Corn is threshed by a norag, a machine resembling a chair, which moves on small iron wheels or thin circular plates fixed to axle-trees, and is drawn in a circle by oxen.
The corn spirit is also said to be hiding in the barn till the corn is threshed, or it may be said to reappear at midwinter, when the farmer begins to think of his new year of labour and harvest.
The process by which the first of these contributions was turned into coin is still obscure; it is clear that the corn when threshed was taken over by certain public officials who deducted the amount due to the state.
In the principal rice-producing districts the rice is threshed and cleaned by machines, but in other districts more primitive methods are employed.
Rice is threshed by beating the ears on a log; other grains, with flails on mud threshing-floors.
