THE THAMES AND MFDWAY.
The grand union between the River Thames and Medway will be effected very shortly, by means of the largest tunnel, we believe, in the world. This giant public undertaking commences immediately, from the Port of London, below Gravesend, where there is a large river lock capable of admitting vessels ol 200 tons into a capsicious basin, with commodious wharfage. The canal, which is fifty feet wide, and seven feet deep in water, passes through the marsh lands to the vilage of Higham, a distance of nearly five miles, where the tunnel begins, which is twenty-two feet wide on the water level, and eight feet deep at spring tides, twenty-four feet six inches high from the water surface to the apex of the arch, with a towing pith five feet wide, firmly protected by means of a cast-iron and timber railing. Ihe tunnel continues under the chalk hills for a distance of upwards of two miles, where it terminates in a very large basin, commanded by a lock entering into the River Medway. and capable of receiving vessels of 300 tons. The whole length of this canal, from the River Thames to the Medwav. is only 7 1/4 miles ;
and by this very short line all the circuitous, tedious, and often times, dangerous passage round the Nore is avoided, thereby saving a distance of at least forty lo fifiy miles Thus the communication from the interior of Kent wish the North of England is made easy, safe, and at a comparatively trifling expence, with the advantage of a more certain passage, as well as a considerable saving on wear and tear of sails and tackle, &c. This important line also opens a communication from Tonbridge by means of the Regent's and Grand Junction Canals to Branstone in Northamptonshire, for the same sized craft, without any transhipment of goods, which may be forwarded to any ol the Northern parts of England. Craft from seven to eighteen feet beam can navigate the whole line, which it is obvious will secure to inland commerce incalculable advantages
