Not only does the total yield increase, but the quality 

 improves with maturitj^ The large group of compounds 

 under the head " nitrogen-free extract " are not all 

 equally valuable for feeding purposes. Starch and the 

 sugars are the most valuable and both increase in propor- 

 tion as the plant matures, due to the development of ear, 

 as shown by Jordan of the Maine station.'' ^
