APPENDIX, 



is much the mofl convenient inftrument that can bo carried, or nfed in the 

 woods ; the cxpence of running lines any other v/ay, would be too great 

 for individuals to bear ; and the furvcyors are not qualified to run them by 

 the true naeridian. For fucli reafons it is probable thai, the Magnetic Nee- 

 clle will fliil continue to be the indrument, by which the lir>es will be run, 

 and the townftiips be laid o'Jt in America. VVe muft therefore en- 

 deavor to provide the beft remedy we can, for an error or evil, which we 

 cannot eafily remove. The beii remedy which the cafe admits of, is an ac- 

 curate ob'eivation ef the variation of the Magnetic Need ie, at the time when 

 divifional lines are tun. This fhou'd be done b>' able mathematicians, and 

 in as many placsina Hate, as may be. Such obfervations will afford the 

 beff diredtioii, lufveyois will be able to find, to enable them to determine 

 what is the real or true direction of their Magnetic lines. — It is with thjj 

 view, that the folio./ ing Table is fubjoined.
