Cheerfulness on the treadmill as the wheel goes round More fortunate than his brother farmer seen above, this man possesses a water-wheel whereby water may be pumped into the channels that irrigate his fields. Daily he may be seen with his sons cheerily toiling on the treadmill and mentally calculating the value of each foot-pound of energy as it will be represented later on in strings of cash for his rice.
