the next time, for I shall watch my opportunity when you are
all busy talking, and say, _Attention_, suddenly; then you will
not all stop in an instant, but some will go on just to finish their
sentence, and this will be disobeying the order, and so I shall get
you ashore."

The boys laughed; they thought that it was not very good policy for
Forester to give them this warning of his intention, as it put
them all upon their guard. Presently the word of command came very
suddenly--"_Attention!_" Every voice was hushed in an instant;
the boys assumed immediately an erect position, and looked directly
toward Forester.

"Joseph," said Forester, "when I give order _Toss_, you are
to take up your oar and raise the blade into the air, and hold it
perpendicularly, with the end of the handle resting on the thwart by
your side, on the side of the boat opposite to the one on which you
are going to row,--_Toss!_"

So Joseph raised his oar in the manner directed, the other boys
looking on.

"Let it down again," said Forester. Joseph obeyed.

"_Crew at ease_," said Forester.

Forester acted very wisely in not keeping the attention of the crew
very long at a time. By relieving them very frequently, he made the
distinction between being under orders and at ease a very marked
and striking one, so that the boys easily kept it in mind. In a few
moments he commanded attention again, with the same success as before.
He then ordered another boy to toss his oar, then another, and so on,
until he had taught the movement to each one separately. He gave to
each one such explanations as he needed, and when necessary he made
them perform the evolution twice, so as to be sure that each one
understood exactly what was to be done. Then Forester gave the command
for them all to toss together, and they did so quite successfully. The
oars rose and stood perpendicularly like so many masts; while Forester
paddled the boat slowly through the water. Then he directed the boys
to let the oars down again, gently, to their places along the thwarts,
and put the crew at ease.

The boys perceived now that they were making progress. They were
gaining slowly, it is true, but surely, and Marco saw where the cause
of his failure was. He had not realized how entirely ignorant all
these boys were of the whole mystery of managing an oar and of acting
in concert; and besides, he had not had experience enough as a
teacher, to know how short the steps must be made
