When planted at greater distances the trees have made better growths. 

 On the College campus the Honey locust has shown a tendency to 

 form wide-spreading, rather low trees when planted alone. 



The largest trees of this species were planted before the College 

 owned the land, and, as nearly as can be ascertained, are forty years 

 old. These trees are growing in upland soil of medium quality, and 

 stand far enough apart to allow symmetrical development. They 

 average slightly over 40 feet in height, with a spread of about forty 

 feet. The diameter at four feet from the ground averages 22 inches. 

 They branch low, but are very handsome and altogether desirable 

 shade-trees. 



The best growth noted upon the campus is that of a tree which is 

 one of a row of seedlings grown in 1893. At this date, August, 1903, 

 it measures : 



Height 34 ft. 6 in. 



Diameter at ground 10 inches. 



" at 5 feet. 8 " 



" at 10 feet 5 " 



The following record of a Honey locust planting in Lincoln county 

 is a fair average of numerous observations made in various parts of 

 the state. Trees one year old from seed were planted in 1886 on up- 

 land soil of fair quality. The distance was four feet apart ; rows eight 

 feet apart. Trees thinned in 1900 to eight feet each way. No culti- 

 vation since the fifth year. Dust from a well-traveled road has caused 

 some injury in very dry seasons. Greatest height, 29J feet ; average 

 height of sixty consecutive trees, 22 feet and 2 inches ; greatest di- 

 ameter of sixty consecutive trees, at four feet from the ground, 6 

 inches ; average diameter at four feet from the ground, 4 inches. It 

 would seem that this combination of the qualities of durability, re- 

 sistance to drought and fair rate of growth make this one of the 

 most desirable trees for planting in western Kansas. 



The Honey locust is readily propagated from seed. Seed planted 

 in the fall has usually given a fair stand, but the germination of seed 

 in succeeding seasons is sometimes troublesome. Soaking in water 

 heated to 150 deg. Fahrenheit has given good results. 



Many Honey locust trees are thornless. This characteristic may 

 usually be noticed in the nursery row or seedling bed, and it is well 

 to select such trees for shade and street trees. Seed from the thorn- 

 less trees has produced many trees with thorns, though the proportion 

 of thornless trees is greater than from the seed from thorny trees.
