Our necessitiea compol ua to announce ro p'Ã¯r pntrons, that nfter three weeks we shall erase from our list those who are indebted to U8 for the Signal for one year or more. An unreasonable extensiÃ³n of credit hns been tlie fatol rock on which thousnnds of papers have pcrished; and this is the only course by which it can be avoided. We $hal! forward bilis to them, and should errors bp discovered, they will be cheerfully corrected. Wc should be happy to furnish our friends with a Liberty paper on any .lenglh of credit they might wish; bul we ennnot extend the time beyond a year, without involving oursel vea bevond our resources. Should the paper be slopped, to ony who wish to continue it, we hope they will renew thuir eubseription on the terms of the paper, and thua benefit themselves, and holp our cause.
