[CB] It is from 65 to 75 feet wide at top, and 7 feet deep. The locks are well constructed, and very expeditiously worked.
[CC] [The link between New Brunswick and Trenton has since been authorised by the State and constructed.—Transl.]
[CD] [The Baltimore and Philadelphia, Fredericksburg and Roanoke, and Portsmouth and Roanoke railroads have since been completed.—Transl.]
[CE] It will be easy to construct a branch from the Charleston and Augusta railroad to Columbia, and the route has been surveyed. [This branch is now in progress, and as the Raleigh and Gaston railroad, from the Roanoke to Raleigh, is also nearly completed, there remains only the link between Raleigh and Columbia not yet undertaken.—Transl.]
[CF] [A prolongation of the Georgia railroad to Decatur, 160 miles from Augusta, is already in progress, and the Montgomery and Chattahoochee railroad, extending from West Point on the latter to the river Alabama, forms another link in the chain between Boston or rather Bangor and New Orleans.—Transl.]
[CG] During the session of 1836 the legislature of Massachusetts subscribed 1,000,000 in aid of the Western Railroad; this measure was the first step taken by the State in the promotion of public works, and indicates a complete revolution in its policy on this point. [This act was immediately followed by similar acts in aid of the several other railroads now in progress in the State, and in 1838, by a further grant of the credit of the State to the Western Railroad to the amount of 1,200,000 dollars. That work will be completed to Springfield in October (1839), and the section between Springfield and West Stockbridge is already far advanced towards its completion. The Lowell railroad has been extended to Nashua, and an eastern branch is now completed to Haverhill, of which a continuation towards Exeter is now in progress.—Transl.]
[CH] [To these should be added the railroads from Newark to Morristown, and from Elizabethtown to Somerville, both intersecting the New Brunswick railroad, and extending into a fine farming country. The Brooklyn railroad has also been continued about 20 miles beyond Jamaica.—Transl.]
[CI] On some of the canals the locks are partly of wood and partly of stone; these composite locks are economical and easily kept in repair, and deserve to be introduced in other countries. On many canals the locks are wholly of wood.
[CJ] The bridge over the Schuylkill at Philadelphia consists of a single arch of 300 feet span. [This beautiful structure has lately been destroyed by fire.—Transl.]
[CK] At this very time, Mr Wright, in spite of his 60 years, is directing in person the Harlæm railroad, the great New York and Erie road, the great work of connecting the James and Kanawha, by a railroad and canal, the works going on along the St. Lawrence in Upper Canada, 750 miles further north, and the railway from Havana to Guines in the islands of Cuba. The aggregate length of all these works is 870 miles. The most eminent engineers have always several works under their direction at once; it is understood, of course, that they are aided by skilful and intelligent assistants, who do most of the work.
