Many general customs existed in the early colonies which were simply exemplifications of neighborliness put in legal form. Such were the systems of common lands and herding. This was an old Aryan custom which existed many centuries ago, and has ever been one of the best ways of uniting any settlement of people, especially a new settlement; for it makes the interest of one the interest of all, and promotes union rather than selfishness. Common lands were set off and common herds existed in many of the Northern colonies; cowherds or "cow-keeps" were appointed and paid by the town to care throughout the summer for all the cattle owned by the inhabitants. This was an intelligent provision; for it saved much work of individuals during the months when farmers had so much hard work to do, and so short a time to do it in. In Albany and New York the cowherd and "a chosen proper youngster"--in other words, a good, steady boy--went through the town at sunrise sounding a horn, which the cattle heard and knew; and they quickly followed him to green pastures outside the town. There they lingered till nearly sunset, when they were brought home to the church, and the owners were again warned by the horn of the safe return of their cattle, and that it was milking time. Sometimes the cowherd received part of his pay in butter or cheese. In Cambridge, Massachusetts, Cowherd Rice, in 1635, agreed to take charge of one hundred cows for three months for ten pounds. The town also paid two men or boys to help him the first two weeks, and one man a week longer; he kept the cows alone after that, for the intelligent cattle had fallen into habits of order and obedience to his horn. He had to pay threepence fine each time he failed to bring in all the cattle at night.
