State Geological Surveys and Practical Geography 57 
the interrelation between the organic and inorganic parts of the 
subjectj and impressing the necessity of a strict terminology. 
While in a few text-books some or all of these ideas may be exem- 
plified, they are not given the prominence that insures an appre- 
ciation of their importance. 
b. Supplementary reports summarizing for teaching purposes 
the more extended publications would be of great aid to the 
schools. For example: In recent years several States have issued 
extensive studies on their clays and clay industries. In nearly 
every case these were prepared by specialists; they contain much 
that is purely technical, besides facts that contribute to human 
relations; the facts bearing on geography admit of correlation, 
affording in particular an opportunity to emphasize the organic. 
Some States have issued reports on one or another phase of 
physiography; others are engaged on more extensive physio- 
graphic studies. These contemplated publications may be strictly 
physiographic, embodying only the inorganic, in which case they 
will disregard half their scope for usefulness in the schools. 
Type sets of topographic sheets. The laboratory manuals 
in physiography leave no occasion for reference to this topic, so 
far as classes in that subject are concerned. It is seldom, however, 
that we find topographic sheets used with classes in elementary 
geography. These younger pupils, consequently, do not get any 
conception of the map representation of relief. For their teachers, 
for the classes, and for older students as well, it would be a great 
service if Surveys were to provide at a minimum cost mounted 
sheets illustrating types of topography; so far as is possible, the 
sheets should be selected from the State concerned. Concise, 
lucid explanations should accompany the maps. 
I am aware that teachers and school boards may secure these 
maps directly from Washington. But the sheets are not exten- 
sively used even in high schools. Their use would become more 
general if some organization of the State were to take an active 
interest in seeing that the proper sheets are selected, that these are 
made more durable by mounting, that their import is to some 
extent particularized upon, and that the subject of using such 
maps is brought directly to the attention of the parties who should 
use them.
