the spring is usually most successful, and should be done before the 

 buds are much swollen. As with all trees that are being transplanted, 

 care must be taken to prevent drying. If the roots be exposed for 

 "only a few minutes to the sun or drying winds, the chances for success 

 may be seriously reduced. 



CONCLUSIONS. 



The catalpa plantings made by the College and the Experiment 

 Station have given encouraging results. On very poor soil the ca- 

 talpas have been a paying crop. Almost any other cropping of this 

 land would have reduced its fertility, while the crop of trees has un- 

 questionably been beneficial, both by preventing washing and by the 

 addition of some humus. 



On good soil the growth has been proportionately better. The 

 trees have made a more rapid and vigorous growth, producing trunks of 

 suitable size for posts in from seven to ten years, and in twenty years 

 trees have grown to a size sufficient for heavier uses, or for lumber for 

 finishing or cabinet work. 



The most desirable distances for planting probably vary somewhat 

 for different soils and locations. Rows eight feet apart, with the trees 

 five or six feet apart in the row, would seem, from our observations, 

 to be a good distance for general planting. With the rows eight feet 

 apart, corn or some other rowed crop may be planted for at least one 

 season. 



Good clean cultivation should be given for several years. Atten- 

 tion should be given to trimming the trees, to avoid low branching. 



Cutting back to the ground usually secures a rapid growth of 

 smooth straight wood. 



The young trees are easily raised, transplant readily, grow rapidly ? . 

 and endure extremes of drought, heat, and cold.
