eastward ovor this region. Each of these stages is represented by its 
strife and stoss sides of hills, and by its boulder-clay or till deposits. 
The basins of the long and narrow lakes Memphremagog, St. Francis, 
Megantic, and others, are believed to be preglacial river valleys which 
became obstructed by theepeirogenic movements of the Quaternary era. 
Since the Champlain epoch, the St. Louis basin has been greatly up- 
lifted, to a maximum extent, so far as it is indicated by ancient shore 
lines, of 700 feet, or perhaps 875 feet, in the vicinity of Arthabasca, 
about 70 miles southwest of the city of Quebec. Chalmers there ob- 
served three shore lines, the highest at 875 to 885 feet above the sea, the 
second at 700 to 720 feet, and the third at 600 to 625 feet. Investigation 
by a detailed survey, however, with leveling, will be requisite for deter- 
mination of the question whether the upper shore may represent a fresh- 
water glacial lake, held by the barrier of the waning ice-sheet, which 
finally seems to have ceased its lalockade of the St. Lawrence valley in 
the vicinity of Quebec city. Then a glacial lake on its southwest side, 
which has been named lake St. Lawrence, outflowing southward into 
the Hudson river, fell to the sea level of that time, which is doubtless 
represented at Arthabasca by the lower shores, as it is known at Mon- 
treal by marine fossiliferous beds up to 560 feet above the sea on Mount 
Royal. 
The year's appropriations for this survey were $103,107.9.3, of which a 
ninth part was used in printing and lithography. During the year 31,- 
595 people visited the survey museum. It is urgently requested that 
the Dominion Government shall provide, at the earliest practicable date, 
a larger and fireproof building for the extensive and very valuable col- 
lections of the survey, which have been accumulating through more 
than half a century. A general index of the reports of the survey is 
being prepared for publication, which will include about 32,000 refer-

The Water Resources of lliinoi.s. By Frank Levekett. 155 pages, 
6 plates, and 9 figures in the text; Washington, 1896. (Extract from 
the Seventeenth Annual Report of the U. S. Geological Survey, for 1895- 
96.) This very elaborate report on the hydrogiaphy, water power, wa- 
ter supplies for cities and villages, and artesian wells, throughout the 
state of Illinois, presents also good descriptions of the surface features 
of the state, with a contoured map; of its bed rocks, with a geological 
map and sections; and of the glacial drift, which Mr. Leverett has very 
fully studied, with a map showing the moraines, till plains, loess, sand 
areas, valley drift and alluvium, and the former extension of Lake Mich- 
igan. The early till, mainly loess covered, occupies the western and 
southern two-thirds of the state, excepting a small driftless tract in the 
northwest corner (a part of the great Wisconsin driftless aiea) and a 
width of about .35 miles at the south, in the angle of the Mississippi and 
Ohio rivers, which lies outside the extreme limit of glaciation. The 
outer one of about a dozen marginal moraines, belonging to the later 
Wisconsin stage of glaciation, extends from near Terre Haute, Ind.,
