related. His story is as follows:--

_The Legend of Llyn y ddau ychain_.

The speckled cow had two calves, which, when they grew up, became strong
oxen. In those days there was a wicked spirit that troubled
Cerrig-y-drudion Church, and the people greatly feared this spirit, and
everybody was afraid, even in the day-time, to pass the church, for
there, day after day, they saw the evil one looking out of the church
windows and grinning at them. They did not know what to do to get rid of
this spirit, but at last they consulted a famous conjuror, who told them
that no one could dislodge their enemy but the _Dau ychain Banawg_. They
knew of the two long-horned cattle which fed on Waen Banawg. There,
therefore, they went, and brought the powerful yoke to the church. After
considerable difficulty they succeeded in dislodging the spirit, and in
securing it to a sledge to which these oxen were yoked, and now
struggling to get free, he was dragged along by the powerful oxen towards
a lake on Hiraethog Mountain, but so ponderous was their load and so
fearful was the spirit's contentions that the sledge ploughed the land
between the church and the lake as they went along, leaving in the course
that they took deep furrows, and when they came to the hill so terrible
were the struggles of the oxen to get along that the marks of their hoofs
were left in the rocks where they may still be seen. When at last they
reached the lake the spirit would not yield, and therefore oxen, sledge,
and spirit were driven into the lake, and thus was the country rid of the
evil one, and hence the name of the lake--the Lake of the Two Oxen--for
the oxen likewise perished in the lake.

The foregoing legend is evidently founded on the older and more obscure
story of Hu Gardarn, or Hu the Mighty, who with his _Dau ychain Banawg_
drew to land the _avanc_ out of _Llyn Llion_, so that the lake burst out
no more to deluge the earth. For, be it known, it was this _avanc_ that
had occasioned the flood. However, there is a rival claimant for the
honour of having destroyed the _avanc_, whatever that might have been,
for, in Hindu Mythology, Vishnu is credited with having slain the monster
that had occasioned the Deluge.

This last bit of Folk-lore about Hu Gadarn, which is found in the
_Triads_, shows how widespread, and how very ancient, Welsh tales are.
Hu Gadarn is by some writers identified with Noah. He was endowed, it
would seem, with all the
