Prof. J. Paul Goode, of the State Normal Scliool at Moore- 
head, Minn., delivered two coursepof lectures on physiog-raphy 
at tile summer school of the University of Minnesota. 
WiLLiAii Williams Matheu. A sketch, with portrait, of 
this geologist is given in Appletons'' Popular Science 3Io)ithli/ 
for August. Mr. Mather is known especially for his fine work 
on the Geological Survey of New York during its early years, 
and also as the first state geologist of Ohio. 
Pkof. G. FuEBEPacK Wright, in the preface of the new 
fourth edition of "The Ice Age in North America," dated 
last June, gives in seventeen pages an enumeration of the 
principal contributions to the literature of the glacial geology 
of this continent during the past five j^ears, with occasional 
notes of comment and criticism. 
The California State Mining Bureau has recently issued 
(Bulletin No. 8, April, 1896) a statistical table showing by 
counties the mineral productions of the state for the year 
1895. The total product amounted to .|22,841,661.29, or an 
increase of more than two and a half millions over 1894. The 
production of precious metals for 1895 was $15,934,107.39, of 
which almost $600,000 was silver and the balance gold. The 
table was compiled by Charles G. Yale, statistician, from 
direct returns from the producers. 
The four-tusked Mastodon. On page 325 of this magazine 
for May, 1895, in a notice of the Mastodons recently set up 
at Cincinnati, the remark is made that the Mastodon with two 
tusks in the lower Jaw has been hitherto limited to the Old 
World. Referring to this passage, professor B. K. Emerson 
writes. "The museum of Amherst College contains a specimen 
of Jf. americnnvs with both the tusks preserved in the lower 
jaw. They are ten inches long and two in diameter." The 
same museum also contains the two lower tusks of J/, shep- 
ardi from California, described by Dr. Leidy. 
Prof. J. D. Whitney, of Cambridge, Mass., died at New 
London, N. H., Aug. 19, at 77 years of age. Prof. Whitney 
was graduated from Yale in 1839, and in 1840 he made an 
extended survey of New Hampshire. In 1847 he made a geo- 
logical exploration of the lake Superior region, followed hy a 
survey of the mining regions of all the states east of the Mis- 
sissippi river. In 1855 he was appointed state chemist of 
Iowa and professor of the Iowa State University. In 1860 he 
was appointed state geologist of California and five years later 
he was made professor of geology of Harvard university. In 
1870 Yale honored him with the degree of LL.D. In a future 
issue the Geologist will contain a suitable sketch of this em- 
inent geologist.
