At last he became somewhat accustomed to the rush of waters and the tremulous motion of the beacon.  His frame, too, exhausted by a day of hard toil, refused to support itself, and he sank into slumber.  But it was not unbroken.  A falling cinder from the sinking fire would awaken him with a start; a larger wave than usual would cause him to spring up and look round in alarm; or a shrieking sea-bird, as it swooped past, would induce a dream, in which the cries of drowning men arose, causing him to awake with a cry that set Pup barking furiously.

Frequently during that night, after some such dream, Bremner would get up and descend to the mortar-gallery to see that all was right there.  He found the waves always hissing below, but the starry sky was calm and peaceful above, so he returned to his couch comforted a little, and fell again into a troubled sleep, to be again awakened by frightful dreams of dreadful sights, and scenes of death and danger on the sea.

Thus the hours wore slowly away.  As the tide fell the noise of waves retired a little from the beacon, and the wearied man and dog sank gradually at last into deep, untroubled slumber.

So deep was it, that they did not hear the increasing noise of the gulls as they wheeled round the beacon after having breakfasted near it; so deep, that they did not feel the sun as it streamed through an opening in the woodwork and glared on their respective faces; so deep, that they were ignorant of the arrival of the boats with the workmen, and were dead to the shouts of their companions, until one of them, Jamie Dove, put his head up the hatchway and uttered one of his loudest roars, close to their ears.

Then indeed Bremner rose up and looked bewildered, and Pup, starting up, barked as furiously as if its own little black body had miraculously become the concentrated essence of all the other noisy dogs in the wide world rolled into one!

CHAPTER XXII

LIFE IN THE BEACON—­STORY OF THE EDDYSTONE LIGHTHOUSE

Some time after this a number of the men took up their permanent abode in the beacon house, and the work was carried on by night as well as by day, when the state of the tide and the weather permitted.

Immense numbers of fish called poddlies were discovered to be swimming about at high water.  So numerous were they, that the rock was sometimes hidden by the shoals of them.  Fishing for these thenceforth became a pastime among the men, who not only supplied their own table with fresh fish, but at times sent presents of them to their friends in the vessels.

All the men who dwelt on the beacon were volunteers, for Mr. Stevenson felt that it would be cruel to compel men to live at such a post of danger.  Those who chose, therefore, remained in the lightship or the tender, and those who preferred it went to the beacon.  It is scarcely necessary to add, that among the latter were found all the “sea-sick men!”
