HARDY CATALPA. 



Catalpa may be expected to thrive in western Kansas in localities 

 where permanent water occurs at a depth of 10 to 20 feet under a sandy 

 loam soil. Since its chief value is for posts, there is little use in 

 planting it outside the territory where it grows rapidly and makes 

 profitable returns.

A1LANTHUS. 



The ailanthus is of Chinese origin. The wonderful claims made 

 for it when first introduced have scarcely been justified so far as 

 western Kansas is concerned. Thousands of trees were set in timber 

 claims and elsewhere, but those which succeeded are few. The 

 ailanthus grows rapidly, is not very particular as to soil, and is 

 capable of Avithstanding considerable drought and neglect, but it 

 winterkills badly while young. Trees which manage to get past this 

 stage seem to have no further trouble. Were it not for this tender- 

 ness, alianthus \vould do very well, but even then it would hardly 

 deserve preference over several species whose especial fitness has been 

 prrpved. 



BUR OAK. 



Natural bur oak extends well westward, so it must be counted as 

 one of the more hardy species, though little used for planting. Oc- 

 casional thrifty specimens are found in the valleys, and there is no 

 doubt that success would result from more extensive trials. Several 

 species of more value are doing so well on the upland, however, that 

 there is no chance for the bur oak to equal them, and only variety is 

 to bo gained by experimenting with it.
