"You're up in all that kind of wigwag signal work, and perhaps now you could tell what it means." "I lost some of it, I'm sorry to say, fellows," observed Hugh, gravely; "but all the same I caught enough to tell me that waving of a light was meant as a signal message, though who sent it, and to whom, is all a mystery." "But could you make out enough of the message, Hugh, to give you any idea what it stood for ?" persisted Thad.
"Yes, I believe I did," the other admitted, solemnly, so that each of his chums bent closer to catch the next words that fell from his lips.

"I'm certain it spelled out the word 'help,' for one; and I thought another was 'quick'!" "Oh! what do you think of that ?" gasped Horatio.
"The mystery deepens," added Owen, dramatically, just as he had probably been accustomed to reading in some story of excitement.
"Of course," continued Hugh, immediately, "we've got to take a look around that same old quarry, and see what's going on.

Somebody's holding the fort there, even if it is said to be deserted.

Who and what he can be, of course, remains to be seen; but I'm not taking a bit of stock in those old wives' yarns about a ghost, remember, Horatio." "Then we'll have to leave the car on the road, won't we, Hugh, when we tackle this big job ?" questioned Owen.
"Of course; and since I marked the best spot where anyone could make their way along to the face of the quarry, we must start up again, and keep moving till we strike that place." "But, Hugh, do you think the--er--party making those signals with a light could have noticed our illumination, and that message was meant for us ?" Horatio went on to ask, solicitously.
"I'm not prepared to say," he was told, "though I don't see how anybody with eyes could miss discovering us coming along.

And, besides, the old car makes plenty of noise in the bargain, to attract attention.
