The remaining portion of the district belongs to the Central 

 Valley. The stream is the boundary of the Riding and the 

 tract which it drains on the north varies from two to four miles 

 in width. The city of Ripon stands upon the edge of the Mag- 

 nesian Limestone not far from the river immediately opposite 

 the part we have now reached. Hutton Moor was once a tract 

 of low sandy heatherland but it is now cut through by the rail- 

 way and almost entirely enclosed. The following are the rarer

 Hutton Conyers :
