April 1902.] The Hardy Catalpa. 143 



feet long, contained 251 trees, having 85 good posts. Ten rows, 8x4 

 feet, 117 feet long, grew 228 trees, having 280 good posts. The trees 

 in the wider rows have a greater average height and diameter ; the 

 average diameter in the planting 4x8 feet apart being slightly under 

 six inches; in the rows, 4x4 feet apart, the average diameter is nearly 

 four and one-fourth inches. The average height is about the same, 

 eighteen feet. 



In some cases, where trees were thinned by cutting off just above the 

 ground, the new shoot from tne stump made such a straight, rapid 

 growth that the cutting back seemed to secure the formation of 

 straighter posts. As might be expected, the second-growth posts 

 grow to a suitable size for use in less 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 Col- 

 lege 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 a 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 5 shows a clump of catalpas near the Domestic Science build- 

 ing. The soil is of only medium quality, and the trees are of a very 

 good size for fourteen seasons' growth. 



Plate 6 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 36J feet high, 15 inches in diam- 

 eter at two feet from the ground, and 13J inches at four feet from the 

 ground. The yellow tint is quite conspicuous 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 conspicuous 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, in- 

 clining to be shrubby. Probably the best results in the way of foli- 

 age would be secured by cutting back severely and growing as shrubs, 



The Japanese catalpa, Catalpa kcempferi, has made rather a low, 

 shrubby growth on the College campus. It presents a fine appear- 

 ance 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 sledder pods giving the branches a drooping effect. 



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