The use of the two-circle contact goniometer in teaching crystallography
Florence Bascom
1920, American Mineralogist (5) 45-50
The two-circle contact goniometer was devised to supplement the two-circle reflecting goniometer, by furnishing a means for the measurement of medium-sized crystals not provided with sufficiently good reflecting faces for the successful use of the latter instrument. The contact goniometer has however proved itself adapted, in a greater degree even...
The preparation of illustrations for reports of the United States Geological survey : with brief descriptions of processes of reproduction
John L. Ridgway
1920, Report
There has been an obvious need in the Geological Survey o£ a paper devoted wholly to illustrations. No complete paper on the character, use, and mode of preparation of illustration has been published by the Survey, though brief suggestions concerning certain features of their use have been printed in connection...

Geology of northeastern Montana
Arthur J. Collier
1919, Professional Paper 120-B
A large region in northeastern Montana has never been thoroughly explored by geologists, owing to the fact that it is a part of the Great Plains and the belief that it is too monotonous and uninteresting to tempt anyone to turn aside from the pronounced geologic features a little farther...
Some American Cretaceous fish scales, with notes on the classification and distribution of Cretaceous fishes
T.D.A. Cockerell
1919, Professional Paper 120-I
Fish remains are extremely abundant in several Cretaceous formations of the Rocky Mountains and Great Plains, but except in the Niobrara formation of Kansas, a fish skeleton well enough preserved for description or identification is the greatest rarity. The fishes are represented by separate scales, in some places associated...
