The varieties of the 6-rowod group were fully headed about July 10, 

 and those of the 2-rowed group about July 15. The 6-rowed group 

 reached maturity about August 2, and the 2-rowed group about 

 August 8. There has been little difFerenco in the height attained 

 by the diff(!rent varieties. The 2-rowed varieties have tested con- 

 siderably higher in weight per bushel than the 6-rowed hulled 

 varieties. The 2-rowed group has yieldcu] liiglicr than eitlun- of the 

 other groups. All varicf ics luivc [)roduced about the same quantity 

 of straw per acre.
