represented in the Three Forks limestone. A varied but wholly Lower 
Carboniferous fauna has been obtained from the Madison limestone. 
In chapter thirteen Mr. Stanton describes the Mesozoic fossils. 
These were obtained from the Gallatin range, near Electric Peak, 
Teton range, in the vicinity of Wildcat Peak and Huckleberry Moun- 
tain, and from the Cretaceous ridgesin the southern end of the park and 
Yellowstone Forest Reserve. There are seventy-eight invertebrates, 
one of which is supposed to be of Triassic age, forty-six are Jurassic, 
and thirty-two are Cretaceous. ‘The fossils are mainly from the Ellis 
division of the Jurassic and the Colorado of the Cretaceous. 
The last chapter, by Mr. Knowlton, on the fossil flora, is along one, 
covering 233 pages, besides 45 plates of illustrations. The Mesozoic 
flora is confined to the Laramie sandstones of the Cretaceous, and is 
found on Mt. Everts, near Mammoth Hot Springs, and at the base of 
Pinyon Peak, near the head of Wolverine Creek. The Tertiary flora is 
quite varied, and full of biological interest. On comparing it with 
the present it signifies great climatic changes since the Miocene. It is 
found in numerous localities associated with the breccias and silts of 
the igneous rocks, where the muds and silts furnished a soil favorable 
to plant growth. The Tertiary fossil flora embraces about 150 forms 
in thirty-three orders. The interesting fossil forest trees of Specimen 
Ridge are illustrated with photographs of the trees in the field and 
enlarged microscopic sections showing the cellular structure. 
The petrographical and paleontological features of the Yellowstone 
National Park are certainly described in great detail, and the mono- 
graph will no doubt prove to be a valuable handbook to scientists, 
especially to those visiting the region.

Report on the Geology and Natural Resources of the Area included by 
the Nipissing and Temiscaming Map Sheets, comprising portions 
of the district of Nipissing, Ontario, and of the county of Pontiac, 
Quebec. By ALFRED ERNEsT Bartow. Geological Survey

This report, accompanied by two well-executed maps on a scale of 
four miles to the inch, and covering an area 6912 square miles of the 
northern Protaxis of the Dominion of Canada, is a valuable addition 
to the literature of the pre-Cambrian of North America and isa further
