of the order of presentation of the various papers which have been 
separately printed by the Society aud already reviewed in this and 
preceding numbers of the Geologist, six short papers are here printed 
in abstract or fully, as follows: On the occurrence of Megitlonyx jeffersoni in 
central Ohio, by Edward Orton ; On the familj'- Orthidit of the Brachio- 
poda, by .James Hall ; On a jointed earth auger for geological explor- 
ation in soft deposits, by N. H. Darton ; On the occurrenceof diamonds 
in Wisconsin, and on the occurrence of fire opal in a basalt in 
Washington state, by George Frederick Kunz ; and A fallen forest and 
peat layer underlying aqueous deposits in Delaware, by Hilborne T. 
Cresson. The first annual report of the committee on photographs 
gives the titles, with descriptive notes, of 293 photographs received 
by the Society in 1890, of which 21 were donated by Prof. ,J. F. 
Kemp of Ithaca, N. Y.; 2G9 by the U. S. Geol. Survey, through the 
director, major J. W. Powell ; and 3 b}' Prof. W. B. Dvvight of Pough-

This volume is a valuable one for the manganese industry in Arkansas, 
and secondarily for all who make use of manganese. It gives an account 
of the early and modern uses of manganese, and brings out vividly the 
remarkable recent increase of its mining and manufacture (in spiegelei- " 
sen and ferro-manganese) in the United States. In 1875 the net tons 
produced were 7,832, in 1885 31,671, and in 1890 149,959 tons. T.he 
methods of use of manganese in the arts, including its alloy with iron 
in the Bessemer and Hadfield processes of steel-making are fully de- 
scribed. Small amounts of manganese ore were mined in the United 
States (Tennessee) as early as 1837, but at the present time Virginia, 
Georgia and Arkansas produce over nine-tenths of the total output of 
North America. "The United States is the next largest producer of 
manganese ore in the world, being second only to the Caucasus region 
of Russia." "England is the largest consumer of manganese in the 
world, using not only its own production, but also 74,906 tons from out- 
side sources. The United States is not only the second producer but 
the second largest consumer, using its own production as well as that of 
Cuba, and most of that of Canada." 
All the various ores aud minerals of manganese, together with their 
places and manner of occurrence, are described, embracing also chemi- 
cal analyses. 
In Arkansas there are two manganese regions, one in the northeastern 
part of the state, known as the Batesville region, of which a detailed 
geological map is given, and the other in the southwestern part extend- 
ing from Pulaski county through Polk county to the Indian Territory
