DIFFICULTY OF ROLLING THE AMERICAN RAIL.

Mr. Stevens received no favorable answer to his proposals, but being

acquainted with Mr. Guest (afterward Sir John Guest), a member of

Parliament, proprietor of large iron works in Dowlais, Wales, he

prevailed upon him to have rails rolled at his works. Mr. Guest became

interested in the matter and accompanied Mr. Stevens to Wales, where

the latter gave his personal supervision to the construction of the

rolls. After the rolls were completed the Messrs. Guest hesitated to

have them used, through fear of damage to the mill machinery, upon

hearing which Mr. Stevens deposited a handsome sum guaranteeing the

expense of repairing the mill in case it was damaged. The receipt for

this deposit was preserved for many years among the archives of the

Camden and Amboy Company. As a matter of fact, the rolling apparatus

did break down several times. "At first," as Mr. Stevens in a letter

to his father, which I have seen, described it, "the rails came from

the rolls twisted and as crooked as snakes," and he was greatly

discouraged. At last, however, the mill men acquired the art of

straightening the rail while it cooled.

The first shipment,[3] consisting of five hundred and fifty bars

eighteen feet long, thirty-six pounds to the yard, arrived in

Philadelphia on the ship Charlemagne, May 16, 1831.

Over thirty miles of this rail was laid before the summer of 1832.

A few years after, on much of the Stevens rail laid on the Camden and

Amboy Railroad, the rivets at the joints were discarded, and the bolt

with the screw thread and nut, similar to that now used, was adopted

as the standard.

The rail was first designed to weigh thirty-six pounds per yard, but

it was almost immediately increased in weight to between forty and

forty-two pounds, and rolled in lengths of sixteen feet. It was then

three and a half inches high, two and one-eighth inches wide on the

head and three and a half inches wide at the base, the price paid in

England being £8 per ton. The import duty was $1.85.

The first shipment of rail, having arrived in America, was transported

to Bordentown, and here, upon the ground on which we stand, and which

this monument is erected to mark forever, was laid the first piece of

track (about five-sixths of a mile long) in August, 1831. The Camden

and Amboy Company, following the example of the Manchester and

Liverpool Railroad, laid their first track upon stone blocks two feet

square and ten to thirteen inches deep. These blocks were purchased

from the prison authorities at Sing Sing, N.Y. Some of these stone

blocks have been used in constructing the foundation for this

monument.

This iron proved to be of such superior quality that after it was

worn out in the track, the company's mechanics preferred it to new

iron in making repairs. Some of this rail is still in use in side

tracks. It is pronounced equal in durability to much of the steel

rail of to-day. ]
