ACME BROOM CORN. 
The Acme broom corn was developed from a selection made in a 
field of Standard broom corn by Mr. A. H. Leidigh, at Channing, 
Tex., in 1906. It resembles the Standard variety in the length and 
texture of the brush and the Dwarf in the height of the stalk. The 
peduncle, or main stem, is less firmly attached to the upper node, or 
joint, than it is in the Standard broom corn. This makes it possible 
to harvest it in the same way as the Dwarf variety. The Acme re- 
quires less water than the Standard, and it produces a brush of good 
length and quality under the average seasonal conditions obtaining 
in the southern Great Plains. These characters make it adapted to 
conditions in that section of the United States. It is now being 
grown there commercially to a limited extent. Plants of this variety 
are shown in figure 4. 
The results with the Acme broom corn obtained in the varietal ex- 
periment conducted at the Woodward Field Station during the 5- 
year period from 1914 to 1918, inclusive, are shown in Tables VI and 
VIII. It will be noted in Table VI that in the 5-year period the 
row space per plant ranged from a minimum of 5.5 inches in 1915
