ANNOUNCEMENT! 
I will have no class in Cryptogamic Botany in Cambridge this summer. It 
is my plan to collect both Cryptogams and Phaenogams during July to Septem- 
ber in the Southern Alleghanies and on the Gulf Coast, making as full sets as 
possible and giving special attention to plants of economic interest, as Fungi, 
Grasses, etc. Some photographs of forest trees and other botanical objects may 
be made. I shall be pleased to correspond with persons interested.
