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...

A contribution to the geology of northeastern Texas and southern Oklahoma
Lloyd William Stephenson
1919, Professional Paper 120-H
The region in central and northeastern Texas and southern Oklahoma known as the Black and Grand prairies abounds in features of interest to physiographers, geologists, and paleontologists, and the pioneer investigators of this region must have experienced renewed satisfaction in each day's exploration. The reports of Joseph A. Taff,...
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...
