"Yes, you squeezed the bag of flour in the basin of water," said Norah, "and washed out all the starch into the water.""I am going to do it again now," said Fred. " You watch me."After squeezing and kneading the bag for some time, Fred said, "I think I have got most of the starch out now. Let us open the bag and look inside." He did so, and showed his sister a thick, sticky substance left behind in the bag. "This," said he, "is gluten. It is the most important part of the flour. It is the gluten that makes our flesh and bones, and all the parts of our body. Wheat and oats are the best of the corn grains for food, because they containmore gluten than the others.
"Do you know what I have in this saucer?" "That is some rice," said Norah.
"Yes," said Fred. "Rice is another kind of grain. Teacher washed the starch out of some rice-flour in class today, but when he opened the bag there was nothing left inside. The rice-flour is pure starch. It contains no gluten. Rice-flour would not be fit for bread.""Where does rice grow, Fred?" asked Norah.
