22、Once upon a time a poor farmer taking a sack of wheat to the mill did not know _ _ 21 _ _ to do when it slipped from his horse and fell _ _ 22 _ _ the road. The sack was _ _ 23 _ _ heavy for him to lift, and his only hope was that presently some one would come riding by and lend a hand.
It was not long _ _ 24 _ _ a rider appeared, but the farmer's heart sank when he recognized him, for it was the great man who lived in a castle near by. The farmer would have dared to ask _ _ 25 _ _ farmer to help, or any poor man who might come along the road, but he could not beg a favor of so great a man.
