To the best of our knowledge the drawings are not in any public record office and they complement material presented by the Rennie family some years ago. We have both John and Sir John Rennie’s report books including one volume specifically relating to the Lancaster Canal. We also have a volume of specifications relating to the canal. Although we have a number of prints of engineering works which belonged to the family there are only a few drawings and no original drawings of his canal schemes. It is ICE policy to collect drawings representative of the full range of works carried out by the profession historically.
The drawings show proposed structures to be built on the canal and are dated 1794. They are all signed by Rennie and the contractor.
