He had hardly said the words when a thick fog wrapped itself around him , and so thick was it that he could not see his own hand , or hear the sound of his voice . For a day and a night he fought with his sword , without ever once seeing his enemy , then suddenly the fog began to lighten . By dawn of the second day it had vanished altogether , and the sun shone brightly in the heavens . It seemed to Petru that he had been born again . And the Welwa ? She had vanished . ` You had better take breath now you can , for the fight will have to begin all over again , ' said the horse . ` What was it ? ' asked Petru . ` It was the Welwa , ' replied the horse , ` changed into a fog ` Listen ! She is coming ! ' And Petru had hardly drawn a long breath when he felt something approaching from the side , though what he could not tell . A river , yet not a river , for it seemed not to flow over the earth , but to go where it liked , and to leave no trace of its passage . ` Woe be to me ! ' cried Petru , frightened at last . ` Beware , and never stand still , ' called the brown horse , and more he could not say , for the water was choking him . The battle began anew . For a day and a night Petru fought on , without knowing at whom or what he struck . At dawn on the second , he felt that both his feet were lame . ` Now I am done for , ' thought he , and his blows fell thicker and harder in his desperation .
And the sun came out and the water disappeared , XXXXX his knowing how or when .
