TO FOREIGN CORRESPONDENTS.
It Is due to our readers abroad to make them aware that we have been compelled to adopt the rule of not taking in unpaid letters or packets by foreign posts, from correspondents unknown to us. We have been obliged to adopt that rule in self-defence. Packets have come to us from all parts, East and West, sometimes containing matter of general Interest, oftener of purely local Interest, and sometimes of no interest at all : the expense In postage or carriage was considerable—in time, still mom vexatious. In the case of communications from unaccredited correspondents, there was no means of exercising any process of selection ; and we could only rind relief by excluding all of that class : all Such communications are returned to the postman or carrier unopened. In the mass, It La possible that there were some letters which merited our attention ; but the writers will now understand tlfe reason why we have not noticed them. To complete their wish to Inform us, correspondents should transmit their communications through some accre- dited channel in England.
