You may be sure that the Professor did not object to activities in this direction; and they had long ago learned his peculiarities, particularly not to venture any information voluntarily, so the boys concluded to make bread on their own knowledge. They had often seen bread made.
"All you have to do is to mix up the flour with a little water, put some rising in it and let it stand until it raises and then bake it."
"That's all well enough, Harry, I suppose we can do all that, but where shall we get the yeast?"
"That's so; yeast is necessary; I suppose we shall have to see the Professor, after all; but hold on; I have seen sour milk used, George."
"So have I; but I think mother used something else with it."
"Well, there we are; who would think we could have trouble with such a simple thing as making bread?"
The Professor came smiling. "You want to make bread, and the only thing that troubles you is to raise it so it will be light?"
"Wouldn't it be bread if you didn't raise it? You know the Jews used unleavened, or unraised, bread."
"But we want regular bread, of course, and we want to know what to use to raise it with."
"I don't see that you particularly need anything."
