approach the nurse trees in height, and without exception the leading 
branch is well in advance of the laterals, and the trees are making a 
vigorous growth. lven the few that are entirely shaded (overhead) by 
the Boxelders are in good condition. The Elms average somewhat 
taller than the Boxelders in this plat. They show the formative effect 
of the nurse trees in their straight trunks and high -ranching.

This plat contains a good stand of Scotch Pine and White Birch, the 
nurse trees being Silver Maple and Cottonwood. The great majority of 
the Cottonwoods failed during the drought years of 1894 and 1895, but 
those which remain are the tallest trees in the plantation. The Birches 
are second to the Cottonwoods in height, and are the handsomest trees 
in the entire plantation. They were purchased for Yellow Birch, but 
proved to be European White Birch. The tree is a native of cool, 
moist climates, and its vigorous growth thus far is an illustration of 
the ability of species to succeed under widely varying conditions. The 
Maples froze back to the ground the first winter, and have since grown 
with several trunks, which has increased their shade but has not 
improved their appearance. They have withstood the drought years 
better than Boxelder, but they have been injured somewhat by sun- 
scald. They do not equal Boxelder as a nurse tree. 
The Scotch Pines were bought as seedlings 10 to 12 inches high, and 
were first planted in nursery rows and heavily mulched. The second 
spring favorable weather was chosen for setting them in the plat with 
the other trees. The Pines are unequal in growth, some being almost
