NORTHRUP, KING & CO’S KINGSCROST HYBRID SEED CORN 
ripened in our trial grounds from 1923 to 1936, planted practically the 
same time each year on the same farm. Notice how the same corn matured 
3 weeks earlier in the warmest season than in the coldest season. 
If you have been growing a hybrid maturing later than native ac¬ 
climated varieties, do you think you could mature it in a season when 
maturity might be 3 weeks later?
