82 A NEW FLORA 01' 



The lower part of the vale of the Aln is not more than from 

 2 to 4 miles wide. The most interesting botanical station near 

 Alnwick is Eatcheugh Crag, another portion of the basaltic dike 

 which from this point runs across the county in a south-western 

 direction. Here occur Sesleria ccerulea, Astragalus glycyphjllos 

 and hypoglottis^ Geranium sanguineum, Bianthus deltoides, Ifcen- 

 cMa erecta, and several other interestiag species. The area of 

 this district is about 150 sq^uare mUes. IS'one of the hills, except 

 those west of Alnham, rise distinctly into the Middle zone.

4. COQUET DISTEICT. 



The course of the Coquet is nearly in a line from west to east, 

 and its length about 40 miles. For several miles its watershed 

 ridge on the north forms the boundary between England and 

 Scotland. The upper part of the dale has entirely the charac- 

 teristic Cheviot aspect — a narrow grassy hollow, with a stony 

 unenclosed moorland road, at the bottom a brawling mountain 

 streamlet, excellent for trout-fishing, grassy hills rising steeply 

 from this on either bank, very little actual crag, and what there 

 is usually down by the stream-side, but often great sweeps of 

 porphyritic debris stretching down the banks, flecked with green 

 of brake and purple of foxglove. At the corner, between the 

 TJsway Burn and the Breamish, Windygyle is quite 2000 feet 

 in altitude, and between the Alwine and Hedgehope, Cushat Law 

 and Weather Cairn reach 2019 and 1836 feet. Erom this point

 the river is not so high. Between the two forks of the Coquet,
