An expression of deep anxiety had begun to supplant the look of hope and confidence they had worn, and some of them were provoked to a doubt whether Frank, in the generosity of his nature, was not intending to let Tony bear off the honors.
"Come, Frank, let her have, now!" said Tim, who could no longer restrain his impatience.
"Silence! Not a word!" said the self-possessed coxswain.
It was in the "order of the day" that no member should speak during the race; and none did, except Tim, and he could easily have been pardoned under the circumstances.
Not yet did Frank quicken the stroke of the Zephyr, though at the end of the next half mile she was only two boats' lengths astern of her competitor, which had lost this distance by the exhaustion of her crew.
They had pulled three miles with the expenditure of all their strength.
They lacked the power of endurance, which could only be obtained by long practice.

"It is the last pound that breaks the camel's back;" and it was so with them.

With a little less exertion they might have preserved some portion of their vigor for the final struggle, which was yet to come.
They had begun upon the last mile.

The crew of the Butterfly were as confident of winning the race as though the laurel of victory had already been awarded to them; and though their backs ached and their arms were nearly numb, a smile of triumph rested on their faces.
"Now for the tug of war," said Frank, in a low, subdued tone, loud enough to be heard by all his crew, but so gentle as not to create any of that dangerous excitement which is sometimes the ruin of the best laid plans.
As he spoke the motions of his body became a little quicker, and gradually increased in rapidity till the stroke was as quick as was consistent with perfect precision.

The result of this greater expenditure of power was instantly observed, and at the end of the next quarter of a mile the boats were side by side again.
"They are beating us!" said Tony, in a whisper.
