the Middle West, it has no equal. For telegraph and telephone 

 poles its only deficiency seems to be a tendency toward crooked- 

 ness, but possibly this can be overcome by special treatment. As 

 a railroad-tie timber the Hardy Catalpa has not had sufficient 

 trial to demonstrate what its rank should be. Experiments have 

 left no doubt as to its resistance to decay. The only question lies 

 in its resistance to wear. 



This bulletin also contains a paper on The Disea.ses of the 

 Hardy Catalpa, by Dr. von Schrenk. 



It is interesting to note that at the beginning of the igth cen- 

 tury, when fears of a timber famine were active in Germany, 

 the rapid growth of the catalpa suggested it as a possible pre- 

 ventive, and its qualities and possibilities w^ere set forth in a 

 pamphlet, entitled : Der Bohnenbaum, ein sicheres Mittel den 

 Holzmangel mit abzuhelfen, nebst einer allgem. Einleitung u. 

 Bemerkungen iiber den Holzmangel, etc., von F. A. Resch.
