There are pieces of black lime-flate 

 fcattered on thole hills, which confift of

 miles along the fide of the river, there is 

 not a piece of lime-flate to be feen ; but 

 inftead of it, there are high grey moun- 

 tains, confiding of a rock-ftone, which

 mixed with lime-flone, and black glim-

 into the vv^ater. We now begin to fee the 

 lime-flates again.

The river is here computed at about

On the fides of the river, about two 

 French miles inbnd, there are fuch terraces 

 of earth as at 'Terre iEbouiement j but foon

Several brooks fall into the river here, 

 over the fteep fhores, with a great noife. 

 The fhores are fometimes feveral yards-
