feet 5 inches in height and 1 T % inches in diameter at one foot from 

 the ground. Where left unthinned, the stronger trees have practically 

 overgrown the weaker ones, and at this writing, November 1903, at 

 least one-third of the trees are crowded out. 



In November 1903, 100 Scotch pines averaged 18 feet 4 inches in 

 height and 3^ inches ki diameter at four feet from the ground. The 

 tallest trees are 24 feet in height ; the greatest diameter at four feet 

 from the ground is 5J inches. 



One hundred Austrian pines measured November 1903, averaged 16 

 feet 4 inches in height and 4J inches at four feet from the ground. 

 The tallest trees are 21 feet in height ; the greatest diameter at four 

 feet from the ground is 5| inches. 



These two pines, the Scotch and the Austrian, seem nearly equal in 

 hardiness and rate of growth. The choice for setting would depend 

 upon other considerations. The Austrian seem more nearly certain 

 to form straight, regular trunks when planted singly or in small 

 groups, but in larger plantings the Scotch pine is little inferior. The 

 Austrian is rather darker and heavier in appearance; perhaps too 

 much so for best artistic results in small plantings. The Scotch pine 

 is morfe variable, usually of a lighter color and more graceful and less 

 stately appearance. 



Tables II and III give a comparison of the rate of growth of the 

 Austrian and Scotch pines planted on the College campus :
