The Aspen were one year seedlings, dug in the woods near Sturgeon 
Bay, Wis., and were slightly mixed with Cottonwood. The Oaks were 
nursery grown, 10 to 15 inches. The Larch were nursery-grown seed- 
lings 10 to 12 inches; they had started growth in transit, and were 
therefore not in good condition at planting time. Spaces were left for 
the remaining conifers. It will be observed that three-fourths of the 
mixture are Aspen—light foliaged, light-demanding trees. Of the 
remainder, over one-half are also of light-demanding species, the only 
shade-enduring forms being Red Cedar and Douglas Spruce. This plat 
is designed to illustrate the effects of planting a great excess of light- 
demanding species together as nurses for evergreens, which are sup- 
posed to require the protection of other trees during their infancy. 
On June 30 the living trees were 2,752 Aspen (and Cottonwood), 260 
Larch, 33 Oak, or 74 per cent of the trees set. In October the living 
trees numbered 2,367 Aspen, 5 Larch, and 24 Oak, or 56 per cent of the 
original planting. It is hardly to be suppoged that the American Larch, 
atree of the northern swamps, will be useful so far south and under
