Dear Mr*Collins, 
The family of the late Mr.Holden of Bridgeport,Conn.,have 
asked me to try to sell his botanical books for them;my plan is to issue 
a ms.list,to be sent to people that I think may be interested; I am fairly 
familiar with the books on algae,that make up the bulk of the lot;but there 
are others,among them a few on mosses,about which 1 know nothing. Can you 
give me an idea of a fair price for the following,and if any of them are worth 
so little as not to be worth putting in the list! 
Barnes,Artificial key to genera and species of mosses. 
E.G.Britton,Contributions to American Bryology,Nos.1,3,4 & 5. 
Austin,Musci Appalachian!,1#70. 
Evans,Hepaticae of the Harriman Expedition. 
Notes on N.A.species of Plagiochila. 
Revision of N.A.species of Frullania. 
Thailophytes of the Galapagos Islands. 
Lesquereux & James,Manual of Mosses,l£S4. 
My information you can give me on these,will be very acceptable. 
Very Truly,
