From the Greta eastward to the district boundary is a tract 

 of undulated low country, with a good deal of wood and 

 generally a strong clayey soil, which altogether occupies some- 

 thing under a quarter of the whole district. It has no town in 

 it or village of any considerable size and does not anywhere 

 exceed five miles in breadth from north to south. A little 

 stream which rises in the low country not far from the Greta 

 flows due east and enters the Tees at Croft. The limestone 

 sweeps obscurely round the upper part of its hollow and the 

 remainder of the surface is mainly occupied, on the west by the 

 Millstone Grit, and on the east by the New Red Sandstone. 

 At Piercebridge the Magnesian Limestone, which comes out 

 in strong force upon the north of the river, just shews itself 

 in a cliff by the Tees side. Here grow Anemone Pulsatilla^ 

 Helleborus viridis, Sambucus Ebulus and Stachys anibigua. 

 From Piercebridge to Croft an embankment sweeps along by 

 the river side, sometimes coming up to the water's edge and 

 sometimes retreating from it for a short space, upon which, 

 where it is dry and sandy, grow Rosa Sabini, Scabiosa columbaria^ 

 Ficris hieiacioides and Origanum vulgare. At a distance of about 

 a mile from the Tees at Stapleton is situate upon the Durham 

 side of the river the town of Darlington. By the side of the Tees 

 in the Central Valley Scirpus pauciflorus and Stellaria ?iemorum 

 occur, and there is abundance of Myrrhis odorata, and some of 

 the Montane rarities which grow about the upper part of the 

 river, as for instance Gcntiana verna, Galium boreale and Plan- 



August 1888.
