e distance than very close at hand. The
whistle signals are seldom necessary, however; never, perhaps, except
when the wind confuses the significant ripples upon the water's surface.
When the yawl has reached the shoal place, the speed is slackened, the
pilot begins to sound the depth with a pole ten or twelve feet long,
and the steersman at the tiller obeys the order to 'hold her up to
starboard;' or, 'let her fall off to larboard;'{footnote [The term
'larboard' is never used at sea now, to signify the left hand; but was
always used on the river in my time]} or 'steady--steady as you go.'

When the measurements indicate that the yawl is approaching the shoalest
part of the reef, the command is given to 'ease all!' Then the men stop
rowing and the yawl drifts with the current. The next order is, 'Stand
by with the buoy!' The moment the shallowest point is reached, the pilot
delivers the order, 'Let go the buoy!' and over she goes. If the pilot
is not satisfied, he sounds the place again; if he finds better water
higher up or lower down, he removes the buoy to that place. Being
finally satisfied, he gives the order, and all the men stand their
oars straight up in the air, in line; a blast from the boat's whistle
indicates that the signal has been seen; then the men 'give way' on
their oars and lay the yawl alongside the buoy; the steamer comes
creeping carefully down, is pointed straight at the buoy, husbands her
power for the coming struggle, and presently, at the critical moment,
turns on all her steam and goes grinding and wallowing over the buoy and
the sand, and gains the deep water beyond. Or maybe she doesn't; maybe
she 'strikes and swings.' Then she has to while away several hours (or
days) sparring herself off.

Sometimes a buoy is not laid at all, but the yawl goes ahead, hunting
the best water, and the steamer follows along in its wake. Often there
is a deal of fun and excitement about sounding, especially if it is a
glorious summer day, or a blustering night. But in winter the cold and
the peril take most of the fun out of it.

A buoy is nothing but a board four or five feet long, with one end
turned up; it is a reversed school-house bench, with one of the supports
left and the other removed. 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. A
