Your Uncle Jon placed you in charge of the cows, because as it turned out milk was very expensive in the town where he came from. Even the city prices of milk couldn't compare to what your uncle sold. You decided to give it a try, since you didn't have much else to do while you were on Jon's farm for the weekend.
The cows were out in the pastures, however when you see them, you discovered that there were only female cows. They didn't have any rings in their noses, they had different colored collars on that had bells attached to them, and they were basically different colors, while eating the grass on the ground. The problem was, you didn't see any bulls in the pastures that would want a mate with these bulls. Your uncle probably couldn't afford one. To this, you headed to the barn, to grab an empty pail.
