INLAND NAVIGATION.

Wilden, and they will send no other goods along it but what are forexportation, and, as I said before, will turn out little to the income ofthe canal, being great in quality, but not in quantity; nor will it be aconstant trade, only once or twice a year, when the merchant ships areready for their voyage at Hull, as the manufacturer will send the pro-duce of a whole year’s work at once; nay, perhaps in so little compassas a small arms-chest, which may contain in nice polished ware six orseven thousand pounds worth, and perhaps would not pay to the ton-nage of the canal above six shillings for the thirty miles upon it, as thegoods at the utmost may not weigh above four tons.

" I must here take notice how easy the canal between Tern-bridgeand Batchacre Grange to Bridgeford will be completed, as no countrycan be more properly adapted for a navigation, being so well suppliedwith water, and a little below Batchacre Grange there is eight miles,and only eleven feet fall; so that there will be eight miles without alock. As I have mentioned some few words about the size of theboats necessary for this canal, I must give some description of the sizeof the locks, the quantity of water they receive and discharge, and thenshew the quantity of water in the reservoirs, and where those reservoirsare to be made, and how many boats that quantity of water will sufferto go through each lock in a day. The canal is proposed to be nineyards broad at the surface of the water, six yards broad at the bottom,and five feet deep in water: the sides will be an angle of about forty-five degrees. The boats are to be fifty feet long, and twelve feetbroad, and will carry thirty tons, and will draw three feet water loaded,with one mast to lower down upon deck, a main-sail, fore-sail, and jib,and a spare square-sail to hoist up before the wind : decked from stemto stern, or as occasion may require. One horse will draw these vesselsat the rate of five or six miles an hour, and they will bear the tides wayeither to Bristol, Liverpool, or Hull, which saves them the trouble ofre-shipping.
