As some have thought the list of lichens, on pp. 413 and 414, was intended to com- 

 prehend everything of that class of plants, I will take occasion to say that it is intended 

 to embrace only those which are peculiar to the White Mountains, but not those which 

 grow there, and elsewhere, also. The list was compiled from Prof. Tuckerman's two 

 valuable books, bearing the dates of 1872 and 1848. It is hoped that, by calling atten- 

 tion to the plants peculiar to the mountains, botanists may be induced to investigate 

 further the question of the limits between the alpine and sub-alpine districts. 



River Systems. Mr. Upham desires to correct the opening statement of Chapter 

 XI, that one sixth part of New Hampshire is covered by water. The estimate was 

 borrowed without reflection from the report of the New Hampshire Hydrographic Com- 

 mission in 1870. Pie thinks the figure should be not more than one eighteenth, instead 

 of one sixth. 



Note to page 247. I understand that the boundary between Carlisle's and the Acad- 

 emy grants has been run out the present season, in accordance with the original line 

 of forty-five degrees of north latitude. 



Average Elevation. The average elevation of the land above the ocean should have 

 been stated at twelve instead of fourteen hundred feet, on page 296.
