Review of Recent Geological Literature. 367 
well shown that the beaches of lake Warren south of lake Erie were 
contemporaneous with the accumulation of adjacent moraines (Am. 
Jour. Sci., April, 1892); while the basin of lake Iroquois, the glacial 
expansion of lake Ontario, according to levelling by Gilbert and Spen- 
cer, has been uplifted like that of lake Agassiz, but with a greater 
northward ascent of the old Iroquois beach, amounting to five feet per 
mile for fifty miles from Rome to near Watertown,N. Y. It seems therefore 
improbable that these recent epeirogenic movements on each side failed 
to extend across the area of lake Superior. Under the assumption 
that they were thus continuous, the highest shores at Duluth and on Mt. 
Josephine seem readily referable to an ice-dammed lake in the western 
part of the Superior basin outflowing in a channel eroded across the divide 
between the Bois Brul6 and St. Croix rivers (Geol. of Minn., vol. ii,p. 
<542), from which there is an ascent of about 140 feet in a distance of 
130 miles northeast to the 607 feet shore terrace; but the 418 and 414 feet 
shores at Jackflsh bay and Sault Ste.Marie, with all found at lower ele- 
vations, would belong to the more extended stage of lake Warren when 
it outflowed to the Mississippi across the low divide at Chicago, about 
595 feet above the sea, whence the former lake level now has an ascent 
■of 421 feet in about 350 miles to the highest shore at the Sault. 
The American Meteoi-ological Journal, published now at Boston by 
•Ginn & Company, was started at Ann Arbor, by Prof . M.W. Harrington, 
who is now the chief of the Weather Bureau, at Washington, and who 
remains as a " contributing editor." The journal is a valuable one for 
all physicists who study the climatology of the country, and we can 
commend it for being ably edited and as an excellent repository of cur- 
rent discussions of the principles and progress of meteorology. 
Geologic Atlas of the United States, The following sheets have 
been issued as geological maps, dated Oct., 1892, Chattanooga, Kingston, 
and Hawley; also the Sacramento sheet,dated Jan., 1893, and the Lassen 
Peak sheet as "preliminary edition of 1892.'' Each sheet area is repre- 
sented by four sheets, one giving the topography, which is expressed by 
<;ontour lines at intervals of 100 feet, one the areal geology, one the 
economical geology, and the fourth, structure sections or other illustra- 
tions. These four sheets, which are colored according to the conven- 
tions of the survey, are accompanied by four or five other sheets or 
pages of descriptive text, and the whole are loosely embraced in a folded 
<;ase of heavy raanilia paper, on the front or title-page of which is an 
"index map" showing at a glance the position of the mapped area with 
respect to the rest of the country. 
These five sheets are the first completed product of the United States 
Geological Survey. When the whole country shall have been repre- 
sented in this style, the United States will have a geological and general 
descriptive atlas of which no American will be ashamed.
