ON THE SURRY CANAL. To the Editor of the Commercial and Agricultural Magazine. MR. EDITOR, London, Fune 17th, 1800.

YF AVING obſerved in a former part of your publication, H a plan by Mr. Dodd, of what is there called, the Grand Surry Canal, it was natural to attempt to obtain more complete information‘on the ſubje& of Canals, as an opening of new ſources of wealth and proſperity to this vaſt Metropolis. In the peruſal of authors who have publiſhed on this ſubject, it was impoſible not to be fruck with the evident propriety‘of theſe commercial conveniences, and fill more with wonder, at the effeétual‘oppoſition which intereſted individuals have always found means to create in the legiflature againſt this national im- provement.‘There is ſcarcely a third-rate town in England, which has not(more or leſs dire&ly) foreſeen and experienced the benefits of water-carriage.‘London owes her exiſtence to the navigation of the‘Thames, and yet has never made the eaſy tranſition of ideas, that canal-navigation muſt augment her com- merce more than the creation of another‘Thames, as a canal would convey commodities at a much lower expence than is in- curred by the frequent ſhoals,' and land-floods of the river.

From the date of canals in England(about the year 1760) London has been rapidly increaſing her trade and population, and thence has been the leſs eáger to eſtabliſh new facilities of internal commerce.
