Con. — 11 set of detailed drawings will be supplied to the Con- tractor, which ho pledges himself to exactly follow, 80 that the various parts may be interchangeable not only with those engines ho may build, but also with existing G. T. R. engines. Where the dimensions are omited in this specifi- cation they will be found fully detailed in the draw, ings, and in the drawings the figured dimensions are to be preferred to scale. While the foregoing specification sets forth the general details of the Engines and Tenders, the G. T. Ry. Co. reserve the option of such modifi- cations as they may find necessary wnen completing the detail and working drawings, so long as the general principle and leading dimensions are not interfered with, without any claim for extra pay- ment being allowed. The Contractor will not be allowed to deviate from this specification and the attached drawings without the permission in writing of the Chief Mechanical Superintendent of the Grand Trunk Railway.
