ble extent, yet there are other sections of the United States 
where the farmer has as great drawbacks, to contend with, 
such as overflows, excessive rains, etc. 
These winds are a feature of the climate of the eastern 
slope of the Rocky mountains, and cannot be expected to 
disappear or even become less frequent; neither are they 
likely^ to become more so, and, while nothing can be done 
to prevent their occurrence, steps should be taken to ameli¬ 
orate their effects, if practicable. It appears that anything 
which would furnish an extended surface from which these 
hot and dry winds c'ould absorb moisture, and thus by 
evaporation reduce their temperature as well as increase 
their moisture, would lessen their geographic extent and 
their injurious effects on vegetation. A generous growth 
of hardy timber appears to be the only material suggestion 
in this connection. If every farmer would hedge his farm 
and plant tracts of such hardy and long-lived trees as have 
been found to succeed in similar climates the injury result¬ 
ing to crops from these winds might be appreciably de¬ 
creased. Over much of the territory affected by these 
winds there is at present a scattering growth of timber, and 
this should be carefully protected and extended. 
I desire to express my thanks to Prof. Mark W. Harring¬ 
ton and Prof. Cleveland Abbe for suggestions and references 
in connection with the preparation of this memoir.
