THE SNOWDON RANGE OF MOUNTAINS. 213 
Machno, the Lledar, the Llugury, and the Conway, all 
descending from the lofty range which form the west side 
of the valley. 
The Machno has its source to the south-east of Snow- 
don, and, after a run of eight miles, unites its waters with 
the Conway. 
The Lledar takes its rise from some small lakes to the 
south of Dolwyddelan Castle, and, after washing the walls 
of that ancient pile, joins the Llugury above Betteos y 
Coed. 
The Llugury comes from a marshy piece of ground to 
the south of Capel Curig. Near Betteos y Coed, at Rhai- 
dry Wermol, it precipitates itself, in foam and spray, down 
into a chasm 100 feet deep, presenting a grand cascade; 
and at Betteos its waters meet the Conway. 
These three above-described streams take a north-easterly 
direction, and run in narrow rocky channels. 
The Conway, the largest river, and which gives its name 
to this basin, issues from an inconsiderable lake, ten miles 
to the south of Snowdon. Meeting with much obstruction 
from rocks impeding its passage, for a great part of its 
course it is quite a mountain-torrent. When it arrives at 
Betteos, it becomes more tranquil : and at Trefriew, eight 
miles from its mouth, it becomes navigable for vessels of 
light tonnage. 
From this short and hasty description, it is evident that 
the Valley of Conway must afford many interesting scenes 
to the lover of landscape. The mountains rise to a great 
height, with numerous beautiful streams descending from 
their sides, and many lakes enlivening the valleys that are 
formed in their various recesses. From the rivers and 
streams having to form their passage through hard slaty 
rocks, at one time opposing, in the form of immense blocks 
crowding the channel, the farther descent of the water —
