The copy is in Nimmo’s own hand, written up in the form of a journal, from the notes which he took in his pocket-book whilst engaged upon the survey. It is written on the rectos of the leaves, the versos being left for maps (folios 11 verso, 12 verso), notes, bearings, and additions to the text. It appears to be incomplete, for it ends rather abruptly (folio 50). It is followed by an explanatory letter to John Rickman, who at the time was secretary to the commissions for making roads and bridges in Scotland.
