On this day 250 years ago, the Boston Committee of Correspondence under the pen of Sam Adams wrote to the Marblehead Committee of Correspondence that

We have receivd a Letter from New York dated the Day before the Post came out from that City, advising us that there was to be a meeting of the merchants there on the Tuesday following (last Tuesday)–that by a Vessel which had arrivd there from London the Citizens had receivd the barbarous Act with Indignation–that no Language could express their Abhorrence of this additional Act of Tyranny to all America–that they were fully perswaded that America was attackd & intended to be enslavd by their distressing & subduing Boston–that a Compliance with the provision of the Act will only be a temporary Reliefe from a particular Evil, which must end in a general Calamity–that many timid People in that City who have interrested themselves but very little in the Controversy with Great Britain express the greatest resentment at the Conduct of the Ministry to this Town and consider the Treatment as if done to them–and that this is the general Sense of the Inhabitants– that it was the general Talk that at the Meeting of the Merchants it would be agreed to suspend commercial Connection with Great Britain– . . . and we are to be advisd of the Result of the meeting, which we expect very soon. The Express which we sent to New York had not arrivd when this left the City.

When the letter from the New York Committee of Correspondence was subsequently delivered in Boston by the Express rider (Paul Revere), Adams would learn that the “Letter from New York dated the Day before the Post” was too optimistic in predicting that New York would join Boston in boycotting British goods. Adams did note that towns in other New England colonies were supporting Massachusetts’ call for non-importation:

We have receivd Letters by the post from Portsmt in New Hampshire, from Hartford Newport Providence Westerly &c. all expressing the same Indignation and a Determination to joyn in like measures–restrictions on their Trade.
