He was soon, however, given very important employment in spite of his age. He had made himself famous in many varied spheres, from almanacs and stove-making to treaties of alliance. Nothing seemed to be too small or too great for him. He invented an apparatus for taking books from high shelves. He suggested that sailors could mitigate thirst by sitting in the salt water or soaking their clothes in it. The pores of the skin, he said, while large enough to admit the water, are too small to allow the salt to penetrate; and the experiment was successfully tried by shipwrecked crews. He suggested that bread and flour could be preserved for years in air-tight bottles, and Captain Cook tried it with good results in his famous voyage. It is certainly strange that the man who was so passionately interested in such subjects should enter the great domain of constitution-making and, in spite of many blunders, excel those who had made it their special study.
He had no knowledge of technical law, either in practice or as a science. He was once elected a justice of the peace in Philadelphia, but soon resigned, because, as he said, he knew nothing of the rules of English common law. It was perhaps the only important domain of human knowledge in which he was not interested.
As a public man of long experience he had considerable knowledge of general laws and their practical effect. He was a law-maker rather than a law-interpreter. He understood colonial rights, and knew every phase of the controversy with Great Britain, and he had fixed opinions as to constitutional forms and principles. Some of his ideas on constitution-making were unsound; but it is astonishing what an important part he played during his long life in American constitutional development.
I have shown in another volume, called "The Evolution of the Constitution of the United States," how the principles and forms of that instrument were developed out of two hundred years' experience with more than forty colonial charters and Revolutionary constitutions and more than twenty plans of union. The plans of union were devised from time to time with the purpose of uniting the colonies under one general government. None of them was put into actual practice until the "Articles of Confederation" were adopted during the Revolution. But although unsuccessful in the sense that no union was formed under any of them, they contributed ideas and principles which finally produced the federalism of the national Constitution under which we now live.
