This was dreadful talk to listen to, not only because of the brave woodmen and their wives and children, but also because of the danger which now threatened Gandalf and his friends. The Wargs were angry and puzzled at finding them here in their very meeting-place. They thought they were friends of the woodmen, and were come to spy on them, and would take news of their plans down into the valleys, and then the goblins and the wolves would have to fight a terrible battle instead of capturing prisoners and devouring people waked suddenly from their sleep. So the Wargs had no intention of going away and letting the people up the trees escape, at any rate not until morning. And long before that, they said, goblin soldiers would be coming down from the mountains; and goblins can climb trees, or cut them down.
Now you can understand why Gandalf, listening to their growling and yelping, began to be dreadfully afraid, wizard though he was, and to feel that they were in a very bad place, and had not yet escaped at all. All the same he was not going to let them have it all their own way, though he could not do very much stuck up in a tall tree with wolves all round on the ground below. He gathered the huge pine-cones from the branches of the tree. Then he set one alight with bright blue fire, and threw it whizzing down among the circle of the wolves. It struck one on the back, and immediately his shaggy coat caught fire, and he was leaping to and fro yelping horribly. Then another came and another, one in blue flames, one in red, another in green. They burst on the ground in the middle of the circle and went off in coloured sparks and smoke. A specially large one hit the chief wolf on the nose, and he leaped in the air ten feet, and then rushed round and round the circle biting and snapping even at the other wolves in his anger and fright.
The dwarves and Bilbo shouted and cheered. The rage of the wolves was terrible to see, and the commotion they made filled all the forest. Wolves are afraid of fire at all times, but this was a most horrible and uncanny fire. If a spark got in their coats it stuck and burned into them, and unless they rolled over quick they were soon all in flames. Very soon all about the glade wolves were rolling over and over to put out the sparks on their backs, while those that were burning were running about howling and setting others alight, till their own friends chased them away and they fled off down the slopes crying and yammering and looking for water.
“What is all this uproar in the forest tonight?” said the Lord of the Eagles. He was sitting, black in the moonlight, on the top of a lonely pinnacle of rock at the eastern edge of the mountains. “I hear wolves’ voices! Are the goblins at mischief in the woods?”
He swept up into the air, and immediately two of his guards from the rocks at either hand leaped up to follow him. They circled up in the sky and looked down upon the ring of the Wargs, a tiny spot far far below. But eagles have keen eyes and can see small things at a great distance. The Lord of the Eagles of the Misty Mountains had eyes that could look at the sun unblinking, and could see a rabbit moving on the ground a mile below even in the moonlight. So though he could not see the people in the trees, he could make out the commotion among the wolves and see the tiny flashes of fire, and hear the howling and yelping come up faint from far beneath him. Also he could see the glint of the moon on goblin spears and helmets, as long lines of the wicked folk crept down the hillsides from their gate and wound into the wood.
Eagles are not kindly birds. Some are cowardly and cruel. But the ancient race of the northern mountains were the greatest of all birds; they were proud and strong and noble-hearted. They did not love goblins, or fear them. When they took any notice of them at all (which was seldom, for they did not eat such creatures), they swooped on them and drove them shrieking back to their caves, and stopped whatever wickedness they were doing. The goblins hated the eagles and feared them, but could not reach their lofty seats, or drive them from the mountains.
Tonight the Lord of the Eagles was filled with curiosity to know what was afoot; so he summoned many other eagles to him, and they flew away from the mountains, and slowly circling ever round and round they came down, down, down towards the ring of the wolves and the meeting-place of the goblins.
A very good thing too! Dreadful things had been going on down there. The wolves that had caught fire and fled into the forest had set it alight in several places. It was high summer, and on this eastern side of the mountains there had been little rain for some time. Yellowing bracken, fallen branches, deep-piled pine-needles, and here and there dead trees, were soon in flames. All round the clearing of the Wargs fire was leaping. But the wolf-guards did not leave the trees. Maddened and angry they were leaping and howling round the trunks, and cursing the dwarves in their horrible language, with their tongues hanging out, and their eyes shining as red and fierce as the flames.
Then suddenly goblins came running up yelling. They thought a battle with the woodmen was going on; but they soon learned what had really happened. Some of them actually sat down and laughed. Others waved their spears and clashed the shafts against their shields. Goblins are not afraid of fire, and they soon had a plan which seemed to them most amusing.
Some got all the wolves together in a pack. Some stacked fern and brushwood round the tree-trunks. Others rushed round and stamped and beat, and beat and stamped, until nearly all the flames were put out—but they did not put out the fire nearest to the trees where the dwarves were. That fire they fed with leaves and dead branches and bracken. Soon they had a ring of smoke and flame all round the dwarves, a ring which they kept from spreading outwards; but it closed slowly in, till the running fire was licking the fuel piled under the trees. Smoke was in Bilbo’s eyes, he could feel the heat of the flames; and through the reek he could see the goblins dancing round and round in a circle like people round a midsummer bonfire. Outside the ring of dancing warriors with spears and axes stood the wolves at a respectful distance, watching and waiting.
He could hear the goblins beginning a horrible song:
Fifteen birds in five fir-trees,
their feathers were fanned in a fiery breeze!
But, funny little birds, they had no wings!
O what shall we do with the funny little things? Roast ’em alive, or stew them in a pot;
fry them, boil them and eat them hot?
Then they stopped and shouted out: “Fly away little birds! Fly away if you can! Come down little birds, or you will get roasted in your nests! Sing, sing little birds! Why don’t you sing?”
“Go away! little boys!” shouted Gandalf in answer. “It isn’t bird-nesting time. Also naughty little boys that play with fire get punished.” He said it to make them angry, and to show them he was not frightened of them—though of course he was, wizard though he was. But they took no notice, and they went on singing.
