8 FAIRBANKS AND RAMPART QUADRANGLES. 
region in 1902, has added some features to the geologic map, and 
also material regarding developments in the Fairbanks and Rampart 
regions during 1907. Mr. Prindle has presented the salient features 
of the geology, so far as known, in simple language devoid of techni- 
calities. A more elaborate discussion of the scientific results is in 
preparation. A section by F. L. Hess on the placers of the Rampart 
region, which was originally printed in Bulletin No. 280, " The Ram- 
part gold placer region, Alaska," is here reprinted, in order that all 
the placers in the region indicated by the maps may be covered in 
the written description. 
As the publication goes to press, it has been possible to add to it 
the preliminary statement of C. C. Covert on the water resources of 
the Fairbanks region, based on surveys made in 1907.
