where a good Footman can fcarce climb op to them* 
That thefe Lakes are yearly fupplied from the Brooks at 
the Bottom of the Mountains I do not at all doubt, efpe- 
cially in Spawning time, when the Trouts endeavour to 
furmount all Difficulties, by palling up the fmall Rivu» 
lets, to depofit their Spawn, for the Prefervation of their 
Species, where it is the raoft fecure from the Violence of 
other Fifties, and there by accident fall into thefe Natural 
Ponds, where they continue all Summer 5 no Perfon 
having yet obferved (that I know of) Trouts to breed 
in Ponds. Not only the Trouts that are taken in thefe 
mountainous Lakes are fmall, but alfo the' Charrs that are 
taken as they afcend the fmall River out of the great 
Lakes nigh Lhan Bery* ,to depofit their Spawn in the Sands 
there. Thefe very rarely exceed a frefti Herring in mag- 
nitude, as I have been allured by the Reverend Mr. 
Evans, Vicar of Lhan Berysy who has been prefent when 
hundreds of them have been caught $ and by*the ac- 
count he gives of them they are in no refpeft diffe- 
rent from thofe taken in JVinandcr-Mear, fave n magni- 
tude, where ’tis no rare thing to meet with them of 
two Pound weight and upwards. This fmallnefs in 
Fifties I have fome time thought to proceed from the 
Coldnefs of the Water, thefe Lakes being fupp'ied with 
Snow Water from the Mountains eight Months in twelve. 
The miner a of Vitriol and AUum, being often met with, 
in the Hills through which fome of the Water mud 
drain, perhaps does not a little contribute to the rough- 
nefs and coldnefs of the Water. The Contrary we find 
in our Waters that run through the Limeftone Reck?, 
where no rough Salts are found $ the Trouts there are 
large and fat. An inftance of this we find in the Trouts 
in Malham Tarr in Craven , nigh Setle, when* they are 
frequently found two Foot long.
