The events of the last twelve months had gone further than anything before toward awakening a sentiment of union among the people of the colonies. It was still a feeble sentiment, but it was strong enough to make them all feel that Boston was suffering in the common cause. The system of corresponding committees now ripened into the Continental Congress, which held its first meeting at Philadelphia in September, 1774. Among the delegates were Samuel and John Adams, Robert Livingston, John Rutledge, John Dickinson, Samuel Chase, Edmund Pendleton, Richard Henry Lee, Patrick Henry, and George Washington. Their action was cautious and conservative. They confined themselves for the present to trying the effect of a candid statement of grievances, and drew up a Declaration of Rights and other papers, which were pronounced by Lord Chatham unsurpassed for ability in any age or country. In Parliament, however, the king's friends were becoming all-powerful, and the only effect produced by these papers was to goad them toward further attempts at coercion. Massachusetts was declared to be in a state of rebellion, as in truth she was. [Sidenote: The Suffolk Resolves, Sept. 1774.] While Samuel Adams was at Philadelphia, the lead in Boston was taken by his friend Dr. Warren. In a county convention held at Milton in September, Dr. Warren drew up a series of resolves which fairly set on foot the Revolution. They declared that the Regulating Act was null and void, and that a king who violates the chartered rights of his subjects forfeits their allegiance; they directed the collectors of taxes to refuse to pay the money collected to Gage's treasurer; and they threatened retaliation in case Gage should venture to arrest any one for political reasons. These bold resolves were adopted by the convention and sanctioned by the Continental Congress. Next month the people of Massachusetts formed a provisional government, and began organizing a militia and collecting military stores at Concord and other inland towns.
