grow. Young trees showed a more rapid increase. Twenty miles southeast 

 of Denver is another cedar stump the same size as this, while twenty-two 

 miles south of Denver on the Colorado and Southern Railway is a log of 

 mammoth size. This is on Cherry Creek near the old Santa Fe trail. Rev. 

 M. Hamilton, a collector of fossils, first discovered its character in 1866. It 

 \vas in three sections, broken in falling. It has been mostly removed, blasted 

 with dynamite and carried away. My informant, Mr. VV. N. Byers, of Den- 

 ver, described it as being when he first saw it in 1868, 90 to 93 feet long and 

 from 20 to 22 feet in diameter, partly imbedded in the earth. 



There are many other wood petrifactions in Colorado, at Boulder, about 

 Golden, and some at Middle Park, which are from three to five feet in 

 diameter.

Near Sims, Morton County, North Dakota, on the Northern Pacific 

 Railway, are quite extensive petrifactions. 



At Fossil Station, Uinta County, Wyoming, on Ham's Fork of Green 

 River, are others. On Yakima River in eastern (arid) Washington and in 

 eastern (arid) Oregon are large numbers. 



A party of California prospectors, while searching for minerals, reported 

 in 1860 an immense petrified tree in a defile in Northwestern Nevada, not far 

 from the Oregon line. This, according to their report, was larger than the 

 largest sequoia now living. Numerous other stumps and trees were seen 

 in the same vicinity. This is an extremely arid locality and but seldom 

 visited.
