A MONTH IN NORTH CORNWALL 29] 
41 Diurni, 36 Nocturni, 3 Drepanulide, 11 Pseudo-Bombyces, 
132 Noctuz, and 112 Geometre, and I have no doubt this list 
would be largely increased if the country round were thoroughly 
and systematically worked.

A MONTH IN NORTH CORNWALL. 
By W. 8. Ripine, M.D., B.A. 
TrEvALGA, Where I was staying last September, is situated 
on the north coast of Cornwall, between Boscastle and Tintagel. 
It is elevated some 200 feet above sea-level, and backed a short 
distance inland by hills rising 700 or 800 feet. Like the rest of 
the county, it would be treeless were it not for the wooded valleys 
trending seawards. ‘The chief of these are that at Boscastle, 
where the Vallency runs over a rocky bed between overhanging 
alders and willows, with a sprinkling here and there of ash and 
oak, and that at St. Knighton’s Kieve, on the west, where a 
nameless stream falls in a cascade of 40 feet, and winds its 
course through a pretty glen wooded with beech and ash, larch 
and pine, to the Rocky Valley, known well to every landscape- 
painter since Creswick’s time. Both valleys are luxuriantly 
clothed with the usual plants of such localities, hemp-agrimony 
and golden-rod being especially abundant. One point of interest 
to the entomologist is the unusual growth of ivy, creeping over 
cottages and outhouses, covering ruined walls, on boulders of 
rock, and somewhere in most of the hedges. The lover of ferns, 
too, can find most of our native species, and amongst them 
Osmunda regalis in fair abundance, Hymenophyllum tunbridgense, 
and, if he does not mind wet feet and soiled clothes, Aspleniwm 
marinum in the shaded crannies of the rocks ; and, with the help 
of a scaling-ladder, Adiantum capillus-veneris growing wild on the 
cliffs. ‘The geological formation is Devonian slate and schist, 
the Devonian system being overlapped by the Carboniferous 
between Trevalga and Boscastle. Fyrom the stratifications being 
unequally acted on by denuding influences, the exposed rocks 
look like fretted and chiselled ruins of ancient castles, which the 
imagination can easily associate with the legends of the 
neighbourhood.
