"We mustn't sit here crowin' like idiots!" he cried sharply as he began to gather up the gold-pieces which had fallen on the ground. "There's no tellin' how soon somebody may come, an' if we want to hold what we've got it's time things around here were put into shape. These bags must be carried on board the Sea Bird, an' the hole filled in ag'in, so's no one will know we've been diggin'!"

This suggestion started the remainder of the party into activity, and on the instant all were ready to set about the necessary work.

It was now high noon. The rays of the sun beat down upon the sand with a heat that under any other circumstances would have seemed overpowering; but the treasure-finders heeded it not. The foliage shut out every breath of air, and the shadows cast by the trees were but so many stifling spots free only from the glare of the sand; yet no one hesitated to begin the laborious task, because the burdens were golden. Over all had come the fear that this new-found treasure might be wrested from them, and hunger or thirst, fatigue or exhaustion were alike forgotten.

"A couple of bags are as much as Joe an' me can carry, while one will be a load for you boys; but in three turns we'll have them all at the boat; so let's get under way at once," Bob said as he set the example, while the others obeyed silently.

No one speculated as to why so much gold had been buried in that particular spot, or how it happened that those who concealed the treasure had abandoned the rich hoard. The wonderful fact of its having come into their possession was the only thought which could be entertained.

The burdens, as allotted by Bob, were reasonably heavy, and despite the excitement which lent fictitious strength, the journey to the boat occupied considerably more than half an hour.

Joe and Bob scanned the horizon in every direction before depositing the first load of treasure to return for the second, but as no sail was in sight on the dazzling blue waters it was believed safe to leave the precious bags on the beach during the hour they would necessarily be absent.

On the third trip neither Harry nor Walter carried a load. There were originally but nineteen packages in the excavation, as was shown by careful count, and since the two boys showed more signs of weariness than the others, Bob insisted that both travel empty-handed.

When the tired party arrived at the beach with the last of the gold the boat was launched, the bags distributed evenly fore and aft, and with Joe and Bob rowing, the return to the steamer was begun.

The movement of the yawl caused a light breeze which greatly refreshed the heated treasure-seekers, and with the relief thus afforded came speculation as to why so much wealth had been concealed on the key.
