That day the cows wandered father than ever they had done before, and never stopped till they had reached a moor where the heather was burning. The fire was fierce, but the cows took no heed, and walked steadily through it, Covan the Brown-haired following them. Next they plunged into a foaming river, and Covan plunged in after them, though the water came high above his waist. On the other side of the river lay a wide plain, and here the cows lay down, while Covan looked about him. Near him was a house built of yellow stone, and from it came sweet songs, and Covan listened, and his heart grew light within him. While he was thus waiting there ran up to him a youth, scarcely able to speak so swiftly had he sped; and he cried aloud: ‘Hasten, hasten, Covan the Brown-haired, for your cows are in the corn, and you must drive them out!’ ‘Nay,’ said Covan smiling, ‘it had been easier for you to have driven them out than to come here to tell me.’ And he went on listening to the music. Very soon the same youth returned and cried with panting breath: ‘Out upon you, Covan son of Gorla, that you stand there agape. For our dogs are chasing your cows, and you must drive them off!’ ‘Nay, then,’ answered Covan as before, ‘it had been easier for you to call off your dogs than to come here to tell me.’ And he stayed where he was till the music ceased. Then he turned to look for the cows, and found them all lying in the place where he had left them; but when they saw Covan they rose up and walked homewards, taking a different path to that they had trod in the morning. This time they passed over a plain so bare that a pin could not have lain there unnoticed, yet Covan beheld with surprise a foal and its mother feeding there, both as fat as if they had pastured on the richest grass. Further on they crossed another plain, where the grass was thick and green, but on it were feeding a foal and its mother, so lean that you could have counted their ribs. And further again the path led them by the shores of a lake whereon were floating two boats; one full of gay and happy youths, journeying to the land of the Sun, and another with grim shapes clothed in black, travelling to the land of Night. ‘What can these things mean?’ said Covan to himself, as he followed his cows. Darkness now fell, the wind howled, and torrents of rain poured upon them. Covan knew not how far they might yet have to go, or indeed if they were on the right road. He could not even see his cows, and his heart sank lest, after all, he should have failed to bring them safely back. What was he to do? He waited thus, for he could go neither forwards nor backwards, till he felt a great friendly paw laid on his shoulder. ‘My cave is just here,’ said the Dog of Maol- mor, of whom Covan son of Gorla had heard much. ‘Spend the night here, and you shall be fed on the flesh of lamb, and shall lay aside three-thirds of thy weariness.’
