Various, Harper's Young People, October 25…
“ Like all living things, the tiny yeast cell must eat and breathe, or it will die. It feeds, not by opening its mouth and taking in its food, but by lying bathed in it, and soaking it up through its skin. When the cook dissolves her yeast cake, and puts it into the spongy dough, she is putting the little plant into its food bath. The cells which have been so long in prison, shut up in the darkness and cold of the dried yeast, begin to look alive, and stretch themselves, and enjoy their liberty. They take kindly to their food right away, and begin helping themselves to what they find about them. ”
