we don’t eat it all; we don’t plant it all

“We don’t eat it all; we don’t plant it all.”

I Am the Grand Canyon: The Story of the Havasupai People by Stephen Hirst. Grand Canyon Association. 2007. p. 50

Note: In the past, the Havasupai grew their corn in the canyon and then, in the winter, moved up to the plateau to live and ranch. Corn is carried with them for food. The corn may be stored in three chambers: that in the first is eaten during the winter, that of the second during the spring planting period, and of the third, only a little may be eaten, not all. This remainder is saved against the contingency of flood, etc.
