Such were the arguments to which Adams was obliged to listen. The popular feeling was so strong that Pitt could not have stemmed it if he would. It was in vain that Adams threatened reprisals, and urged that the British measures would defeat their own purpose. "The end of the Navigation Act," said he, "as expressed in its own preamble, is to confine the commerce of the colonies to the mother country; but now we are become independent states, instead of confining our trade to Great Britain, it will drive it to other countries:" and he suggested that the Americans might make a navigation act in their turn, admitting to American ports none but American-built ships, owned and commanded by Americans. But under the articles of confederation such a threat was idle, and the British government knew it to be so. Thirteen separate state governments could never be made to adopt any such measure in concert. The weakness of Congress had been fatally revealed in its inability to protect the loyalists or to enforce the payment of debts, and in its failure to raise a revenue for meeting its current expenses. A government thus slighted at home was naturally despised abroad. England neglected to send a minister to Philadelphia, and while Adams was treated politely, his arguments were unheeded. Whether in this behaviour Pitt's government was influenced or not by political as well as economical reasons, it was certain that a political purpose was entertained by the king and approved by many people. There was an intention of humiliating the Americans, and it was commonly said that under a sufficient weight of commercial distress the states would break up their feeble union, and come straggling back, one after another, to their old allegiance. The fiery spirit of Adams could ill brook this contemptuous treatment of the nation which he represented. Though he favoured very liberal commercial relations with the whole world, he could see no escape from the present difficulties save in systematic retaliation. "I should be sorry," he said, "to adopt a monopoly, but, driven to the necessity of it, I would not do things by halves.... If monopolies and exclusions are the only arms of defence against monopolies and exclusions, I would venture upon them without fear of offending Dean Tucker or the ghost of Dr. Quesnay." That is to say, certain commercial privileges must be withheld from Great Britain, in order to be offered to her in return for reciprocal privileges. It was a miserable policy to be forced to adopt, for such restrictions upon trade inevitably cut both ways. Like the non-importation agreement of 1768 and the embargo of 1808, such a policy was open to the objections familiarly urged against biting off one's own nose. It was injuring one's self in the hope of injuring somebody else. It was perpetuating in time of peace the obstacles to commerce generated by a state of war. In a certain sense, it was keeping up warfare by commercial instead of
