for a century thereafter Irish expeditions abroad. A
revolution and a restoration followed, in which Moran the
Just Judge played the part of Monk to _his_ Charles II.,
Tuathal surnamed "the Legitimate." It was Tuathal
who imposed the special tax on Leinster, of which, we
shall often hear--under the title of _Borooa_, or Tribute.

Eugenian families of the south, strong in numbers, and
led by a second Owen More, again halved the Island with
the ruling race, the boundary this time being the _esker_,
or ridge of land which can be easily traced from Dublin
west to Galway. Olild, a brave and able Prince, succeeded
in time to the southern half-kingdom, and planted his
own kindred deep and firm in its soil, though the unity
of the monarchy was again restored under Cormac Ulla, or
_Longbeard_. This Cormac, according to the legend, was
in secret a Christian, and was done to death by the
enraged and alarmed Druids, after his abdication and
retirement from the world (A.D. 266). He had reigned full

us, and challenge comparison for truthfulness and foresight
with most uninspired writings.

Cormac's successors during the same century are of little

outposts were renewed with greater energy and on an
increasing scale. Another Crimthan eclipsed the fame of
