marble, iron and other useful metals, as well as the precious 
metals, mining, etc. Many good models for this work may be 
found in the reports of the tenth census. 
/ V\ Scctionizing. 
Under this division we required of our last class the following: 
1. Actual section of some bluff showing a format io7i^ a 
stratum., and a lamina. 
2. East and west section of some state. These sections were 
made in standard colors, on stiff paper, size 12x15 inches, appro- 
priately lettered, with key and proper scale. 
3. Section of the Missouri river bluffs south of Peru. This 
section was required to be made in ink and on stiff drawing paper. 
The explanations, plates and notes may be modeled after sim- 
ilar sections in standard geological reports. 
The teacher to a certain extent may modify his work to suit 
the demands and special advantages for certain lines of work. 
For example most of the time of the class may be given to 
certain parts of geology, as mineralogy, paleontology, strati- 
graphical or geographical geology. The student should be re- 
quired to keep neat, full and accurate record of all the work 
done. He may be stimulated much by allowing him to retain, 
after leaving the class, his records and drawings, including maps 
and sections, as well as all collections. Ownership is a great 
stimulus on the part of the student when properly directed by 
the teacher. At times and under proper conditions, the teacher 
may even encourage exchanges on the part of the pupils, with 
collectors living in other localities. However the teacher 
should see to it that the student does not become a mere collector 
of curiosities, a class of peojole found everywhere, but in no 
sense to be called geologists. 
The writer has usually found it best to give about one third 
of the time for this study to recitations, adapting as far as possi- 
ble the subject matter of the recitation to the laboratory work. 
For example while the class is giving special attention to the 
brachiopod, and after this family has been pretty well discussed, 
the teacher may explain other families of mollusca, when the 
limited time of the class will not j^ermit a more minute study of 
this class.
