanical Garden.

John Constable, on their collecting trip to the mountains of
