I picked up this 1814 cover to start filling in my rate gaps in my collection, with a Sterling Mileage mark 45 ---"E" , I think it is an E for Edinburgh.
The 7 1.2 postage matches the 45 miles to it destination.

I must be having a bad day today as i cant make out this handwriting to find out the destination of this letter. There are no marks on the back at all.
Mr R.... M,,,,,
What looks like Chartist but I don't think that is a town as I don't find one so I think it is his occupation.
By North ...... Ferry

Any help would be appreciated.

I read it as "Charleston, by North Queens Ferry". From Google it seems these are both villages in Scotland, and near to each other (the former now spelt "Charlestown").

Thank you so much. I could not make that out at all
