Petrographical Notes on So/ne Rocks from the Fiji Islands. By 
Arthur S. Eakle. (Proc. Amer. Acad. Arts and Sci., vol. 34, no. 
21, pp. 581-595, May, 1899.) 
The rocks here described were collected by Mr. Alexander Agassiz 
during the winter of 1897-98. The Fiji group consists of two larger 
islands — Viti Levu or Great Fiji, and Vanua Levu — and a large num- 
ber of smaller islands. The first mentioned and largest of the islands 
differs from the others, as far as known, in having plutonic rocks, as 
granites, syenytes, diorytes and gabbros, while the other islands, 
aside from their coral rocks, show surface igneous rocks. A speci- 
men of dioritic granite is described from this largest island, Viti Levu, 
and the other specimens are andesytes (of several varieties) and ba- 
salts. In all some twenty-five islands are represented by the speci- 
mens collected, and a description of the characters of each specimen 
is given. u. s. o. 
Mineral Resources of Kansas, i8qS. By Erasmus Haworth. 
(The University Geological Survey of Kansas, Annual Bulletin on Min- 
eral Resources; 127 pp., 21 pis.; Lawrence, July, 1899.) 
The total mineral products from Kansas for 1898 amount to nearly 
$27,000,000. Of this the non-metallic products, coal being by far the 
most important, give a total of about $6,000,000. The only metallic 
products are lead and zinc, over $4,000,000 worth of these two metals 
being produced. The smelting products amount to over $16,000,000. 
Twenty-four tables show the amounts of the different substances 
produced, both by counties and by districts, and in some cases by 
geological formations. A number of reports of gold and silver in 
Kansas have been made, but these are not substantiated. As a final 
report on lead and zinc will be completed during the next fiscal year, 
the information presented concerning these subjects is briefer than 
would otherwise be the case. Nearly ninety-five per cent, of the coal 
conies from the Lower Coal Measures, and the balance, except about 
500 tons from the Cretaceous, is from the Upper Coal Measures. In 
certain years the amount of Cretaceous coal produced has been greater, 
as in 1894, when over 17,000 tons were produced. The few pages 
devoted to the geology of the oil and gas fields are quite acceptable, 
as information concerning this subject in Kansas is difficult to obtain. 
Under the heading of salt Mr. M. Z. Kirk contributes two papers, one 
on "Kansas Salt" and one on "Technology of Salt," and Dr. Haworth 
describes the "Geology of Kansas Salts." including the records of a 
number of salt wells. u. s. G.
