Queensland is nearly 1300 miles in length, from north to south, and 
r>50 miles in greatest width. It stretches from south latitude 29° to 10° 
and possesses, except in the southern portion, a truly tropical climate. 
The Mineralogii of Pennsylvania. Part I. By John Eyerman. (To 
be used as a supplement in connection with Dr. F. A. Genth's "Pre- 
liminary report on the mineralogy of Pennsylvania"). 8vo. pp. 48, 
Easton, Pa. The author of this pamphlet brings together such dis- 
coveries of new minerals or new localities of minerals as have been 
brought to notice since the publication of Genth's "preliminary re- 
port," fourteen years ago, rendering a real and important service to 
the mineralogy of Pennsylvania. The new facts are partly his own, 
and partly are derived from scientific journals and published proceed- 
ings of societies. In addition to names of new minerals or localities, 
various descriptive notes and chemical analyses are given. 
Woods mine, in Lancaster county is reported to have produced 200,- 
000 tons of chromite, and to have netted its owners at least $5,000,000. 
It was exhausted after it had reached a depth of 800 feet. It was open- 
ed in 1834 and was abandoned in 1881. Since then the United States 
has received the most of its chrome ore from the Urals in Russia, and 
from Turkey in Asia. Mr. Eyerman gives localities and notes on 121 
difTerent mineral species. 
In a paper on the mineralogy of the French Creek mines (Trans. N. 
Y.Acad. Sci. Jan 14, 1889) Mr. Eyerman reports an interesting variety 
of orthoclase. The crystals are columnar, and, radiating from a centre, 
form a shelf-like structure. The largest crystals seen were (54 mm in 
length ; color, light green to light pink, the green varieties having a 
small percentage of manganese oxide. 
Salt; its discovery and manufacture in Kansas. By Kobeut Hay. 
(Ex. from fitli Bien. report Kan. State Board of Ag.) It is seldom 
that in a brochure so small and unpretentious, so much of value is ex- 
pressed as is contained in this review of salt in Kansas. After a short 
historic sketch of the manufacture of salt in Europe and in America, 
Prof. Hay states that it has been found, belonging to various geologic 
periods, under a great part of the surface of Kansas. The state geolo- 
gists, professors Mudge and Swallow, inferred that salt would be found 
by boring, and referred the salt marshes, that are frequent, to the effect of 
the Triassic formation. The deposits that have recently been found are at 
the base of the Triassic, and, through the usual and well-known varia- 
tion to gypsum, are probably continuous Avith the Permo-Carbonifer- 
ous below. The review contains numerous analyses, showing that the 
Kansas salt compares well with that from other parts of the United 
States. 
The "thickness of salt besides the saline shales" appears to be at 
Ellsworth 140 feet, Lyons 250 feet, Hutchinson 250 feet, Kingman 
200 feet, Anthony 75 feet. Great Bend 125 feet and Sterling 198 feet. 
All the towns named are making salt or in the early stages of erecting 
•'salt blocks."
