Mycologia 



Schweinitz continued his study of the flora of North Carolina 

 until his removal to Bethlehem, Pa., late in 1821, probably about 

 November 20. 4 At Bethlehem, Schweinitz came into closer touch 

 with several American students of botany, a circumstance which 

 he evidently greatly appreciated. In the introduction to the Syn- 

 opsis Fungornm in American Boreali (13 p. 141) he says " Sub 

 finem autem anni jam dicti [1821], in paterna mea domicilia 

 Bethlehem, Northampton County, Pennsylvaniae denum redux. . . . 



Botanophili Americani plurimi jam mihi propinquiores, quam 

 degenti olim apud occidentales Carolinenses, penitus toto ab orbe 

 divisos, summa benevolentia et summo studio, quos ipsi inven- 

 erant aut quos illis aliunde missi sunt communicaverunt, prae 

 ceteris amicissimus doctissimusque D. John Torrey, Novebora- 

 censis Universitatis Professor." 



Torrey was throughout this period Schweinitz's most frequent 

 and valued American botanical correspondent. Torrey at times 

 sent him fungi for identification (15, p. 8), and also loaned him 

 books 5 which happened to be inaccessible, among others Fries's 

 Systema Mycologicum, Pt. 1. At one time Torrey and Schwei- 

 nitz evidently had under consideration the publication of a joint 

 Cryptogamic Flora. 6 



Schweinitz resided at Bethlehem from 182 1 until his death, 

 February 8, 1834, and here he completed, in addition to several 

 papers on higher plants, his most important scientific work, the 

 Synopsis Fungorum in America Boreali (13). During this 

 period Schweinitz twice made journeys on church affairs. In 

 the summer of 183 1 he went to Hope, Indiana, to organize a 

 church there. Somewhat earlier he went to Europe to attend a 

 meeting of his denomination at Herrnhut. The date of this 

 journey is given by Johnson and Miss Lehman as 1824, but 

 letters to Schweinitz from Hooker and Torrey indicate that it 

 was made in 1825. 7 



During the latter years of his life Schweinitz regularly used 

 the prefix, de, in his signature, though he never seems to have 



* Letter to Torrey dated October 29, 1821. 



5 Letter to Torrey dated Bethlehem, May 15, 1822. 



0 Letter to Torrey dated January 16, 1825. 



7 Under date of March 30, 1825, Torrey mentions an effort to meet 

 Schweinitz in* New York on the latter's way to Europe.
