(Continued) 
MERCER YELLOW FLINT

This is a very old 10 to 16 row New England Flint. Matures about 
the same time as Haney Strain, Minn. No. IB. It is one of the largest 
eared flints. Common with other flints, it suckers profusely. Stalk height 
about the same as Haney. Adapted to northern and central Wisconsin 
and Minnesota, and to North Dakota and Montana. It has made the highest 
average yield of any variety over a long period at the North Dakota 
Experiment Station. 
NORTHERN YELLOW DENT, WISC. NO. 25 
90 Day 
Originated by Prof. E. J. Delewiche at the Spooner and Sturgeon 
Bay, Wisconsin branch, Experiment Stations. It is adapted to Northern 
Wisconsin and similar areas. It is approximately 10 days earlier than 
Minn. No. 13. Ears average 12 rows of grain and kernels are quite reddish 
on the sides, rather shallow and broad. Stalk height is about 1 to */2 ft. 
shorter than Minn. No. 13.
