were later deposited; in Finland these consist of quartzites, schists, 
dolomites, and beds of anthracitic carbon; in age they are probably 
equivalent to our Upper Huronian. Into these, after a period of folding, 
the rapakivi granites were intruded; and, at a still later date, a variety 
of other intrusives. Then came a great period of denudation and very 
complete peneplanation, before the deposition of the Jotnian sandstones. 
These sandstones are subaerial deposits, little metamorphosed, and 
considered the equivalent of our Keweenawan. After another period 
of complete peneplanation the Cambrian was laid down. Unlike most 
of the Cambrian of America, the Swedish Cambrian has a weathered 
breccia as its basal facies. is Kear Gta Os 
A Geographical Report on the Franz Josef Glacier. By JAMES 
MAcKINTOSH BELL, with Topographical Maps and Data by 
REGINALD PALMER CREVILLE, and Botanical Notes by 
LEONARD COCKAYNE. Department of Mines, New Zealand 
Geological Survey. Wellington, New Zealand, 1910. Pp. 14; 
maps 3; photographs 6. 
The Report is a very readable description of the Franz Josef Glacier 
system, which is of the valley type, and descends to an altitude of only 
692 feet above sea-level, although it lies in latitude below 44°. The 
topographic maps are not contour maps. The Botanical Notes give a 
list of the plants found between the glacier and the coast-line.

A Report on the Geological and Mineral Resources of the Arbuckle 
Mountains, Oklahoma. By CHESTER ALBERT REEDS, PH.D. 
Oklahoma Geological Survey. Bulletin No. 3. Norman, 
Okla:, December, 1910. Pp. 69; plates 24; figs. ro. 
The Arbuckle Mountains are a moderately dissected plateau ranging 
in elevation from 1,300 feet in the north and west to 750 feet in the south- 
east portion. The mountains came into existence in Pennsylvanian 
times, and since then have been subjected to elevation at three different 
times, as attested by records of the Cretaceous base level and the inter- 
rupted Miocene and Pleistocene erosion cycles. 
The region consists of pre-Cambrian granite and porphyry upon 
which rest unconformably approximately 10,000 feet of Paleozoic 
sediments, ranging in age from Middle Cambrian to Pennsylvanian, and
