The Geology of Moriah and Westport Townships, Essex County, N. 
Y. By James Furman Kemp. (Bulletin of the New York State Mu- 
seum, vol. 3, no. 14, pp. 325-355, with maps and sections: Sept.. 1895. i 
The detailed areal and structural geology of these townships, including 
part of the eastern border of the Adirondack's, and extending from 
Crown Point fifteen miles north to Split Rock mine, on the shore of 
lake Champlain. is here elaborately mapped and described. Very ex- 
tensive deposits of magnetite, attaining in one mine a thickness of 200 
to 300 feet, are found in the older gneisses. The district also has other 
vast masses of magnetite which are worthless for mining on account of 
their being titaniferous, and these '"invariably occur in dark, basic 
gabbros and in such relations as to make the inference unavoidable, that 
they are excessively ferruginous or basic portions of the original igneous 
magma." w - u - 
Geological History of the Chautauqua drape Belt. By R. S. Tarr. 
(Bulletin 109, Cornell University Agricultural Experiment Station, pp. 
91-122, with figures 48-71 in the text, including maps, sections, and 
views from photographs; Jan., 1896.) Attention is chiefly directed to 
the beaches of the glacial lake Warren, their resemblance to the present 
shore of lake Erie, and their relationship to the moraines. The princi- 
pal grape belt narrowly skirts lake Erie, reaching from the shore up- 
ward about 200 feet. Its soil was much modified by ancient lacustrine 
action, and its climate is now much influenced by the broad lake on its 
windward side. w. a. 
On Dikes of Oligocene Sandstone in the Neocomian < 'lays of the Dis 
trict of Alatyr, hi Russia. By A. P. Pavlow. (Geol. Magazine, n. s.. 
dec. 4, vol. 3, pp. 49-53, pi. 5, Feb., 1896.) The dike described is from 
12 to 14 inches in width, stands nearly vertical, and is composed of 
quartz sand mixed with glauconite grains. The country rocks, which 
are cut by the dike, are clays of lower Cretaceous age, and the dike it- 
self contains fossils of the Tertiary. The author suggests that, a fissure 
being formed in the clays, the overlying sandstone, still unconsolidated, 
simply fell in and filled the fissure. He uses the term "Neptunic dikes" 
for these dikes of sedimentary rock. D. 8. G.
