The judicial system was very similar to that which obtained elsewhere in America. In each province was an upper court, consisting of a chief justice and associates, appointed by the governor; from this an appeal might go in important cases to the governor and council, and in causes involving £200 or over, to the king in council. Below the upper court was a regular series of courts, ranging down to the local justices of the peace. Justice was cheap, and court practice simple. In New York, the quality of both bench and bar was inferior, and remained so down to the Revolution; the judges had often no legal training, and the law was not recognized as a profession. In Delaware, New Jersey, and Pennsylvania men of ability and character were engaged on the bench and at the bar, and their calling won universal respect. Penn brought out two physicians with him, and in the Quaker colonies the art of medicine had from the first an honorable standing; but in New York physicians were not licensed until 1760. In all four colonies the clergymen for the most part were zealous, upright men, of learning and ability, and took high social rank. Sidenote: Agriculture and manufacturing. Except in New York, where trade was equally important, agriculture was the chief industry; but as the soil was fertile and the average farmer consequently careless, farming was, except among the painstaking Quakers of Pennsylvania, in a low condition. The principal crop was wheat, although there was much variety in farm products, and New Jersey raised large herds of cattle on her broad lowland meadows. There were many small manufactures for domestic use, the most important being among the Germans of Germantown, who made, in a small way, paper and glass, and also some varieties of knit goods and coarse cloths; the spinning-wheel was a familiar household machine, for homespun was much worn by all except the rich. But the bulk of manufactured goods was imported from England and the continent of Europe. Little picturesque windmills, with broad canvas sails, after the Dutch fashion, were numerous. Many of the Maryland and Virginia colonists came long distances to patronize the Pennsylvania mills. It was not until 1720 than an iron furnace was erected in the latter province,--the first in the middle group of colonies. Sidenote: Trade and commerce.
