gunnon , within five Miles of it, and was very often there, 
about the Skirts, for many Miles, and in a Boat upon it 
feveral times. I have taken the Survey of a great part 
of the Shore thereof, when I drew the Scheme for ma- 
king the Glan-Bog Navigable, from the Lough thro part 
of the upper Bann to Nervry 3 which was done at fuch a 
time as the Waters were very low, and a large Strand left 
in feveral Places: And many Trees lay in the Verge of 
the Lough, which I believe might fome of them have 
lain there fome hundreds of Years, which had been o- 
vertunM by the Lough's encroaching on the Land, 
where great Woods had grown 3 and many Roots of 
great Trees were ftandingin their proper Places, where 
the Water had prevail'd on th Land, and no Alteration 
in the Wood at all, but it was firm, found Wood, with- 
out any Petrifadbon. 
I have had an occafion, among other Things, to 
talk to Mr. Brorenlow upon this Subjedf, a great part of 
his Efface in Ardmagh , lying contiguous to th o Lough $ 
and he told me, that he did believe that there was not 
any petrifying Quality in the Water 5 for that he had 
made feveral Tryals, and had order’d Holly Stakes to 
be driven into rhe Ground within the Verge of the Lough r 
and that fome of them continued there many Years, but 
that he found no Alteration. 
Yet notwithstanding all this, there has been great 
quantities of fuch fort of Stone, like unto Wood, found 
upon the Strand after great Floods and Storms of Wind, 
which b ve put the Lough into a Ferment •, the Waves 
breaking down the Banks, incroaching on the Land, 
and tumbling over Trees, by which Incroachment this 
fort of Stones are d’fcoverd : And if ever they were 
Wood, they were petrify ’d by the Earth, and no 1 : by 
the Watery of which kind I have feen feveral Pieces big 
and little, fome like Oak, fome Afh, and fome like Holly, 
with Bark, Grain and Knots like Wood 3 fo that any by
