colonies, without restraint, and of carrying on trade from one colony to another, under the regulation of the general laws of the empire, without restriction by colonial legislation. They had, moreover, common grievances to be redressed, and a common independence to establish, if redress could not be obtained: for although the precise grounds of dispute with the Crown or the Parliament of England had not always been the same in all the colonies, yet when the Revolution actually broke out, they all stood in the same attitude of resistance to the same oppressor, making common cause with each other, and resting upon certain great principles of liberty, which had been violated with regard to many of them, and with the further violation of which all were threatened. * * * * * It was while the controversies between the mother country and the colonies were drawing towards a crisis, that Dr. Franklin, then in England as the political agent of Pennsylvania, of Massachusetts, and of Georgia, in an official letter to the Massachusetts Assembly, dated July 7th, 1773, recommended the assembling of a general congress of all the colonies. "As the strength of an empire," said he, "depends not only on the _union_ of its parts, but on their readiness for united exertion of their common force; and as the discussion of rights may seem unseasonable in the commencement of actual war, and the delay it might occasion be prejudicial to the common welfare; as likewise the refusal of one or a few colonies would not be so much regarded, if the others granted liberally, which perhaps by various artifices and motives they might be prevailed on to do; and as this want of concert would defeat the expectation of general redress, that might otherwise be justly formed; perhaps it would be best and fairest for the colonies, in a general congress now in peace to be assembled, or by means of the correspondence lately proposed, after a full and solemn assertion and declaration of their rights, to engage firmly with each other, that they will never grant aids to the crown in any general war, till those rights are recognized by the King and both houses of Parliament; communicating at the same time to the crown this their resolution. Such a step I imagine will bring the dispute to a crisis."[4]
