And in this wor k the chief part was taken by Manw ?and Aul?andthe Valar fortified their dwelling, and upon the shores of the sea they raised the Pel 髍 i, the Mountains of Aman, highest upon Earth. A nd above all the mountains of the Pel 髍 i was that height upon whose summit Manw ?set his throne. Taniquetil the E lves name that holy mountain, and O ioloss?Everlasting Whiteness, and Elerr 韓 a Crowned with Stars, and many names beside。 but the Sindar spoke of it in their later tongue as Amon Uilos. From their halls upon Taniquetil Manw?and Varda could look out a cross the Earth even into the furthest East. Behind the walls of the Pel 髍 i the Valar established their domain in that region which is called Valinor, and there were their houses, their gardens, and their towers. In that guarded land the Valar gathered great store of light and an the fairest things that were saved from the ruin。 and many others yet fairer they made anew, and Valinor became more beautiful even than Middle earth in the Spring of Arda。 and it was blessed, for the Deathless dwe lt there, and there naught faded nor withered, neither was there any stain upon flower or leaf in that land, nor any corruption or sic kness in anything that lived。 for the very stones and waters were when Valinor was fullwrought and the mansions of the Valar were established, in the midst of the plain beyond the mountains they built their city, Valmar of many bells. Before its western gate there was a green mound, Ezellohar, that is named also Corollair ? and Yavanna hallowed it, and she sa t there long upon the green grass and sang a song of power, in which was set all her thought of things that grow in the earth. But Nienna thought in silence, and watered the mould witho that the first designs of the Valar were never after restored. In the confusion and the darkness Melkor escaped, though fear fell upon him。 for above the roaring of the seas he heard the voice of Manw ?as a mighty wind,unfolding of the things that they had devisedd into a long tunnel of misery, with hope growing ever fainter behind. They ran, and they ran, striving to keep up the pace set by the Orcs, lic ked every now and again with a cruel thong cunningly handled. If they halted or stumbled, they were seized and dragged for some distance. The warmth of the orcdraught had gone. Pippin felt cold and sic k again. Suddenly he fell face downward on the turf. Hard hands with rending nails gripped and lifted him. He was c arried like a sac k once more, and darkness grew about him: whether the darkness of another night, or a blindness of his eyes, he could not tell. Dimly he became aware of voices clamouring: it seemed that many of the Orcs were demanding a halt. Ugl 鷎 was shouting. He felt himself flung to the ground, and he lay as he fell, till blac k dreams took him. But he did not long escape from pain。 soon the iron grip of merciless hands was on him again. For a long time he was tossed and sha ken, and then slowly the dar kness gave way, and he came back to the waking world and found that it was morning. Orders were shouted and he was thrown roughly on the grass. 第 23 頁 共 22 頁 There he lay for a while, fighting with despair. His head swam, but from the heat in his body he guessed that he had been given another draught. An Orc stooped over him, and flung him some bread and a strip of raw dried flesh. He ate the stale grey bread hungrily, but not the meat. He was famished but not yet so famished as to eat flesh flung to him by an Or c, the flesh of he dared not guess what creature. He sat up and looked about. Merry was not far away. They were by the banks of a swift narrow river. Ahead mountains loomed: a tall pea k was catching the first rays of the sun. A dark smudge of forest lay on the lower slopes before them. There was much shouting and debating among the Orcs。 a quarrel seemed on the point of brea king out again between the Northerners and the Isengarders. Some were pointing bac k away south, and some were pointing eastward. 39。Very well,39。 said Ugl 鷎 . 39。Leave them to me then! No killing, as I39。ve told you before。 but if you want to throw away what we39。ve e all the way to get, throw it away! I39。ll look after it. Let the fighting Urukhai do the wor k, as usual. If you39。re afraid of the Whiteskins, run! Run! There39。s the forest,39。 he shouted, pointing ahead. 39。Get to it! It39。s your best hope. Off you go! And quic k, before I knock a few more heads off, to put some sense into the others.39。 There was some cursing and scuffling, and then most of the Northerners broke away and dashed off, over a hundred of them, running wildly along the river towards the mountains. The hobbits were left with the Isengarders: a grim dark band, four score at least of large, swart, slanteyed Orcs with great bows and short broadbladed swords. A few of the larger and bolder Northerners remained with them. 39。Now we39。ll deal with Grishn 醟 h,39。 said Ugl 鷎 。 but s
