Professor Edward Hitchcock in 1861, in an elaborate paper (Amer. 
Journ. Sci. (2) XXxX1, 372), gave numerous examples that he regarded 
as proving his views, which were the same as those given above. In 
the same journal (p. 440), Professor W. B. Rogers opposed the 
views advanced by Professor Hitchcock in his communication (be-— 
fore mentioned) to the Boston Society. This paper of Professor 
Rogers was given before this Society on the 17th of November, 
1860. ; 
Professor Hitchcock’s views upon this subject were more fully pre- 
sented in his Report on the Geology of Vermont (i, 28-45). The 
subject was again brought forward by his son, Professor C. H. 
Hitchcock, in his Reports on the Geology of Maine (1, 177, 11, 244, 
324), new localities. given and similar views advanced. In 1867, 
at the Burlington meeting of the Am. Assoc. Adv. Sci. (xvi, 124), 
this latter gentleman also called the attention of that Society to the 
subject. 
At the Buffalo meeting of the same Society, 1866 (xv, 83), Mr. 
B. S. Lyman, prior to this, had opposed the views of Professor C. H. 
Hitchcock regarding the Newport conglomerate. 
Professor George L. Vose read a paper, January 3d, 1868, ‘On 
the Distortion of Pebbles in Conglomerates,” etc., which was pub- 
lished in the Memoirs of this Society (1, 482-487). The locality 
especially described was the one at Rangely Lake in Maine. He ob- 
jected to the idea that the pebbles had ever been plastic, but con- 
sidered that the indentation, bending, elongation, and even a change 
into a ‘‘homogeneous crystalline mass resembling syenite,’ had 
been produced by pressure simply. 
At the Salem Meeting of the Am. Assoc. Adv. Sci., 1869, (xv, 
199-205), Mr. Wm. P. Blake called attention to some conglomerates 
and slates in Arizona and California, in which he thought similar 
contortions and elongations had taken place, and regarded mechani- 
cal force alone as the agent. 
We again revert to this Society when at the meeting of May 19th, 
1875, Professor Wm. B. Rogers brought up the old question of the 
Newport conglomerate, and opposed the view that the pebbles had 
ever been elongated by pressure, but that these forms were natural: 
shapes produced by beach action. (Proc. Bost. Nat. Hist., Soc., 
Xvi, 97-101). Inthesame volume, (p. 224-225), can also be found 
some remarks upon the conglomerate of Harvard, Mass., by Mr. L. 
S. Burbank, in which he claimed some very remarkable contortions
