Folio No. 83 U. S. Geol. Survey, Wash- 
ington, D. C., 1902; pp. 19; maps 13; 
figs. 1-12 in text; figs. 13-24 on separ- 
ate sheets 1 and 2. 
This folio is of special interest to 
those who reside on Staten Island 
and is indispensable for anyone 
who may desire a knowledge of the 
geology, topography or physiogra- 
phy of this vicinity. In the text there 
are chapters on the ‘‘General Geogra- 
phy of the District,’’ by R.E.Dodgeand 
Bailey Willis; ‘‘Geology of the Dis- 
trict,’’ by Bailey Willis, F. J. H. Mer- 
rill, N. H. Darton, Arthur Hollick, 
and R. D. Salisbury; ‘‘ Physiographic 
Features of the District,’’ by Bailey 
Willis and R. E. Dodge, and ‘‘ Water 
Supply of New York City,’’ by H. A; 
Pressey. The Staten Island serpen- 
tines are discussed under igneous rocks, 
on p. 5; the Triassic shale and trap, 
rock receive brief mention in connec- 
tion with the general account of the 
Newark Group in the district ; the Cre- - 
taceous clays and kaolins of the Island 
are made the subject of a special sub- 
chapter on pp. 10, 11; the Tertiary de- 
posits, represented by the yellow gra- . 
vel on Todt Hill and in the vicinity of 
Kreiecherville, are mentioned on p. 11, 
and the terminal moraine is described 
on p. 13.—Fig. 1 is a small map of the 
whole area included in the description 
and larger maps, showing the drain- 
age areas and sub-marine contours ; 
Fig. 12 is a sketch map which shows 
the direction of glaciation and the lim- 
its of the terminal moraine, with its 
furthest southern extension on Staten 
Island, and fig. 22 is a view of the 
morainal hills in the vicinity of Gras- 
mere. 
The four quadrangles into which the 
district is divided are each represented 
by three maps,—one topographic, one 
representing the surface geology, and
