It is anchored on the shoalest part of the reef by a rope with a heavy stone made fast to the end of it.

But for the resistance of the turned-up end of the reversed bench, the current would pull the buoy under water.

At night, a paper lantern with a candle in it is fastened on top of the buoy, and this can be seen a mile or more, a little glimmering spark in the waste of blackness.
Nothing delights a cub so much as an opportunity to go out sounding.
There is such an air of adventure about it; often there is danger; it is so gaudy and man-of-war-like to sit up in the stern-sheets and steer a swift yawl; there is something fine about the exultant spring of the boat when an experienced old sailor crew throw their souls into the oars; it is lovely to see the white foam stream away from the bows; there is music in the rush of the water; it is deliciously exhilarating, in summer, to go speeding over the breezy expanses of the river when the world of wavelets is dancing in the sun.

It is such grandeur, too, to the cub, to get a chance to give an order; for often the pilot will simply say, 'Let her go about!' and leave the rest to the cub, who instantly cries, in his sternest tone of command, 'Ease starboard! Strong on the larboard! Starboard give way! With a will, men!' The cub enjoys sounding for the further reason that the eyes of the passengers are watching all the yawl's movements with absorbing interest if the time be daylight; and if it be night he knows that those same wondering eyes are fastened upon the yawl's lantern as it glides out into the gloom and dims away in the remote distance.
One trip a pretty girl of sixteen spent her time in our pilot-house with her uncle and aunt, every day and all day long.

I fell in love with her.
So did Mr.Thornburg's cub, Tom G----.
