 the Eopes Mansion, 318 Essex Street, Salem, 

 Mass., by Professor M. L. Fernald, of Har- 

 vard IJniversity, on Thursday afternoons, at 

 4.15 o'clock, the subject being The Geo- 

 graphic Origin of the Flora of IN'ortheastern 

 America. The lectures are: 



January 15. The maritime flora: the flowering 

 plants of sea-margin salt marsh tidal estuaries and 

 strands. 



January 22. The coastal plain flora: the plants 

 of sand hills ; of Cape Cod; of eastern New- 

 foundland. 



Januaxy 29. The deoiduous forests: the Alle- 

 ghenian flora and its history. 



February 5. The Canadian forests: simHaritiea 

 and variations of circumpolar forest plants.

 trasting ranges of the floras of the granitic, lime- 

 stone and serpentine mountains of northern New 

 England, Quebec and Newfoundland. 



February 19. The cosmopolitan flora of the 

 future. 



The objects of the course are to present in 

 brief outline the more striking features in 

 the history of the floras of the northern 

 hemisphere — their antiquity, probable migra- 

 tions and wholesale extinctions in geological 

 time; and to make clear why, unless the more 

 sensitive and easily exterminated of our wild 

 flowers are intelligently safeguarded, they are 

 doomed to early extinction.
