A ltl<.ok nf a cruss of "lilack Pop" upon "Zigzag" sweet corn was 

 grown. Itut it was too near a row of maple trees to give satisfactory 

 rt'snli>. The small ears secured, however, showed the usual three- 

 <juarters of the <lark tlint grains, and nearly all had the rows usu- 

 allv fourteen, distinct excepting occasionally at the tip, w^here the 

 grains were irrcgidarly jjlaced. The exceptional ears were of the 

 true zigzag type, an<l suggest the thought that the straight-rowed 

 oar is the ofdcr or original arrangement of the grains and the 

 y.igzag is a recessive type. Some of the ears had the grains with 

 i*liar]) tii)s, resembling the "Eice" type of poi>corn, but those with 

 r'.nndcd or smooth ti])S were in the large majority. 



A PRIMA.RY BREEDING PLOT OF SWEET CORN. 



Tlic following twenty-eight (28) numbers occupied the north- 

 cast corner of the Xew Land, that is, the eastern end of Strip III. 

 Each number made a row of fifteen hills across the strip. The 

 breeders were "Cory Red Cob" (16) and "Pride of Nishua" 

 (14.')), which make Row 5, cutting all other rows at right angles, 

 ami a yellow sort from liliode Island (l-i-2) with "Silver Mine" 

 (144), the latter two making Row 10, parallel with Row 5. In 

 other words, hills 5 and 10 of each row across the strip were passed 

 over in the general ])lanling and afterwards filled in with the 

 breeders, as above stated. Each of the two breeder rows contained 

 alternate hills of the two sorts, namely, breeder row 5 had the odd 

 hills <,f -Cory Red Cob" and the even hills "Pride of Nishua," 

 and breeder row 10 received for odd hills the "Rhode Island Yel- 

 low" and for even hills the "Silver Mine." 



The point in particular was to study the standard varieties of 

 >weef eorns as to characteristics and expose them to the pollen of 

 all of the breeders. The "Cory" difi'ers from all other varieties of 

 Mveet corn m the pidi in having its grains of a reddish yellow upon 

 a cob of the same color. The "Pride of Nishua" is a standard field 

 corn, the seed ears of which were secured from a corn breeder in 

 [owa.^^ in thi< the -rains were yellow upon a cinnamon-colored 

 <'ob. The "lihode Island Yellow," as its name suggests, is a genu- 

 ine sweet corn with the ye]l.,w grains, and the "Iowa Silver Mine"
