There was a sharp yell as Boduoc thrust his spear up through the hole when he saw a pair of eyes, shining in the firelight, appear at the edge. At the same moment there was a sound of scraping and scratching at some of the other holes. The roof was constructed of rough poles laid at short distances apart, and above these were small branches, on which was a sort of thatch of reeds and rushes. Standing close under one of the holes Beric could see nothing, but from the sound of the scratching he could tell from which side the wolf was at work enlarging it. He carefully thrust the point of his spear through the branches and gave a sudden lunge upwards. A fierce yell was heard, followed by the sound of a body rolling down the roof, and then a struggle accompanied by angry snarling and growling outside. "That is one less, Beric," Boduoc said. "I fancy I only scratched mine. Ah!" he exclaimed suddenly, as without the least warning a wolf sprang down through the hole. Before it could gather its legs under it for a fresh spring Beric and the woman both thrust their spears deeply into it, Boduoc keeping his eyes fixed on the hole, and making a lunge as another wolf peered down in readiness to spring after the one that had entered. For hours the fight went on. Gradually the holes, in spite of the efforts of the defenders, were enlarged, and the position became more and more critical. At least twenty of the wolves were slain; but as the attack was kept up as vigorously as at first, it was evident that fresh reinforcements had arrived to the assailants. "We cannot keep them out much longer, Beric," Boduoc said at last. "It seems to me that our only plan is to fire the hut, and then, each taking a child, to make a rush across to the trees and climb them. The sudden burst of fire will drive them back for a little, and we may make good our retreat to the trees." "What time is it, think you, Boduoc?" "It must be two or three hours past midnight, and if Borgon carried out my instructions help ought to be near at hand. I would that we could let them know of our peril." "There is a cow horn," the woman said, pointing to the corner of the hut. "My husband uses it for calling in the cattle." Boduoc seized the horn and blew a deep hollow blast upon it. There was a sudden pattering of feet overhead and then silence. "That has scared them," Beric said. "Blow again, Boduoc; if we can but gain half an hour our friends may be up." Again and again the hoarse roar of the cow horn rose, but the wolves speedily recovered from their scare and crowded on the roof. "We can't hold out much longer," Beric said, as two wolves that leapt down together had just been despatched. "Get a brand from the fire." At this moment there was a sudden scuffle overhead, and the three defenders stood, spear in hand, ready to repel a fresh attack; but all was quiet; then a loud shout rose on the air.
