(3.) The common impression seems to be that our varieties 

 of field corn and sweet corn which mature in this latitude and 

 which are harvested for the silo after the plants have reached 

 maturity or nearly so, contain much less water and more dry 

 matter than the larger varieties of Southern corn. "While these 

 experiments show a difference in the percentage of dry matter in 

 favor of the Field Corn and Sweet Corn, the difference has not 

 proved to be as great as many would expect. The average results 

 for three years show that the Northern field corn contained only 

 two pounds of dry matter per hundred more than the Southern 

 corn at the time the crops were harvested. 



(4.) These experiments illustrate very fully the already fami- 

 liar fact that the weight of a green fodder crop is not a correct 

 standard for judging its value. For instance, 18,940 pounds of 

 Hungarian grass contained more than a third more dry matter 

 than 31,695 pounds of rutabaga turnips, and practically as much 

 dry matter as 32,000 pounds of Southern corn.
