Jan 1830

Mr. Baldwin (son of the contractor) gave me a sketch of a bridge built entirely of plank, invented by a Mr. Town; - there are several bridges built upon this plan in the U.S. & Mr. Baldwin is now building one over the Susquehanna River a few miles from Harrisburgh where the Pennsylvania canal crosses it. Went to Shippingport with Mr. D. Carrol & took the dimension of the locks. Found the guard lock (between h.c.) 203 5m
Upper lock: 199.11m
Middle Lock: 199.6
Lower Lock: 195.10

...Ivesburgh* to see Mr. Baldwin who gave me the [illegible] of his roll of drawings. I find they relate mostly to the Delaware & Hudson Canal & the railroad at its western end called the Carbondale railroad.

It was suggested to me today by May Allen that a railroad eompany might be formed to construct a road from this place to Portland & said that if the canal co. did not do justice to the contractors he would punish them using his influence to have a railroad formed by the side of their canal which would rob it of most of its business. I had before heard the subject mentioned & had payed some attention to it & had written an article on the same subject.
*The place where the contractors by that name has his office has been called Ivesburgh [illegible] the bridge]
