"Take some of the soil in your hands, powder it as finely as possible.—John, what do you find in yours?"
"I can feel grains of sand," said John.
"Do you think there is more sand or more loam?"
"I think there is more loam," said another child.
"Why do you think there is more loam?"
"Because, when I rub it between my fingers there seems to be more soft material than grains," came the answer.
"Can any one suggest a means of proving that there is some of each kind of soil in what we have here?"
Various suggestions were made, but none directly to the point.
