F. G. Plummer and M. G. Gowsell contribute an account of “ The 
Forest Conditions in the Lincoln Forest Reserve, New Mexico." 
This paper appears as Professional Paper 33 of the United States 
Geological Survey. The maps and illustrations are particularly 
interesting to the general reader. 
An interesting feature brought out by the map accompanying the 
report on “ The Forest Conditions in the Little Belt Forest Reserve, 
Montana, and the Little Belt Mountains Quadrangle,” by J. B. 
Leiberg (Professional Paper 30, United States Geological Survey), is 
the large amount of territory that has been deforested by fire. It is 
estimated that of the 500,000 acres in the reservation 111,000 acres 
have had the forests destroyed by fire. 
Bulletin 258 of the United. States Geological Survey is a second edi- 
tion of *Origin of Certain Place Names in the United States," by 
Henry Gannett. It contains all the notes of the earlier edition (Bu/- 
letin 197, United States Geological Survey) as well as some fifty-four 
additional pages. . 
FR A. Wilder, in “The Lignite of North Dakota and its Relation 
to Irrigation” (Water Supply and Irrigation Paper, 117), presents 
much interesting matter concerning this fuel. The lignite area, save 
for two or three outliers, occupies the western portion of the State. 
In this area, which is nearly half the size of Ohio, there are seams of 
lignite from an inch up to forty feet in thickness. 
Water Supply and Irrigation Paper, 114, “The Underground 
Waters of Eastern United States," presents a general summary of 
the 'ground-water conditions east of the Mississippi River. The 
waters of each State are treated, either by the State Geologist or by 
some member of the United States Geological Survey who has made 
special investigations in the area. Appended to the description of 
each State 1 is a brief bibliography of the more important papers. 
Bulletin 3, Fourth Series, Geological Survey of Ohio, is a volume 
of 391 pages and 81 Pentre by A. V. Blaininger on the “ Manufacture 
of Hydraulic Cements.” The chapters on “The Analysis and Test- 
ing of Raw Materials” and “The Burning of Portland Cements ” 
should be especially useful to a due cement manufacturers and 
cement chemists.
