Through the Vale of Pickering the course of the Derwent is 

 almost due west. At the point where it turns in a western 

 direction, a small stream joins it from the east, which is called 

 the Hertford river, and which rises not far from the coast near 

 Filey, and flows for about five miles through low marshy ground 

 down the hollow between the Chalk and the Limestone. West 

 of Forge Valley are three small wooded glens in the limestone 

 range, which are called Yedmandale, Bee Dale, and Sawdon Dale. 

 The next dale to the main dale of Derwent which penetrates 

 through the southern to the northern range of hills is called 

 Newton Dale. The head of this dale joins the head of Goathland 

 Dale, and the Whitby and Pickering railway runs along the 

 depression which is thus obtained, from Pickering up Newton 

 Dale, over the watershed ridge, which at this point is under 200 



Jan. 1889.
