On this day 250 years ago in Cambridge, the Massachusetts Provincial Congress:

strongly recommended to the inhabitants of the towns and districts of this province, that, should any person or persons presume to supply the troops now stationed at Boston or elsewhere in said province, with . . . any . . . materials whatever, which may enable them to annoy, or in any manner distress said inhabitants, he or they so offending shall be held in the highest detestation, and deemed inveterate enemies to America, and ought to be prevented and opposed by all reasonable means whatever.
