160 PRACTICAL ARBORICULTURE 
Prairie States should encourage the planting of heavy and frequent tim- 
ber belts, running east and west, to overcome the effects of siroccos or hot 
winds which annually are so destructive throughout the Missouri Valley 
States. In this work Congress should be asked to extend Government assist- 
ance. 
It would be money well expended were the States to distribute seeds 
of forest trees. Since the failure of that important timber culture act can be 
wholly attributed to the neglect of the Government to provide trees and 
seeds suitable for growth upon prairie and plain, the only available trees 
being what the pioneers could find on the river bars, cottonwood and 
box elder—both totally unsuited to such changed location—it is full time that 
A FALLEN TREE IN PETRIFIED FOREST, ARIZONA: 
the Government and States should offer practical encouragement for the 
planting of trees and perpetuation of these forests, for the railways to show 
their confidence by making extensive plantations and for the farmers of the 
nation to awaken from their indifference and plant trees as a profitable farm 
crop. 
If you love your country prove it by planting trees for its adornment 
and for the benefit of your fellow men. 
The petrified forest, pictures of which are shown herewith, is in Western 
Arizona, between 6 and 12 miles southwest from Adamana, and 18 to 24 miles 
southeast of Holbrook. These two towns are on the main line of the Atchison, 
Topeka and Santa Fe Railway. 
The locality in question is covered by petrifactions of wood that retain 
the shape of the trunks and branches of trees lying like fallen timber on the 
ground. The retention of the original form is so exact in many cases that it 
is no misnomer to call it a forest, though the trees are no longer standing.
