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
