This table shows that the average yield of the yellow varieties was the lowest; 

 the average of the white varieties came next in order; and the average of the red 

 and mixed varieties was the greatest. Many of the white varieties were from South- 

 ern seed, and not adapted to this c'limate. The average of the white varieties tested 

 that are adapted to this locality was greater than that of the red and mixed sorts. 

 Anotlier season may change the relative position of these three classes. The average 

 yield of the medinm-niaturing varieties was more than 9 per cent less and that of 

 the early-maturing varieties 33 per cent less than the average yield of the late 

 varieties. The time required in germination by the medium-maturing varieties was 

 one day more, and that required by the late varieties two 'days more than the time 

 required by the early varieties. The per cent of stand was the highest with the 

 early varieties and lowest with the late varieties. 



(2) Selection of ears for seed. — Tabulated data are oriven for au ex- 

 periment in which seed from ears of a medium-sized yellow deut variety, 

 selected with reference to the number of rows per ear, was planted on 

 six idats. The number of rows per ear varied from 12 to 22. The re- 

 sults varied irregularly, and further tests are necessary before conclu- 

 sions can be drawn. 



(3) Distance of planting. — An account of an experiment in which a 

 medium-sized yellow dent (College Yellow) variety was grown on a 

 clay-loam upland of moderate fertility, under conditions common to 

 Kansas farms. The rows were 2.J, 3, and 3| feet apart, and the distance 

 between stalks in the row varied from 4 to 16 inches. The results are 

 summarized in tables. 



The greatest total yield of corn and fodder was obtained when the stalks stood 4 

 inches apart in rows 3^ feet apart. The yield on these rows was, omitting unimpor- 

 tant fractions, 73 bushels of corn and 3 tons of fodder per acre, but only 14J^ per cent 

 of the corn was of mari<etable size. The largest yield of corn from any distance of 

 planting was 73.77 bushels per acre, raised on row 3| feet apart, with stalks 12 inches 

 apart in the rows ; .58 per cent of the ears from this planting were marketable corn. 

 The season was favorable to close i)laniiug, as sufficient rain fell wherever needed, 

 but the land was of poor quality. » » *■ The highest yield of fodder, 3.1)3 tons, 

 was raised on rows 21 feet apart, stalks 4 inches apart in rows. Wliere grain alone 

 is desired, the wider planting will always give the greatest yield of marketable corn. 

 The yield of fodder from the rows with stalks 4 inches apart was more than double 

 the yield from the rows with stalks 12 or 16 inches apart, while its value for feed was 

 mach more than twice that of the fodder from the wide planting. Tlie valuable 

 portion of ibi feed, when corn is cut for fodder, is contained in the leaves and ears ;
