Providence, August 10, 1932 
Dear i'emald, 
Since your monograph of the linear-leaved 
Potamogetons arrived a few days ago 1 have been enjoying 
it, as opportunities permitted. I want to congratulate you 
on the fine piece of work, it is a great credit to the 
author as well as the photographer and printer. 
Shank you ever so much for sending me a copy (or should 
my thanks officially go to the Gray Herbarium?) 
1 notice error that you may wish to note: on page 7 €r, 
in the "Khode Island" paragraph, Smithville should read ~ 
Smithfield . as fountain Spring Br1>ok is mainly in Smithfield. 
. 'Sincerely 
hu.,. -
