YIELD (SMALL SAMPLE AREAS). 
The yield of the black willow varies greatly. Typically mature 
willow is usually found with cottonwood, occasionally in extensive 
pure stands. Even when grown with cottonwood it often occurs in 
pure groups or pockets of from 10 to 100 trees. Of the sample plots 
listed in the following table, Nos. 1, 2, and 3, near Helena, Ark., were 
selected from an area of several hundred acres on which willow 
occurred in varying amounts, averaging about 33 per cent of the total 
stand. In plots 4, 5, and 6, near Rodney, Miss., the willow was 
mixed with cottonwood and made up only about 8 per cent of the
