Paul's adventure in the old house somehow seemed to give importance to his opinions on all matters pertaining to that subject. So when he suggested that the act of throwing something into the water by the tenant of the abandoned building was for the purpose of destroying evidence, all the boys agreed that quite likely such was the truth.

What evidence this person, be he Grandall or not, wished to destroy and why, was the subject of vast discussion. Since the coming of Slider among them, particularly, the Auto Boys found the mystery of the stolen twenty thousand dollars to possess for them a strong personal interest. They talked over and over again, and with the greatest relish, everything that had come within their notice in and around the bleak old structure down there on the Point.

Finally–it was during the Sunday evening supper of cold hard-boiled eggs, bread and butter, bananas, graham crackers and coffee–that finally, and at last, Phil Way proposed that a really serious visit be made to the clubhouse the following morning. Of any person encountered–Mr. Murky excepted, of course–permission to use the vise and other equipment in the automobile shed would be asked. This would be a reasonable pretext for going to the clubhouse grounds. And being on those premises, everyone should look carefully about for some clue to the stolen money's hiding place.

It was not easy for Captain Phil to suggest this plan. He was not sure it was quite square and honorable–"on the level"–as some would say,–but he called it a stratagem in a worthy cause and so felt better over it. But really, since the cause was that of helping Chip Slider, as against such villains as Murky and Grandall, no one could blame Phil, or blame any of the lads that they welcomed his proposal heartily.

The day had been hot and close. Contrary to the usual condition, also, the air grew little if any cooler as night came on. A dive from the projecting log into the lake to cool off was in order then, as the boys prepared for bed.

"Just goes to show what a nuisance clothes are, anyway," observed Paul Jones, as he dried himself. He was rejoicing exceedingly that he had only to jump into his nightshirt to be clothed to all necessary extent, following his swim. "Heap fine idea if we had clothes for day time as simple as for night time!" he added.

"Yes sir, it's just such fellows as you, Jones, that would sooner or later drift right back to the stone age if there weren't more energetic ones to drag you along forward, making you wear clothes and things–keeping you civilized," was MacLester's answer. A good-natured grin accompanied his remarks.

"Well, I s'pose it takes clothes to give some folks an appearance of being civilized," was Paul's warm rejoinder, yet with utmost good-nature. "But for my part–well, I'll go on wearing 'em, David, for your sake."

"And it would make your appearance more civilized still if you made more civil use of your tongue," MacLester retorted.

Then Jones had recourse to his usual, "Tush, tush, Davy! You've tired yourself all out. You'll feel better tomorrow."
