Dear Or • Kennedy , 



* e are using for arreting our herbarium of the mos- 

 ses of the world, the outlines of the genera as given by hngler and 

 Prantl, but as this is st ill very incomplete, I have numbered them 

 according to ".aegers 'dumbratio, the system n which the »ew mosses 

 are arranged. This has en?.b 1 ed me so far to put my Hands readily on 

 any genus of exotic mosses in the collections. - 



For the Systematic museums, I am arranging a set of specimens a c coding 

 yto the Angler and r rantl system, but am notat all sati sfied with the 

 meagerness whith vhich they hr ve treated + he pleurocapppus mosses. liow- 

 ever, I fallow their sequence for my p ublished lists of mosses of N. 

 ■America though I should like to make several modifications to agree 

 with Limprichts Laubmoose , which I think is mushmore satisfactory 

 than 3 rai thv. ai tes groupings, not only becuase they cover a alrger flora 

 but becuase they are less erratic and less Lindbergi an . 

 Thank you for your very kind invitation to T'iss Small, she is doing 

 her best to get her lists in good shape -nd order, and will stop off 

 at f'rovidence on her way home and do some bibliographical work rith 

 Msls s 9ay before she calls an yru. 3y that time she will be r eady to 

 check off quickly any additions that you may have for her. 



ith kin '.est regards believe me yours sincerely,
