100 WHERE TO FIND FERNS. 



on basaltic rocks in the neighbourhood of Cauldron 

 Snout and on Falcon Glints, Teesdale. In Wales, in the 

 counties of Caernarvon and Merioneth ; in Caernarvon- 

 shire, at the pass of Llanberis amongst limestone rocks : 

 also on rocks at Clogwyn-y-Garnedd and in similar 

 positions at the little Dog's Lake (Llyn-y-Cwm) near 

 Glyder Vawr. Here the plants have been reputed to be 

 abundant, but difficult of access, owing to the steepness 

 of the rocks. In Scotland, in the counties of Dumfries, 

 Elgin, Forfar, and Perth ; and in the following localities 

 in those counties : in Dumfries, at the " Devil's Beef- 

 tub," upon rocks in a ravine near Loch Skene, at a farm 

 called Corehead near Moffatt, and upon hills near 

 Moffatt; also amongst crumbling rocks upon hills divid- 

 ing Dumfries from Peebles ; in Elgin, near Forres ; in 

 Forfar, in Glen Fiadh amongst the Clova Mountains. 

 It is also found on rocks upon Ben Chonzie, near Crieff, 

 and its other habitats in Perthshire are on Ben Lawers. 

 It has not been recorded as having been found in 

 Ireland : but it is quite possibly present in many localities, 

 where it has not been discovered by botanists who are 

 in the habit of publishing their " finds."
