Cross-examined--When the bridge was first put up, it settled, and
I made the remark that if it kept on, it would go into the creek;
perhaps I told it to half a dozen others; said it was not Mr.
Collins’ bridge, but Mr. Stone’s; said the bridge had cost a great
deal of money, but don’t recollect saying it would cost the company
a great deal more; was discouraged because the bridge acted so, and
that I couldn’t see how to remedy it; remember all this was before
the modifications were made; Mr. Congdon was with Mr. Stone when
the bridge was examined; the plan of changing the braces was then
adopted.
Mr. Albert Congdon, testified as follows: At the time of the
construction of this bridge I was employed by the Lake Shore Road
as master machinist; knew something about the construction of this
bridge, as I had charge of the work in making the bridge; found a
lack of material to fill the place for which it was designed; told
Mr. Thompson about it, and he wanted to know if he had better let
Mr. Stone know it; told him he had better; a short time afterward
I was told to take the plans and finish the construction of the
bridge as I thought it should be done; do not know how far the work
had progressed at the time I assumed control; the braces were not
marked so as to designate the position they were to occupy; never
calculated the strength of the tension of compression members; did
not say much to Mr. Tomlinson or any other man about the bridge,
as I did not consider myself a competent bridge man; from the time
of Mr. Tomlinson leaving, I had the management of constructing the
bridge; Mr. Rogers told me that Mr. Stone had given him orders to
erect it, but he did not know how; I asked him why he did not go
and tell Mr. Stone so, and he said that he did not like to; I then
told him as much as I knew.
Testimony of the man who drew the plans for the Ashtabula bridge.
Joseph Tomlinson is sworn. Resides in Ottawa, Ont. Is General
Superintendent of Lighthouses in the employ of the Canadian
Government. Was engaged in bridge-building from 1840 to 1870. He
made the drawings for the iron Howe truss bridge over Ashtabula
Creek--the one which had lately fallen. He did this under
instructions from Mr. Stone. He never approved of a wrought-iron
Howe truss over a large span. It makes an unnecessarily heavy
bridge, and all the strain accumulates at the end braces.
Notwithstanding its weight, it would have been a strong, durable
bridge had the main braces been sufficiently strong. They were
not made as large as designed, and it was his intention that they
should be strengthened, but his connection with the Company was
severed on account of a difference that arose between himself and
Mr. Stone concerning the bridge.
