Once a cartman was driving his cart along a muddy road. It was a rainy day. Suddenly one of the wheels got stuck in a mud-hole. The cartman beat the bullocks severely to make them pull out the cart, but in vain. At last he sat helplessly by the roadside.
He prayed to god Hercules for help. The god appeared before him. He advised the cartman to put his shoulder to the wheel and try to push the cart out. The cartman acted upon his advice. The bullocks too pulled hard and the cart began to move on.
