It would not grow here.""It is a grass, just like the other corn plants," said Willie, "with tall, hollow, jointed stems, and long pointed leaves or blades.""Teacher says," added Fred, "that after the seeds are sown in the rice- field, the men flood the whole field with water for several days. When the water is drained off, the little plants can be seen pushing their way up through the soft wet mud. "The hot sun soon begins to dry the fields, and then the men let in the water again and again, to cover them while the plants grow.""What a strange sight a ricefield must be!" said Norah.

SUMMARY

Wheaten-flour contains gluten; rice-flour contains no gluten-only starch. Gluten is the best part of the flour; it makes our flesh and bones. Rice-flour would not be fit for bread.
