94 : BRITISH FERNS. 
Scar. In Cumberland, at Glencoin, Blowike and 
near Ulswater and Keswick, In Westmoreland, at 
Hammersham Bogs; and in Northumberland, at Lears- 
mouth Bogs. In Wales, it is found at Llanberis, in 
Carnarvonshire; at Llwydiard Lake, in Anglesea ; 
and at Cwmbold and Sketty Bogs, in Glamorganshire. 
In Scotland it is rare or absent. In Ireland it is very 
uncommon ; but has been found at Portmore Park, on 
the shore of Lough Neagh, in County Antrim; near 
Lough Carra, in County Mayo; and near Muckross, 
in County Kerry. 
This fern grows freely, provided the soil be suffi- 
ciently peaty, and the supply of moisture abundant; 
if this can be done in no other way it may always be 
accomplished by digging out the ordinary soil and 
making a cemented bottom upon which to spread the 
peat: saturate this thoroughly with water; too much 
cannot be given, as the caudices will thrive equally 
well when constantly submerged. For green-house 
cultivation, use the largest obtainable seed-pan without 
any apertures for the escape of water; sift peat earth 
through a coarse sieve, and mix it with charcoal 
broken small, in the Proportion of seven parts peat 
and one of charcoal: arrange the caudices among 
_ this compost and saturate with water: no protection 
against sun is required.
