PERSONAL AND SCIENTIFIC NEWS. 
Torpocgrarnic Map or tHE Unirep Stratres.—Mr. Henry Gan- 
nett, Chief of the Topographic work of the United States Survey, 
is the author of an elegant suite of maps of the United States re- 
cently printed by the survey. Last year he issued a limited edi- 
tion of a large map of the series in nine sheets, which recently 
have been reprinted in a reduced scale of 50x20 inches upon a 
single sheet. 
The map is intended primarily to show the hypsometric and 
drainage features of our country, with a minimum of political 
features. only sufficient to enable the natural features to be 
located. The altitudes are shown by contour lines printed in 
brown, the streams in blue and _ political features in black.  Va- 
rious editions are issued showing either one, two or all these 
features, and are artistically and beautifully printed. 
These maps are an invaluable addition to the cartography of 
our country, not only for their educational value, but as appro- 
priate bases for the platting of physiographic and geologic data of 
every kind, and Mr. Gannett has done a_ service to science by 
their preparation. 
Pror, H. 8. Witttams, professor of geology at Cornell Uni- 
versity has accepted the chair of geology at Yale University. 
Pror. JAMES EK. Topp, or Tapor, Lowa, has been elected pro- 
fessor of geology and mineralogy at the University of South Da- 
kota, Vermillion. 
Mr. Rosert ETHERIDGE, WELL KNOWN by his paleontological 
labors during many years of active work on the geological survey 
of Great Britain, has retired with well-earned honors, and his 
place as assistant keeper of the geological department of the 
British Museum has been filled by the appointment of Mr. A. 
Smith Woodward, author of the catalogue of fossil fishes in the 
British Museum. Mr. Woodward's name is already well known 
among paleontologists in America, as he visited this country 
about two years ago, and remained for several months. 
A GEOLOGICAL SURVEY FoR LowA has been provided for by a bill 
recently passed by the State Legislature. For the support of the 
survey for the next biennal period the bill appropriates twenty 
thousand dollars. The Geological Board will consist of the Goy- 
ernor, the State Auditor, the President of the University, the 
President of the Agricultural College, and the President of the 
Towa Academy of Science. 
A coursE oF University Extension Lectures on World 
Making has been given at Davenport, Des Moines and Iowa City, 
by professors from the State University of Iowa. The success 
attending these lectures shows that the intelligent public may 
easily become deeply interested in geological problems.
