"Assuredly!" said the other; "but I will add a remedy, which will greatly aid his cure. It is a secret however, which no one must hear. If you two gentlemen will retire for a moment, I will join you at the door immediately."

Oberntraut instantly withdrew, without reply; and Dr. Alting followed more slowly. But as soon as they were in the corridor, and the door closed, Oberntraut grasped the old man's arm, saying, in a low tone, and with an agitated look, "This is a terrible risk!--we have no force to defend the town, in case of sudden attack. 'Twere better to send off for Vere and his men directly, and leave Mannheim to its fate, rather than suffer the King's person to be so risked;" and he took a step towards the head of the stairs.

"Stay, stay!" cried Dr. Alting, catching him by the sleeve; "let us hear farther, ere you act."

CHAPTER VIII.

The sun had set; the young moon had risen; and the sky of the early spring-time was full of stars. A great deal of bustle had been observed in the castle, though it was now no longer tenanted by a host of servants, and the gay scene of courtly splendour which it had formerly displayed--the hurrying multitudes, the splendid dresses, the clanging trumpets, and the beating drums, had subsided into dulness, silence, and almost solitude. The ruined fortunes of the Palatinate house were shadowed forth in the desolate change which had come over their dwelling-place.

Yet, as I have said, an unusual degree of activity had appeared in the castle during the last two hours before sunset. Some seven or eight mounted men had gone forth in different directions, none of the ordinary inhabitants of the place knowing what was their errand. The young Baron of Oberntraut himself rode out, followed by a single trooper; but, instead of going down into the plain, which was the direction he usually took, and where his men were quartered, he rode up by steep and precipitous paths--where, perhaps, a horse's hoof had never trod the ground before--round the hills looking upon the Rhine, and going from height to height, often paused to gaze, shading his eyes with his hand, and seeming to scrutinize every path and road in the wide extent of country below him.

At length, just at sunset, he had returned to the castle, and inquired if any of the messengers had come back. Three had already arrived; and he examined them strictly as to what discoveries they had made in regard to the movements of the enemy's troops. They all agreed that Tilly and his forces had passed over the bridge which he had thrown across the Neckar, had then directed his course towards the Rhine, and had crossed that river near Oppenheim.

This news seemed to give the young officer great satisfaction; and he proceeded from the court to the lodging of Colonel Herbert, where the door was carefully closed after his entrance. About an hour subsequently, as good a meal as could be prepared in the castle was carried up to the rooms of the English officer; but his own servant and Agnes Herbert received the dishes at the door, and the ordinary attendants were not suffered to enter. Another hour elapsed, and then Herbert and Dr. Alting came down the stairs together, looked everywhere round when they reached the door of the tower, and then walked slowly on, taking their way along the inner rampart towards the library-tower, and thence, by the small doors and steps, into the garden. There they turned towards the grating of the arch by which Dr. Alting had been brought that morning to the castle; and Herbert, opening the gate, paused beside it conversing with his old friend.

They had been followed, however, for some way by another party; for, while they were walking along the rampart, Agnes had descended the stairs with the gentleman who had accompanied the old professor in the morning; and they, too, took their way to the gardens. The young Baron of Oberntraut, and Colonel Herbert's servant armed with a stout tuck, followed at a distance of about fifty yards, and, in whichever way Agnes and her companion turned their steps, kept them still in sight.

The fair lady's path seemed somewhat devious: now it was directed towards the lower garden; then, at a word from the gentleman by her side, she mounted the steps, and wound round amongst the trees above, towards the great terrace; then down to the parterres with their curious arabesques; then up again by another flight of steps to the terrace once more; the moon shining bright upon their path the whole way.
