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.

AILANTHUS. 
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 withstanding 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 would do very well, but even then it would hardly 
deserve preference over several species whose especial fitness has been 
proved. 
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 be gained by experimenting with it.
