Kentucky. 
The 13 indicated adap- 
tation areas are arranged 
with regard to climatic, 
soil and corn usage va¬ 
riations. Wide variations exist 
within many of these areas and 
these variations must be con¬ 
sidered in choosing adapted 
hybrids for specific farms.

WEST VIRGINIA— For the uplands in 
Ohio Valley territory use \V17 and 
Iowa 939. For bottom lands along 
Ohio and nearby streams use U. S. 52 
or L 31. 
KENTUCKY —On uplands, Indiana 
614, U. S. 52 and L31 are adapted. 
We offer no Hybrids suited to the bot¬ 
tom lands of this state. 
PENNSYLVANIA —For southwestern counties in val¬ 
leys and most productive uplands use W17 Or Iowa 
939. For very productive bottoms use U. S. 65. In the 
absence of adequate yield trials we suggest for trial 
only and not for general planting until after trial, in 
southeastern Pennsylvania Including territory around 
York, (Jettvsburg, Lancaster and up as far as Harris¬ 
burg, Hybrids U. S. 52 and L 31. As you go north 
choose for trial Hybrids W17, Iowa 939 and U. S. 65. 
Use earlier Hybrids on higher elevations.
