Lightning-rods became the fashion, though there was great opposition, because many believed that lightning was one of the means of punishing the sins of mankind, and it was wrong to attempt to prevent the Almighty from doing his will. Some learned men urged that a ball instead of a point be used at the end of the rod, and George III. insisted that the president of the Royal Society should favor balls. "But, sire," said Sir John Pringle, "I cannot reverse the laws and operations of nature."
"Then, Sir John, you had perhaps better resign," was the reply, and the obstinate monarch put knobs on his conductors.
Through all the scientific discord, Franklin had the rare good-sense to remain quiet, instead of rushing into print. He said, "I have never entered into any controversy in defence of my philosophical opinions; I leave them to take their chance in the world. If they are right, truth and experience will support them; if wrong, they ought to be refuted and rejected. Disputes are apt to sour one's temper and disturb one's quiet."
Franklin was not long permitted to enjoy his life of study. This same year, 1752, he was elected a member of the Pennsylvania Assembly, and reëlected every year for ten years, "without," as he says, "ever asking any elector for his vote, or signifying, either directly or indirectly, any desire of being chosen." He was also, with Mr. William Hunter of Virginia, appointed postmaster-general for the colonies, having been the postmaster in Philadelphia for nearly sixteen years. So excellent was his judgment, and so conciliatory his manner, that he rarely made enemies, and accomplished much for his constituents. He cut down the rates of postage, advertised unclaimed letters, and showed his rare executive ability and tireless energy.
For many years the French and English had been quarrelling over their claims in the New World, till finally the "French and Indian War," or "Seven Years' War," as it was named in Europe, began. Delegates from the various colonies were sent to Albany to confer with the chiefs of the Six Nations about the defence of the country. Naturally, Franklin was one of the delegates. Before starting, he drew up a plan of union for the struggling Americans, and printed it in the Gazette, with the now well known wood-cut at the bottom; a snake cut into as many pieces as there were colonies, each piece having upon it the first letter of the name of a colony, and underneath the words, "Join or Die." He presented his plan of union to the delegates, who, after a long debate, unanimously adopted it, but it was rejected by some of the colonies because they thought it gave too much power to England, and the king rejected it because he said, "The Americans are trying to make a government of their own."
Franklin joined earnestly in the war, and commanded the forces in his own State, but was soon sent abroad by Pennsylvania, as her agent to bring some troublesome matters before royalty. He reached London, July 27, 1757, with his son William, no longer the friendless lad looking for a position in a printing-house, but the noted scientist, and representative of a rising nation. Members of the Royal Society hastened to congratulate him; the universities at Oxford and Edinburgh conferred degrees upon him. While he attended to matters of business in connection with his mission, he entertained his friends with his brilliant electrical experiments, and wrote for several magazines on politics and science.
After five years of successful labor, Doctor Franklin went back to Philadelphia to receive the public thanks of the Assembly, and a gift of fifteen thousand dollars for his services. His son was also appointed governor of New Jersey, by the Crown. Franklin was now fifty-seven, and had earned rest and the enjoyment of his honors. But he was to find little rest in the next twenty-five years.
The "Seven Years' War" had been terminated by the Treaty of Paris, February 10, 1763. Of course, great expenses had been incurred. The following year, Mr. Grenville, Prime Minister of England, proposed that a portion of the enormous debt be paid by America through the Stamp Act. The colonies had submitted already to much taxation without any representation in Parliament, and had many grievances. The manufacture of iron and steel had been forbidden. Heavy duties had been laid upon rum, sugar, and molasses, and constables had been authorized to search any place suspected of avoiding the duties.
When the Stamp Act was suggested, the colonies, already heavily in debt by the war, remonstrated in public meetings, and sent their protests to the king. Franklin, having been reappointed agent for Pennsylvania, used all possible effort to prevent its passage, but to no avail. The bill passed in March, 1765. By this act, deeds and conveyances were taxed from thirty-seven cents to one dollar and twenty-five cents apiece; college degrees, ten dollars; advertisements, fifty cents each, and other printed matter in proportion.
At once, the American heart rebelled. Bells were tolled, and flags hung at half-mast. In New York, the Stamp Act was carried about the streets, with a placard, "The folly of England and the ruin of America." The people resolved to wear no cloth of English manufacture. Agents appointed to collect the hated tax were in peril of their lives. Patrick Henry electrified his country by the well known words, "Cæsar had his Brutus, Charles I. had his Cromwell, and George III."—and when the loyalists shouted, "Treason!" he continued, "may profit by their example. If that be treason, make the most of it."
