LITERATURE.

ogist for the Year 1903. Henry B. Kummel. Pages xxxvi, 132; 
with 14 plates. Trenton, N. J., 1904. 
Besides the administrative report, noting the work of the last year, 
this volume contains the following five papers: i. Report on a pro- 
posed Tide Waterway/ between Bay Head and Manasquan Inlet, by C. 
C. Vermeule; 2. The Floods of October, 1903, — Passaic Floods and

The St. Louis Exposition commissioners for this state appropriated 
$5,000 for a geological exhibit of the state's resources, under the di- 
rection of the state geologist and S. H. Hamilton. After the close of 
the Exposition, this collection of specimens, photographs, maps, etc., 
will be placed in the State Museum. 
It is announced that Prof. R. D. Salisbury during the present year 
will begin the preparation of a monograph, for this Survey, on the 
surface geology of southern New Jersey, supplementing his previous 
Volume V of the series of Final Reports, which treats of the Glacial 
Geology, limited to the northern part of the state. This work will 
be welcomed as supph'ing correlation of the stages of the Glacial pe- 
riod with the stages of the Lafayette and Columbia periods, which 
have been so well studied along the southern coastal plain frmii Xew 
Jersey to the gulf of Mexico. 
During 1903 the mining of iron ore in Xew Jersey yielded 289,323 
tons; and of zinc ore, 279,419 tons. Iron mining is only a half or third 
of its maxima in former years ; but the zinc mining has gradually ad- 
vanced to four or five times its amount as it was six to twelve years 
ago. w. V.
