"Nay, is it so? St. Senanus be praised!" said Brian, greatly relieved. "Cross to us, maiden; cross to us," he said. "Fear nothing; 't is but Brian, thy foster-brother, returning to his father's home."

The girl swiftly crossed the ford and bowed her golden head in a vassal's welcome to the young lord.

"Welcome home, O brother," she said. "Even now, my lord, thy father awaits the sound of thy horn as he sits in the great seat beneath his kingly shield. And I——"

"And thou, maiden," sad Brian, gayly, "thou must needs lurk behind the haunted rock of Carrick-lee, to freeze the heart of young Brian at his home-coming, with thy banshee song."

Eimer of the golden hair laughed a ringing laugh. "Say'st thou so, brother?" she said. "Does the 'Scourge of the Danes' shrink thus at a maiden's voice?"

"Who calls me the 'Scourge of the Danes'?" asked Brian.

"So across the border do they say that the maidens of King Callaghan's court call the boy Brian, the son of Kennedy," the girl made answer.

"Who faces the Danes, my sister, faces no tender foe," said Brian, "and the court of the King of Cashel is no ladies' hall in these hard-striking times. But wind thy horn, Cogoran, and cross we the ford to greet the king, my father."

Loud and clear the herald's call rose above the rush of the rapids, and as the boy and his followers crossed the ford, the gates of the palace, or dun, of King Kennedy of Thomond were flung open, and the band of welcomers, headed by Mahon, Brian's eldest brother, rode out to greet the lad.

Nine hundred years ago the tribe of Cas was one of the most powerful of the many Irish clans. The whole of Thomond, or North Munster, was under their sway, and from them, say the old records, "it was never lawful to levy rent, or tribute, or pledge, or hostage, or fostership fees," so strong and free were they. When the clans of Munster gathered for battle, it was the right of the Clan of Cas to lead in the attack, and to guard the rear when returning from any invasion. It gave kings to the throne of Munster, and valiant leaders in warfare with the Danes, who, in the tenth century, poured their hosts into Ireland, conquering and destroying. In the year 948, in which our sketch opens, the head of this powerful clan was Cennedigh, or Kennedy, King of Thomond. His son Brian had, in accordance with an old Irish custom, passed his boyhood in "fosterage" at the court of Callaghan, King of Cashel, in East Munster. Brought up amid warlike scenes, where battles with the Danish invaders were of frequent occurrence, young Brian had now, at fifteen, completed the years of his fostership, and was a lad of strong and dauntless courage, cool and clear-headed, and a firm foe of Ireland's scourge—the fierce "Dub-Gaile," or "Black Gentiles," as the Danes were called.
