the same time, gain an ear that is cyhndrical and not eight-rowed 

 and taper-pointed. 



In this block there were i66 ears of suitable size for seed-saving 

 and many small ones, some of which were the third upon the 

 stalk. A photograph was secured of six sets of triplets when all 

 the ears were large enough for the table. Whether these grains, 

 are the best for planting is a matter of conjecture, but some un- 

 certainty will be removed by the ear test for vitality and strength 

 of germ that is made during the winter season. Of the whole 

 number of ears saved fifty-two were solid yellow — the first and 

 the fifth pair counting from the left being among them, showing 

 that there was no^ adherence to the "Golden Bantam" type when 

 the color agreed with it ; in other words, one character, like color, 

 is not necessarily correlated with another. The mixed ears num- 

 bered one hundred and four, which happens to> be just double those 

 with solid yellow — an instance agreeing perfectly with the expec- 

 tation under the Mendelian law. After the excluding of the white 

 grains from the parent ears there were one-third pure yellow 

 grains and two-thirds of mixed blood, but with the yellow present 

 and prohibiting the separation of the two lots. As before pointed 

 out, the yellow strain of any cross between a yellow and a white 

 sort will constantly show white grains, but in uniformly diminish- 

 ing numbers, provided that the white grains are always rejected 

 before planting. 



On the other hand, the white strain (because carrying no' yel- 

 low) is separated, at once and finally, from the ears of the blend 

 plants, provided only that the crop therefrom is successively 

 grown under isolation. In the present instance the two blocks of 

 the cross in question were grown upon the Home Grounds, and 

 the nearest hills were about one hundred feet apart. There were 

 not more than twenty grains of the yellow upon the 155 white 

 ears that were gathered for seed. In the set of six pairs of these 

 ears shown in the lower half of Plate II. there was but a single 

 yellow grain, and it may be seen in the upper half of the leftmost 

 ear. It is not advocated to have less than fifty yards between two 

 blocks of breeding corn, and much more is better, but in the pres- 

 ent instance the mixing v»'as but the slightest, and is permissible 

 for the yellow marks itself, and such grains are easily excluded.
