Then Fergus was in sore perplexity; and pondering a little he said:—"I will not forsake the sons of Usna: for I will send with them to Emain Macha my two sons, Illan the Fair and Buinni the Red, who will be their pledge instead of me."

But Naisi said: "We need not thy sons for guard or pledge: we have ever been accustomed to defend ourselves!" And he moved from the place in great wrath: and his two brothers, and Deirdre, and the two sons of Fergus followed him, with the rest of the clan; while Fergus remained behind silent and gloomy: for his heart misgave him that mischief was brewing for the sons of Usna.

Then Deirdre tried to persuade the sons of Usna to go to Rathlin, between Erin and Alban, and tarry there till Barach's feast was ended: but they did not consent to do so, for they deemed it would be a mark of cowardice: and they sped on by the shortest ways towards Emain Macha.

When now they had come to Fincarn of the Watch-tower on Slieve Fuad, Deirdre and her attendants stayed behind the others a little: and she fell asleep. And when Naisi missed her, he turned back and found her just awakening; and he said to her:—"Why didst thou tarry, my princess?"

And she answered:—"I fell asleep and had a dream. And this is what I saw in my dream:—Illan the Fair took your part: Buinni the Red did not: and I saw Illan without his head: but Buinni had neither wound nor hurt."

"Alas, O beauteous princess," said Naisi, "thou utterest nought but evil forebodings: but the king is true and will not break his plighted word."

So they fared on till they had come to the Ridge of the Willows,[CLXXVI.] an hour's journey from the palace: and Deirdre, looking upwards in great fear, said to Naisi:—"O Naisi, see yonder cloud in the sky over Emain, a fearful chilling cloud of a blood-red tinge: a baleful red cloud that bodes disaster! Come ye now to Dundalgan and abide there with the mighty hero Cuculainn till Fergus returns from Barach's feast; for I fear Concobar's treachery."

But Naisi answered:—"We cannot follow thy advice, beloved Deirdre, for it would be a mark of fear: and we have no fear."

And as they came nigh the palace Deirdre said to them:—"I will now give you a sign if Concobar meditates good or evil. If you are brought into his own mansion where he sits surrounded by his nobles, to eat and drink with him, this is a token that he means no ill; for no man will injure a guest that has partaken of food at his table: but if you are sent to the house of the Red Branch, be sure he is bent on treachery."
