But, in spite of all the efforts of the Jews, the embankment rose steadily, until it almost equaled the height of the wall; and the struggle now went on between the combatants on even terms, they being separated only by the short interval between the wall and bank. Josephus found that in such a conflict the Romans--with their crowd of archers and slingers, and their formidable machines--had all the advantage; and that it was absolutely necessary to raise the walls still higher.

He called together a number of the principal men, and pointed out the necessity for this. They agreed with him, but urged that it was impossible for men to work, exposed to such a storm of missiles. Josephus replied that he had thought of that. A number of strong posts were prepared and, at night, these were fixed securely, standing on the wall. Along the top of these, a strong rope was stretched; and on this were hung, touching each other, the hides of newly-killed oxen. These formed a complete screen, hiding the workers from the sight of those on the embankment.

The hides, when struck with the stones from the ballistae, gave way and deadened the force of the missiles; while the arrows and javelins glanced off from the slippery surface. Behind this shelter, the garrison worked night and day, raising the posts and screens as their work proceeded, until they had heightened the wall no less than thirty-five feet; with a number of towers on its summit, and a strong battlement facing the Romans.

The besiegers were much discouraged at their want of success, and enraged at finding the efforts of so large an army completely baffled by a small town, which they had expected to carry at the first assault; while the Jews proportionately rejoiced. Becoming more and more confident, they continually sallied out in small parties, through the gateway or by ladders from the walls, attacked the Romans upon their embankment, or set fire to it. And it was the desperation with which these men fought, even more than their success in defending the wall, that discouraged the Romans; for the Jews were utterly careless of their lives, and were well content to die, when they saw that they had achieved their object of setting fire to the Roman works.

Vespasian, at length, determined to turn the siege into a blockade; and to starve out the town which he could not capture. He accordingly contented himself by posting a strong force to defend the embankment, and withdrew the main body of the army to their encampment. He had been informed of the shortness of the supply of water; and had anticipated that, in a very short time, thirst would compel the inhabitants to yield.

John had taken his full share in the fighting, and had frequently earned the warm commendation of Josephus. His spirits had risen with the conflict; but he could not shut his eyes to the fact that, sooner or later, the Romans must become masters of the place. One evening, therefore, when he had done his share of duty on the walls, he went up to the house which had been pointed out to him as that in which lived the boy who had descended the face of the rocks, for some distance.

At a short distance from the door, a lad of some fifteen years old, with no covering but a piece of ragged sackcloth round the loins, was crouched up in a corner, seemingly asleep. At the sound of John's footsteps, he opened his eyes in a quick, watchful way, that showed that he had not been really asleep.

"Are you Jonas, the son of James?" John asked.
