Thb Northern Vergr. The Wes¬ 
tern Spy, received on Tuesday, is accom¬ 
panied by a Supplementary Sheet, con¬ 
taining a map or delineation ol the Nor¬ 
thern'Verge of the globe. The impres¬ 
sion is from a wooden block, cut with a 
penknife, by Capt. John Cleves Symmes, 
who presents it, he says, ‘‘rather as an «.X' 
position of the constituent principles ol 
his theory of the earth, than as a codec* 
tion of proofs of its truth.” He has a Iso 
given an elaborate explanation of the map, 
occupying about four closely printed col¬ 
umns. Capt. Symmes may be laugned 
at as a visionary, or pitied as a lunatic,^ 
but it seems he is not to be flouted out o 
his theory by “squibs and crackers,” nor 
will he fail of accomplishing his purpose 
by want of perseverance.
