 attack upon the Catalpa speciosa, and from the prominence of the paper, is cal- 

 culated to do great harm by discouraging the planting of these trees by others.

The hundred thousand people from every portion of the world who saw the 

 catalpa exhibit at the St. Louis Exposition, saw many ties which had been in 

 constant service in several great railway tracks for thirty-two years, ten years of 

 which were under heavy traffic, supporting ninety-pound rails, and yet without 

 tie-plates. 



The rapidity of growth of Catalpa speciosa has been abundantly proven. \Ye 

 instance one tree, which was planted in a dooryard at Cambridge City, Indiana, in
