tion of photographs and lantern slides during the coming year, which may 
illustrate the most common and prominent topographic features of the 
State. It would, of course, be desirable to have both series in the schools, 
but when the purchase of a lantern is not possible, photographs, of course, 
may be substituted. It is hoped that such a collection of laboratory ma- 
terial may create and stimulate further interest in the subject and help 
to place it on an equal footing with the other observational sciences ob- 
served in the school system. 
Maps.—There are a number of sources from which many selections of 
useful illustrations of topographic types may be obtained. The United 
States Geological Survey has prepared a large number of topographical 
and geological sheets covering portions of the United States. It is to be 
regretted that this national organization has not published a single sheet 
covering any portion of the State of Indiana. A part of this neglected 
work is being done by the Geological Department of Indiana University. 
In addition to the series of sheets mentioned above, the National Survey 
has lately prepared a large number of folios, forming a part of the 
“Geologic Atlas of the United States.” Vhese have been made to serve 
educational purposes in partictilar, but strange as it may seem, a large 
number of the best equipped high schools of the State have failed to 
make use of the opportunities offered. The folios contain a topographic 
sheet, a second showing the areal geology, a third illustrating the geology 
in cross section, and sometimes a fourth devoted to the economic geology. 
Each folio is accompanied with an explanatory text. 
From the United States Coast and Geodetic Survey may be obtained 
a series of maps giving the minutest details of shore-line topography. For 
a list of the maps address this department at Washington, D. C. 
It is gratifying to learn that in a few of the high schools of this State 
the daily weather maps are being used with a considerable degree of suc- 
cess. These may be obtained by addressing the local forecast official, 
Cc. F. R. Wappenhans, Majestic Building, Indianapolis. 
Another source for information of meteorological interest is the United 
States Hydrographic Department, which issues each month a series of 
pilot charts of the North Atlantic and North Pacific oceans. On these 
charts are shown the storm tracks, the date of their occurrence and the 
direction of their course (from which can be determined their rate of 
movement), calms and prevailing winds, derelicts and wrecks, icebergs 
and field ice, regions of frequent fog, ete.
