spring. One-year trees rnay be transplanted readily, but older trees, 

 unless previously transplanted, succeed but poorly. 



Plate 1 shows a grove of Black walnut trees which stands on a 

 farm adjoining the College farm. The soil is of good quality, for up- 

 land, and the tree growth is equal to any walnut timber in this locality, 

 except that in the rich creek bottoms. The trees stand where the 

 nuts were planted in 1869, and have been thinned occasionally, fur- 

 nishing some fuel. 



At present the trees average about eighteen feet apart, have good, 

 straight trunks, and are vigorous, promising trees. They average 44 

 feet high ; 9 inches in diameter at the ground, 7f inches in diameter 

 at two feet, and 6| inches at six feet from the ground. 



The largest trees are around the edge and in the lowest part of the 

 grove. A number of the best measure from 48 to 52 feet in height ; 

 from 12 to 15 inches in diameter at the ground, from 10 to 13 inches 

 at two feet, and from 9 to 12J inches at six feet. 



The poorest trees in the grove measure from 21 to 30 feet in height ; 

 from 4 to 6 inches in diameter at the ground, from 3 to 5 inches at 

 two feet, and from 3 to 4J inches at six feet from the ground. 



OSAGE OKANGE. (Toxylon pomiferum.) 



From the report of 1886. 



"The Osage orange plantation stands as made, trees three to four feet apart, 

 in rows four feet apart. No systematic thinning has been made. The trees aver- 

 age over 20 feet in height, and, as shown by measurement at a height of one foot 

 from the ground, over 10 inches in circumference. As will be understood, they 

 are much more generally branched low and the trunk often divided at the height 

 of one foot from the ground. The lower branches do not so readily kill out by 

 shading as in other trees." 



The later growth of the Osage orange plantation of 1872 has been 

 such as to warrant its being recommended for general planting. It 

 has readily replaced itself from coppice growth, when cut. Some of 

 the trees now growing in the 1872 plantation show that two good posts 

 have been cut in former years and the trees now standing would each 

 make several good posts. 



At the present date, 1903, this planting, containing somewhat less 

 than one-half acre, contains 200 trees which would make 350 posts. 



The trees of the original planting average 35 feet in height and 11 

 inches in diameter one foot from the ground. At five feet from the 

 ground the average diameter is 7 inches. 



For fuel and posts the wood is more valuable than any other grown 

 in the artificial forests. The wood burns well even when green, and 

 lasts well.
