were much less than for any of the other varieties, it probably 

 represented a fair average yield of its kind. 



The yields of Longfellow and Sanford, both grown in favor- 

 able seasons, may be considered normal in amount. The season 

 of 1908 was rather better than 1910, which would probably 

 account for the larger yield of Longfellow corn in the former 

 year. 



Pride of the North was grown during three seasons. The 

 seasons of 1904 and 1907 were both unfavorable, while 1906 

 was especially satisfactory, and in this year it yielded approxi- 

 mately twice as much dry matter as was secured in the average 

 crop of the other two seasons. 



Rustler, also grown for three seasons, showed a reasonably 

 uniform dry matter content with the highest yield in the more 

 favorable season (1908). 



Learning, grown in a favorable and unfavorable season, 

 yielded over twice as much dry matter in the favorable year. 



Brewer's dent, which evidently needs a longer growing season 

 for its maturity than the average in Massachusetts, did not show 

 a very decided variation between the two years. 



Early Mastodon and White Cap Yellow, both grown in 1908 

 and 1909, showed the larger yields in 1908, the more favorable 

 year. 



Klondike and Red Cob Silage were both grown in 1908, a 

 favorable year. Neither ripened satisfactorily, but showed good 

 yields of dry matter. The former was noticeably immature 

 when harvested. 



Wing's Improved White Cap — grown in 1909, a poor corn 

 year — did not yield well, and evidently needs a longer grow- 

 ing season. 



Eureka, grown in 1909 and 1910, showed the better yield in 

 1910. In neither case was the corn well matured, nor did it 

 show a larger yield of dry matter than some of the smaller 

 varieties that showed a very much larger percentage of mature 

 ears. 



The total yield of dry matter, rather than the green material, 

 gives a much better indication of the value of the crop for feed- 

 ing purposes. A green, immature crop will often furnish a 

 large apparent yield, but it contains an excessive amount of
