382 The American Geologist. June, 1905 
marble is too delicate a material for the exterior of struc- 
tures in the trying climate of the eastern United States. 
Fortunately for those interested in the new Museum 
building, there has been developed recently a quarry 
of a very light • muscovite-bearing granite at Bethel, Ver- 
mont, and it is to contractors controlling this quarry that 
the award for the first two stories above the basement of 
the new structure has been given. This stone when in the 
quarry weathers to a whiteness almost equal to that of 
marble, but with a softer and more mellow tint, and has, at 
the same time, the appearance of strength and massiveness 
•of granite. 
The basement story of the building is to be constructed 
of a light-pink granite from Milford, Mass., and the upper 
portion of a light-gray stone from Mount Airy, North Caro- 
lina. G. p. M. 
Notes on Goldfield, Nevada. 
The following notes are based upon an examination of 
a few days, only, and are not presented as in any way an 
exhaustive report upon the district. 
The Goldfield district is situated about twenty-five (25) 
miles south from Tonopah, near the boundary line between 
Nye and Esmeralda counties, Nevada. 
The first discoveries of gold ore were made in the 
spring of 1903. The first rich ore was taken out early in 
1904; and during that year, there was produced high grade 
ore ($100.00 per ton or more) to the value of about $2,200,- 
000 net smelter returns. This ore was taken out mostly by 
leasers, hauled by team to Tonopah and shipped from there 
over a narrow gauge railroad. The chief producers during 
1904 were 
The Jumbo Production about $700,000.00 
The Florence " " 650,000.00 
The Combination . . " " 600,000.00 
The January " " 187,000.00 
These properties are all near the south end of Columbia 
mountain. Other properties in the district have produced 
very rich ore, the "Sandstorm" for example, which lies 
north of the mountain, and from which a shipment of about
