time than was required for the first growth of trees. The 

 comparative value of the first and the second growths for posts 

 is a subject for further observation. 



Catalpas have been used for shade and ornamental trees on 

 the College campus, around the buildings, and in the clumps 

 and belts. Given a sufficient amount of room, in a good soil, 

 the catalpa trees have made a fairly rapid growth, and usually 

 have made pleasing, symmetrical form. The foliage, while not 

 especially heavy, is sufficient for good shade, and the blossoms 

 add to its appearance in their season. Plate 34 shows a clump 

 of catalpas near the Domestic Science building. The soil is of 

 only medium quality, and the trees are of a very good size for 

 fourteen seasons' growth. 



Plate 35 shows a very fine specimen of the Golden catalpa; 

 the tree is graceful and symmetrical, rather heavier in foliage 

 than most of the trees of this species. It is 36 feet high, 15 

 inches in diameter at two feet from the ground, and 13^ inches 

 at four feet from the ground. The yellow tint is quite con- 

 spicuous in the early part of the season, but is much less so 

 after midsummer. Young trees show the yellow shade much 

 more than the older ones. 



Specimens of the Purple-leaved catalpa have been grown on 

 the College campus. The purple tint is much more conspic- 

 uous in the younger trees, and with these the colors" are most 

 vivid in the early part of the season. The specimens grown 

 here have been grown on a soil of medium quality, and have 

 made but a moderate growth, inclining to be shrubby. Prob- 

 ably the best results in the way of foliage would be secured 

 by cutting back severely and growing as shrubs. 



The Japanese catalpa, Catalpa kcemyferi, has made rather a 

 low, shrubby growth on the College campus. It presents a fine 

 appearance when in bloom, carrying a heavy load of flowers. 

 In the fall, after the leaves are fallen, it presents a rather 

 unique appearance, the large number of slender pods giving 

 the branches- a drooping effect. 



A number of Teas' hybrid catalpas were set in the timber 

 belts on the College campus. These have been somewhat va- 

 riable in form and growth, but have, on the whole, made good 

 growths and fine trees. 



Some of the trees set in a cooperative experiment with the 

 division of forestry, Department of Agriculture, are evidently
