The Birch and Aspen were one-year seedlings from the woods at 
Sturgeon Bay, Wis. The Catalpa and Ash were one-year seedlings 
nursery grown. The Oaks were 12 to 15 inch nursery-grown trans- 
plants. Spaces were left for the Pines and Spruces to be set in the 
following year. The plat is designed to test Aspen and Birch, light- 
demanding trees, as nurses for the others, which are so arranged that 
the light-demanding Pine and Ash shall alternate with the shade- 
enduring Spruce and Catalpa. 
On June 30 there were living 1,435 Aspen and Cottonwood, 850 Birch, 
244 Catalpa, 237 Green Ash, 40 Oak, or 69 per cent of the trees set. 
The count of October resulted: 1,268 Aspen, 710 Birch, 247 Catalpa, 
237 Ash, 40 Oak, or 61 per cent of the number planted.
