Our Hidatsa word for corn is ko´xati; but in speaking of any variety of corn, the work ko´xati is commonly omitted. In like manner, atạ´ki means white; but if one went into a lodge and asked for “atạ´ki” it was always understood to mean soft white corn.
Of the nine varieties, the atạ´ki, or soft white, was the kind most raised in our village. The ma´ïkadicakĕ, or gummy, was least raised, as almost its only use was in making corn balls.
In my father’s family, we raised two kinds of corn, tsï´di tso´ki, or hard yellow; and atạ´ki, or soft white.
The names of the varieties suggest pretty well their characteristics. The atạ´ki aku´ hi´tsiica, or white-with-light-red, was marked by a light red or pink color toward the top or beard end of the ear. The name pink-top which you suggest for this variety will, I think, do for an English name, if the literal translation of the Indian term is, as you say, rather clumsy.
We planted each variety of corn separately. We Indians understood perfectly the need of keeping the strains pure, for the different varieties had not all the same uses with us.
How Corn Travels
We Indians knew that corn can travel, as we say; thus, if the seed planted in one field is of white corn, and that in an adjoining field is of some variety of yellow corn, the white will travel to the yellow corn field, and the yellow to the white corn field.
Perhaps you do not understand what I mean by corn traveling. Well, let us suppose that there are two fields lying side by side, the one in yellow, the other in white corn. When the corn of the two fields is ripe, and the ears are opened, it will be found that many of the ears in the yellow rows that stand nearest the white field will have white kernels standing in the cob; also, in the rows of white corn that stand nearest the yellow field, there will be many ears with yellow kernels mixed in with the white kernels.
We Indians did not know what power it was that causes this. We only knew that it was so. We also knew that when a field stands alone, away from other fields, and is planted with white corn, it will grow up in white corn only; there will not be any yellow grains in the ears. And so of any other variety.
