Notice from the above table that the highest yielding sample produced 

 17.1 bushels per acre more than the lowest yielding lot. The twelve (10 per 

 cent of all) highest yielding lots yielded eight bushels more than the twelve 

 (10 per cent of all) low yielding lots and Jour bushels more than the average 

 of all 120 lots. 



The high yielding corn was earlier maturing than the lower yielding 

 lots as indicated by the lower moisture content at husking time. 



SELECTING SAMPLES FOB SEED PLOT OE FOB EXHIBIT. 



The following plan of picking out a sample of corn has proved the most 

 satisfactory of any which I have ever followed. To begin, the ears should be 

 laid out on a long board or table about fifty or one hundred' ears at a time, 

 with the butts of the ears all pointed one way and even with the edge of 

 the table or board. 



HEAVY, SOLID EARS. 



Pick up each ear, feel the weight of it, and twist it. Discard every ear 

 which is not heavy and solid. Nothing else should be considered while going 

 over the corn the first time, and every ear thrown out which is apparently 

 light or the kernels of which are loose on the cob, regardless of how nice 

 looking the ear is in other ways. I consider this the most important measure 

 of good seed corn, and while handling ears to learn whether they are heavy 

 and solid, any ear which is particularly different from the rest in size or 

 shape or in the size and shape of the kernels should be discarded. While 

 uniformity is not absolutely essential to profitable seed, it is highly desirable 

 and should be required' in samples for exhibit. 



I do not consider this matter of getting rid of irregularly shaped ears 

 and kernels next in importance to getting rid of light and loose ears, but 

 while the ears are being handled before the kernels are removed is the 

 logical time to get rid of a lot of ears which would not possibly be selected 

 for a sample for exhibit or for a seed' plot. 



BBIGHT, WELL-DEVELOPED KEBNELS. 



Two grains should be removed from the same row side by side and laid 

 in front of the ear, one with the back side up and one with the germ side up. 

 This should be done only from those ears which have been selected as the 

 specially heavy, solid, fairly uniform ears. 



At this time . select only those ears whose kernels are fully devel- 

 oped. This means those that are bright and clean from the crown to 

 the tip without any indication of starchiness except for a little way at 

 the crown of the kernel, where the starchiness naturally appears on all dent 

 corn. The backs of kernels should have the appearance which most farmers 

 describe as oily.
