whose eastern eiul has l)een faulted and tilted northward. 
The facts presented in this rather limited area apply to the 
remarkable series of north and south valleys filled with 
alluvial and supposedly lacustrine sediments found through- 
out the mountainous region of Montana. IV. H. Weed. 
Celestite-Beaking Kocks — A study of the rocks — shales 
and dolomitic limestones — of the upper portion of the Salina 
epoch in central Xew York shows that celestite occurs quite 
widely disseminated throughout them (i) in the form of 
well developed crystals and (2) in small circular spots. The 
celestite was no doubt deposited simultaneously with the 
rock material. The rocks on the Island of Put-In-bay, lake 
Erie, and in southern Michigan, especially those at the 
Maybee quarry. Monroe Co., show a similar occurrence of 
celestite. When celestite bearing rocks are leached by the 
action of circulating water the celestite passes quite readily 
into solution and the rock then assumes a porous character; 
in this manner the so-called "vermicular limestones" of New 
York and also the "gashed" and "acicular" dolomytes of 
Michigan may be explained. E. H. Kraus.

Grand Prizes were Awarded to t/ie Fo/Iowiiii:^: 
The Geological Survey of India. 
The Geological Survey of France.

The Seismological Survey of Japan. 
Silver Afedals were Awarded the Following 
The Geological Survey of Louisiana. 
The University of Texas Mineral Survey. 
L^niversity Geological Survey of Kansas. 
The Geological Survey of Wyoming. 
The exhibit of the geological survey of North Carolina 
was not eligible for an award on account of the fact that 
the geologist in charge of that survey was also chief of the 
Department of Mines and ^Metallurgy at the Exposition, and 
a member of the superior jury granting the awards.
