When Franklin heard this, his countenance was as placid and unmoved as it had been under the hailstorm of Wedderburn's vituperation.
In March, 1775, Franklin left England for America to confer with the Continental Congress. During his ten years sojourn in England, he had by no means been entirely absorbed by public affairs. The versatility of this model Yankee had been as wonderful as ever. While zealously advocating the cause of the colonies he had at the same time thought and written on such things as the introduction of silk culture in America; he had worked to promote Captain Cook's philanthropic expedition to the Pacific islands; he had drawn up a plan for a new system of spelling; made valuable studies and experiments in ventilation; inquired largely and ingeniously into the cause of colds; discussed in his letters such things as the average fall of rain; chimneys; fireproof stairs; metallic roofs; the Northwest passage; spots on the sun; the glass-harmonica; improved carriage wheels; glass blowing; the torpedo; the Aurora Borealis; inflammatory gases; Prince Rupert's drops; the effects of vegetation on air and water; smoke-consuming stoves; the effect of oil on the sea in storms; the relative force required to pull boats over shallow and over deep water; pointed or blunt lightning-rods; and points of political economy discussed with Adam Smith. If anything had escaped his observation, it must have been far out of his way.
When he arrived at Philadelphia, he found his country in open revolt against Great Britain. His keen eye had, much earlier than others, foreseen that a separation of the colonies from the mother country was likely to come. Still he had worked to avert it, faithfully, though without much hope. When it came it was to him neither unexpected nor unwelcome. Now the struggle had begun. The Continental Congress governed the United Colonies.
