which are not so exacting as to soil. When these things are 

 taken into consideration, it would seem the part of wisdom 

 to be cautious about introducing Catalpa on a large scale. 

 To plant a little as an experiment would do no harm; but to 

 plant it as a business proposition would be a mistake. 



106. The common Catalpa is native in Georgia; but it 

 has the same defects as the Hardy Catalpa and the addition- 

 al one of being a slower, smaller growth. It is used locally 

 for fence posts. 



107. Eucalypts. The introduction of the Eucalypts 

 from Australia is sometimes spoken of. They have been 

 grown successfully in California, but only in those parts 

 where there is little or no frost; and there is scarcely any 

 chance of growing them in any part of Georgia. Even in 

 California there is reason to believe that the rate of growth 

 has been exaggerated; and the State and United States for- 

 esters have found it advisable to warn the public against too 

 great expectations from Eucalyptus plantations.
