218 MISCELLANEA. 



situated in a wooded hollow, on the banks of the Wansbeck, 

 about seven miles from its estuary; and it still retains, amid the 

 hurry and change of naodem times, some aspect of old English 

 gentility. Erom Morpeth the ground rises north-west, through 

 a sparsely populated district, where the furze, the honeysuckle, 

 and wild rose still haunt the lanes and hedgerows, until the 

 Cheviots loom into view, a promising region for the lichenologist 

 when it may be searched. On the day referred to, we had to 

 content ourselves with a ramble between Mitford and Morpeth, 

 and the following list comprises the lichens we gathered. It is 

 only fair to say, that our day was not the most favourable. The 

 ground was damp and slippery on the banks, consequently our 

 search wa,s neither very close nor protracted. The smoke from 

 the Tyne and the Northumberland coal-field seems to have some- 

 what affected the lichenoid growth of this locality, which it will 

 eventually obliterate. Already the deleterious atmosphere from 

 the Tyneside has utterly destroyed species of Ramalina, which 

 flourished in fruitfulness, on the trees about Gibside, in the days 

 of Mr. "Winch. Tor verification of this, vide Science Gossip,
