Only a comparatively few plants had tasseled out up to July 

 14. Silks began appearing July 24 and by July 28 about a 

 half of the stalks in the plot were in full silk. The corn on this 

 plot, with the exception of selected rows saved for seed, was 

 cut and hauled to the factory on September 2. It was then at 

 the proper stage of growth for canning. At this date only a 

 comparatively small amount of corn from factory seed had been 

 brought into the Farmington factory. It was over a week 

 later before the factory began operating at full capacity. The 

 seed ears from selected rows in this plot were harvested for 

 seed September 22, 1908. 



From the data given it is evident that the corn in Plot I 

 was much earlier than that in Plot II. A part of this dififer- 

 ence is probably to be explained by the innate difference between 

 the two types in regard to this character already noted. An- 

 other and perhaps more important factor is to be found in the 

 fact that the Type II corn was in a new environment at Farm- 

 ington. It was not so well adapted or adjusted to Farmington 

 conditions of soil, climate, etc., as was the Type I corn. This 

 point will be more fully discussed further on. 



In the case of the corn on Plot I all of the ears were har- 

 vested for seed, the product of each row being of course kept 

 separate. After a preliminary drying at Farmington the corn 

 was shipped to Orono and given a thorough drying on racks 

 in the Experiment Station attic, as described for 1907. After 

 being thoroughly dried the ears from each row were sorted into 

 three classes, Ai seed, good seed and nubbins. The number of 

 ears in each class was counted. Then the ears of each class 

 were shelled and the weight of dry shelled corn from that class 

 determined. These weights were, from necessity, taken in 

 pounds rather than on the metric system. From the'se was 

 calculated the yield of each row in bushels of corn fit to use 

 for seed per acre. This calculation was made on the assump- 

 tion that a bushel of dry shelled sweet corn weighs fifty pounds. 



The different classes of ears were defined as follows : To 

 be put in the Ai class an ear must have a good butt and a well 

 covered tip, be of good size and shape (nearly cylindrical), have 

 the grains small and well packed and the rows straight. The 

 ears put in this class were of very fine quality. The ''good 

 seed" included all other ears which were not undersized or mis-
