Under each leaf and on alternate sides of the cane a bud

Under each leaf and on alternate sides of the cane a bud, or "eye," forms. From this eye the cane is usually propagated; for, while in tropical countries the cane forms seeds, yet these seeds are rarely fertile. When the cane is ripe it is stripped of leaves, topped, and cut at the ground with a knife. The sugar is contained in solution in the pith of the cane.
