lime-stone to draw-kills, which he has cut out of a spongy- 

 rock, on the edge of a den close by his coal-pits. This ca- 

 nal is on a level with the top of his draw-kills. From the 

 bottom of these kills another canal is cut, extending north- 

 ward about half a mile, till it reach the declivity of the hill, 

 for the purpose of carrying away the burnt lime-stone, as 

 also coal, and some other articles to be mentioned after- 

 wards. When the loaded boats reach the end of this canal, 

 they are made to pass into skeleton carriages having broad 

 wheels, and conveyed down the hill, to the side of the high 

 way, near the village of Kettle, where their contents are 

 to be deposited in shades for the convenience of purchasers. 

 In passing down the hill they go singly, and are drawn up, 

 when empty, by horses. But it is intended that after the 

 first year the loaded carriages shall draw up the empty 

 ones. The same method is observed in bringing the un- 

 burnt lime-stone from the quarry to the entrance of the 

 upper canal. 



Neither of these canals have occasion for locks, as they 

 are on a dead level. Both branches are of the same dimen- 

 sions, being nine or ten feet broad, and three feet deep. 

 They are supplied with water from a coal-level, which ne- 

 ver becomes dry ; and all surface water is excluded, to pre- 

 vent the canals being filled up with the mud, which such 

 water may occasionally bring along with it. 



The boats on the different canals are not of the same size. 

 Those on .the upper canal, being used only for carrying raw 

 lime-stone/ afe to be from four to ten tons burden ; where- 

 as the boats on the other are to contain two tons only. His 

 reason for making these, last 3<>,srmall is, that he wishes the 

 coal and lime conveyed, b^y them not to be broken, but to be 

 delivered at tbe slides- & entire as when taken from the 

 pits and the kiUs,* To make tljtse boats strong and tight, 

 the seams are to be covered wftlf t^ sheet iron or copper, 

 of two inches in breadth. r 



The conveyance of the boats along the lower canal, is 

 fo be effected by means of the boatman's pulling or shov-
