As early as October, 1767, the Boston merchants entered into such an agreement, which was however not very drastic and proved to be of no effect, as it was at first unsupported by the merchants in any other colony. In April, 1768, the merchants of New York, seeing the necessity of concerted action, agreed not to import "any goods [save a very few enumerated articles] which shall be shipped from Great Britain after the first of October next; provided Boston and Philadelphia adopt similar measures by the first of June." Philadelphia merchants said they were not opposed to the principle of non-importation, but greatly feared the New York plan would serve to create a monopoly by enabling men of means to lay in a large stock of goods before the agreement went into effect. This was very true; but the objection, if it was an objection, proved not to be an insurmountable one. Before the year was out, in the late summer for the most part, the merchants in all the commercial towns had subscribed to agreements, differing somewhat in detail, of which the substance was that they would neither import from Great Britain any commodities, nor buy or sell any which might inadvertently find their way in, until the duties imposed by the Townshend act should have been repealed. The merchants' agreements were, for whatever reason, much better observed in some places than in others. Imports from Great Britain to New York fell during the year 1769 from about £482,000 to about £74,000. Imports into New England and into Pennsylvania declined a little more than one half; whereas in the southern colonies there was no decline at all, but on the contrary an increase, slight in the case of Maryland and Virginia and rather marked in the Carolinas. In spite of these defections, the experiment was not without effect upon English merchants. English merchants, but little interested in the decline or increase of trade to particular colonies, were chiefly aware that the total exportation to America was nearly a million pounds less in 1769 than in 1768. Understanding little about colonial rights, but knowing only, as in 1766, that their "trade was hurt," they accordingly applied once more to Parliament for relief. The commerce with America which was "so essential to afford employment and subsistence to the manufactures of these kingdoms, to augment the public revenue, to serve as a nursery for seamen, and to increase our navigation and maritime strength"--this commerce, said the Merchants and Traders of the City of London Trading to America, "is at present in an alarming state of suspension"; and the Merchants and Traders of the City of London therefore humbly prayed Parliament to repeal the duties which were the occasion of their inconveniences.
