348 APPENDIX TO PARTS I AND II. 
upon good evidence to be 16 feet higher than was formerly supposed (see Vol. I, pp. 
250-252). Referred to this datum, however, the height of Winnipiseogee lake appears 
to be 11 feet above that obtained by the survey for the Portsmouth, Great Falls & Con 
way Railroad (Vol. I, p. 265). One of these determinations of the level of the lake 
must be incorrect. Heights along Contoocook river and on streams in Antrim, with 
corrections to be made in Volume I, page 268, are stated in this volume on pages 102 
and 119; heights along Salmon Falls river, on page 150; and in Dover, on page 156. 
Mr. George L. Whitehouse, of Farmington, informs us that the height given in Volume 
I, page 264, for the summit between Alton and Farmington, refers to the highest point 
of the railroad, while the greatest depth that would have to be cut through to turn Win- 
nipiseogee lake into Cochecho river is only 28 feet, which calls for a correction on page 
129 of this volume. 
To the tables of altitudes previously published, we append a few additional observa- 
tions, principally in the mountain region:
