Aberdeen Harbour Board: Letter from Alexander Jopp, Aberdeen Letter to Mr. Riddel, Harbour Office: "Dear Sir, I have received your letter of the 9 and shall, in consequence, desire the contractor for the Tide Lock to see Mr. Joseph (?), upon the subject; and I have no doubt they will be able to arrange to the mutual convenience of bo parties- you need not therefore, trouble the Trustees in the matter, in the meantime should difficulty, which I do not anticipate, occur, then it will be time enough to bring the subject under the consideration of the Harbour Trustees. I am dear Sir, yours very truly, Alexander Jopp." 11 November 1833
