of the calm, but another instant and there is a mighty crash—­a deafening roar; the great wall of water has fallen, and a very sea of churning foam comes leaping, bursting, spouting over rocks and ledges, carrying all before it with a tremendous sweep that seems to be absolutely irresistible until it meets the higher ledges of rock, when it is hurled back, and retires with a watery hiss that suggests the idea of baffled rage.

But it is not conquered.  With the calm majesty of unalterable determination, wave after wave comes on, in slow, regular succession, like the inexhaustible battalions of an unconquerable foe, to meet with a similar repulse again and again.

There is, however, this peculiar difference between the waves on the ordinary seashore and the billows on the Bell Rock, that the latter, unlike the former, are not always defeated.  The spectator on shore plants his foot confidently at the very edge of the mighty sea, knowing that “thus far it may come, but no farther”.  On the Bell Rock the rising tide makes the conflict, for a time, more equal.  Now, the rock stands proudly above the sea:  anon the sea sweeps furiously over the rock with a roar of “Victory!”

Thus the war goes on, and thus the tide of battle daily and nightly ebbs and flows all the year round.

But when the cunning hand of man began to interfere, the aspect of things was changed, the sea was forced to succumb, and the rock, once a dreaded enemy, became a servant of the human race.  True, the former rages in rebellion still, and the latter, although compelled to uphold the light that warns against itself, continues its perpetual warfare with the sea; but both are effectually conquered by means of the wonderful intelligence that God has given to man, and the sea for more than half a century has vainly beat against the massive tower whose foundation is on the Bell Rock.

But all this savours somewhat of anticipation.  Let us return to Ruby Brand, in whose interest we have gone into this long digression; for he it was who gazed intently at the mingled scene of storm and calm which we have attempted to describe, and it was he who thought out most of the ideas which we have endeavoured to convey.

Ruby had lent a hand to work the pump at the foundation-pit that morning.  After a good spell at it he took his turn of rest, and, in order to enjoy it fully, went as far out as he could upon the seaward ledges, and sat down on a piece of rock to watch the waves.

While seated there, Robert Selkirk came and sat down beside him.  Selkirk was the principal builder, and ultimately laid every stone of the lighthouse with his own hand.  He was a sedate, quiet man, but full of energy and perseverance.  When the stones were landed faster than they could be built into their places, he and Bremner, as well as some of the other builders, used to work on until the rising tide reached their waists.

“It’s a grand sight, Ruby,” said Selkirk, as a larger wave than usual fell, and came rushing in torrents of foam up to their feet, sending a little of the spray over their heads.
