“Can’t tell, I’m sure,” said I, looking across the river towards the spot where the other tower showed itself above the trees. “I fail to see signs of anything distressful. Time was when I knew what ailed the boys in Cambridge—but that time’s long gone by! What seems to be the excitement at the present moment?”

“That’s what I want to know,” said Kenryck, as the young fellow upon the turret began to call off the signals from the second station. “They’ve just sent this message—it’s being flagged over from the hill now—‘Big trouble here! Want advice. Shall we explain?’ Now what does that mean?”

“Ask ’em,” said I promptly. “Wig-wag the information that I’m here—ready to furnish advice in car-load lots as soon as they’ve sent on their explanation.”

“Thanks!” said my friend, with dry politeness. “I’m more than fortunate in having you with me.” Then, to the man with the flag, “O.K. that last message, Millar, and add, ‘Explain.’”

Up and down, sidewise and to the front, went the flapping square of red bunting with its core of snowy white; while Kenryck, in readiness to catch the first responsive signal, trained his glasses upon the ‘cross-river station.

“Here it comes,” he said, as the distant speck of color awoke to spasmodic and rapid motion. “Now we shall be given understanding. Hello! the sergeant must be doing the flagging: Orcutt couldn’t send the words along at that rate of speed.”

“Translate for my benefit, Ken., will you?” said I, coming over to his side. “I’m consumed by curiosity. I’ll swear solemnly not to let any information fall into the hands of the enemy.”

“Pick up my note-book,” he answered hurriedly, without changing his position or allowing his eyes to wander for an instant from the opposite tower, “and scratch down what I give you. Ready? Well, then, start off with this: ‘Man—making—fuss—at—base—of—tower.’ Got that? ‘Says—Orcutt—owes—him—big—money.’”

“Yes I’ve got it: all of it,” said I, snapping a rubber band across the page as a check upon its tendency to get away from me in the fresh breeze. “Very interesting, so far. Go on, old man: give us another chapter of it. I’m waiting.”

“Ease away on your chatter, can’t you?” said Kenryck, a trifle earnestly. “You’ll get me all balled-up in my receiving. Here, take this: ‘Man’s—confounded—insolent: standing—in—street: shouting—all—sorts—of—abuse—up—at—Orcutt.’ There, the sergeant’s stopped sending, to give us a chance to digest what we already have.”
