Mr. Walter Deane , 



Cambridge, Mass. 



My Dear Sir, 



Being actually engaged in monographing the 

 Quebec Carices,I just thought that you have an important North- 

 eastern herbattum which must contain useful references as to 

 distribution of Carex species, and I take the liberty of in- 

 quiring whether there would be some means of securing these 

 data. 



My authority as to nomenclature for this genus is Mr. 

 Mackenzie which has examined all my specimens from Quebec. 

 The above-mentioned gentleman, as you know, has done considerable 

 work to clear up some dark points as to spe cif ic distinctions 

 and for the sake of uniformity, I would be very glad if you 

 could have your Quebec specimens revised by him. 



Please tell? me if I have sent you my book ofl "la flore 

 du Temistfouata" recently published. If not, I will be glad to 

 contribute it to your library. 



I spent last season on the Lower St. Lawrence Islands 

 especially at Anticosti,and have brought back numerous inter- 

 esting things. These northern collecting grounds are most 

 attractive. 



Thanking you for past favors, I remain, My Dear Sir, 



Yours very truly,
