 Teith river, ten feet broad, and betwixt thir-

 infide of the rim of the wheel, that difcharges 

 forty tuns of water in one minute, into a 

 wooden ciftern at the top ; from which wood-

 the water about fifteen hundred yards, where 

 it runs into a canal, which condudls it to 

 different parts of the mofs, to carry it away.

 all made of foreign wood three inches thick, 

 bound with iron hoops within a few yards 

 of one another. The mofs is of a light Ipun-
