with only a cloudiness showing through the colorless skin, and 

 frequently so indistinct that the person who attempts tO' separate 

 the colored from the uncolored will feel that there is a possibility 

 of some of the crossed grains showing no signs of the fact so far 

 as the color goes'. This assumption seems to account for some of 

 the results that arc met with in the breeding of different colored 

 corns, 



'•'CAOCO" CORN AND PROPOSED CROSSINGS. 



In the lower left-hand corner of Plate IV. are shown five ears 

 of the "Calico" field corn, which was grown the past season as a 

 breeder row upon two sweet sorts, namely, the sweet strain 

 of "Iowa Silver-Mine" upon "Country Gentlemen" and the 

 "Stoweill's Evergreen" standing in parallel rows upon either side 

 of the "Calico." Thisi latter sort is a good sized dent co'm, with, 

 the gi-ains most variably marked ; the ears as such vary froaii those 

 that are almost free from color in the skin of the grains (11) to 

 those that are solid red (15), while others have each grain marked 

 quite similarly with fine chocolate lines. Among the fifty and 

 more ears secfured there were no two- alike in the markings ex- 

 cepting when they w^ere borne by the same stalk, and then they 

 closely reseanble each other, even to the minute details of the mark- 

 ings ; this' kind of coloration is not a grain peculiarity, but of the 

 whole ear, and all the ears, or in other words, is a plant peciuliarity, 

 and when thisi variety is crossed upon sweet sortsi it does not show 

 any xenia of those markings. 



The "Calico" seed employed was mixed as to the color of the 

 endosperm, some grains being white and others yellow, and this 

 fact is prominently enforced by the starchy kernels that appear in 

 the sweet corn ; that is, some are plain white dent and others yel- 

 low. In the case of the "Calico" ears, many of the gi-ains doubt- 

 less carry the sweet potency under cover of the starchy quality; 

 the yellow and white grains are disposed without order on any ear, 

 and the yellow as a rule is evident, excepting where the coat is 

 solid red, in which instanoei a removal of the thin wall of the ovaiy 

 by scraping or weak potash shows that tlie yellow or white endo- 

 sperm is beneath. 



When there are two setS' of colors — one a, plant quality expressed 

 in all the grains, in some degree of similarity, and the other a
