As Dick turned out the lamp the flickering lightning played through the window, showing Wyatt crossing to his chamber door, which he opened, turned, said “Good-night, old man,” and closed after him.

Dick yawned heavily and went to the sitting-room door, which he threw open, disturbing his man, who, in company with Wyatt’s servant, was asleep on the mat; and then, satisfied that the men were there, he closed the door again, went to that of his own room, and passed through, leaving the door of communication open.

There was no light in the slightly-furnished bedchamber, and he felt that he did not need one, for it would only add to the heat of the place; so he partially undressed before going to the open window. This looked out on the shaded terrace, and he stood there gazing out at the darkness, which was cut every now and then by the flickering lightning, the latter being followed at intervals of several seconds by the muttering of the thunder far away in the mountains to the north.

“Phew! how hot it is!” muttered Dick. “Wish I was a fish.”

All was wonderfully still in the courtyard below, and the darkness seemed mysterious and strange, till there was an impatient stamp from a horse’s hoof, which sounded echoing and loud. Then the stillness and darkness grew oppressive as the heat, and a peculiar nervous sensation came over the lad as he thought of their loneliness away there among strangers, and what the consequences would be if the people rose against them at a time like that. How helpless they would be against the lithe, knife-armed enemy if they surprised them in such a darkness as seemed to fill the courtyard!

As he looked down, his imagination peopled the place with fierce-eyed enemies, each armed with a keen knife, and the perspiration gathered upon his face till the drops ran together and began to run down by the sides of his nose with a troublesome, tickling sensation.

It was horrible! A night like this would be just such a one as the enemy might choose for an attack, and, with the nervous excitement increasing, the lad leaned out as far as he could, wondering why he could not hear something of the sentries.

Then the whole of the northern sky was lit up by a pale, lambent sheet of lightning, and there beneath him was the courtyard, clearly seen, with the guns, limbers, and wagons; while, before the distant muttering of the thunder could reach his ears, the regular tramp of the sentry by the gate rose to where he stood.

“I don’t wonder at little children being afraid to be in the dark,” mused Dick. “How cowardly it does make one seem! It must be the peculiar feeling brought on by the coming storm. Ugh! if a flash were to strike our magazine!”

Dick left the window open and finished undressing. Then, throwing himself upon the light charpoy, which felt like everything else, hot, he closed his eyes so as to have a good sleep; and, as a matter of course, although he could hardly keep his eyes open when in the next room with his brother-officer, he felt now thoroughly wide-awake and as if sleep was the last thing possible.
