Mr. George F. Kunz read a paper entitled, 



ON THE AGATIZED WOODS, AND THE MALACHITE, AZURITE, 

 ETC., FROM ARIZONA. 



(Richly illustrated with specimens of all, and with microscopical 

 sections of the fossil woods.) 



Undoubtedly one of the greatest of American wonders is the 

 silicified forest in Arizona, known as Chalcedony Park — a park 

 only in name, however, for the giant trees which once grew there 

 have long since fallen and been silicified into agate and jasper. It 

 is situated eight miles south of Corriza, a station on the Atlantic 

 and Pacific Railroad, in Apache County, Arizona, twenty-four 

 miles southeast of Holbrook. Tliis marvellous deposit of prob- 

 ably a million tons of silicified trees covers a thousand acres.
