Section of board from catalpa tree grown on Agricultural College campus. 



Conclusions. 



The catalpa plantings made by the College and the Experi- 

 ment Station have given encouraging results. On very poor 

 soil the catalpas have been a paying crop. Almost any other 

 cropping of this land would have reduced its fertility, while 

 the crop of trees has unquestionably been beneficial, both by 

 preventing washing and by the addition of some humus.
