The Radio Boys on Secret Service Duty

Jack waked early the next morning and lay in his berth wondering drowsily for several moments as to what caused his feeling that there was something unusual in the situation. Th...

"Excuse me for butting in, stranger," said a pleasant voice at the door of the Pullman stateroom, "but I heard you talkin' to these boys about the old mining camps in these Cali...

It was early twilight when a taxicab deposited Mr. Temple and the chums at the entrance to the pier. At the suggestion of Inspector Burton, the boys had purchased and donned cor...

While Jack continued working at the radio, Bob and Frank listened intently. Jack began speaking into the transmitter, indicating he had opened communication with the Sub Chaser....

"You fellows have given me the longest and most exciting vacation from business that I ever had," he said, on leaving them at the Hampton ranch. "Little did I think I would be i...

They stood in the bow of the boat, which long since had rounded West Point and was proceeding very slowly along the southern shore of Santa Cruz Island. An hour and a half had e...

Jack asked the question at the breakfast table next morning. None of the four were seasick. At their homes on the far end of Long Island they maintained a speed boat. Bob and Fr...

While the others still sat where he had left them, regarding each other in speechless surprise, Inspector Burton returned, closed and locked the door, and resumed his chair as i...

They were finishing dinner at a famous restaurant. All about them were tables with gay little parties. The concealed orchestra was playing a popular air. Mr. Temple leaned back,...

A sound as of a vast drum being beaten, a drum bigger and more sonorous than anything ever conceived of, suddenly filled the salon. The walls seemed to quiver. So great was the...

Jack was highly excited as he dashed into the main salon and made for the door of the Temples' cabin. And with reason. He believed that now, if ever, they must attempt to seize...

The front wall of the little radio room was composed of stout wooden panelling to half a man's height from the floor with glass above. Mr. Temple, Bob and Jack knelt or crouched...

Frank slid down the rope which Mr. Temple, braced in the bow of the boat, held steady for him. Jack and Bob already were at the oars and fending off from the side of the trawler...

The old Chinaman, whose name they came later to know as Wong Ho and who was a very evil man with many ruffians at his command, was unconscious but breathing heavily. When Frank...

"Talk all ye please," said Murphy, "so long as I hear ye. But don't shout. An' don't try any funny business, because ye have no weapons, none of ye, while I an' my little Chinee...

"Well, boys," said Mr. Temple at breakfast next morning. "I'm going to be busy today talking business with my Pacific Coast representatives. First of all, however, Frank and I s...

As the door closed behind Murphy, Mr. Temple and the boys looked at each other with dismay written plainly on every countenance. They were to be taken to sea at once, and to an...

"Dad, we have got to see this thing through," declared Bob, turning toward Mr. Temple and voicing the desires of himself and his chums. "Surely, you won't put us aboard the Bear...

"Well, the batteries are heavy," said Jack. "The light poles weigh little, and the coil contains not much more than a pound of wire. But there are eight 'B' batteries of twenty-...

"Now, what is it, Frank?" asked Mr. Temple, when he and the three chums were all gathered in their staterooms with the door locked behind them. "What's all this mystery?"

Inspector Burton with difficulty repressed a smile at the inventor's childlike vanity. Mr. Temple experienced similar difficulty. Ensign Warwick grew red in the face, and the bo...

No signs of life were apparent as the glare of the searchlight played over the great building, resembling a dock shed in appearance, which bulked on shore at the end of the pier...

Mr. Temple beamed on the gathering in his sitting room at the Victoria Hotel. It was the afternoon of the following day. The party included the three chums and Inspector Burton....

As they gained the deck of the Sub Chaser they were confronted by a young ensign in the uniform of Uncle Sam's navy. He regarded them keenly, then offered his hand to Mr. Temple.

During the three-hour run east-southeast to Santa Barbara, which the Sub Chaser reached between two and three o'clock that afternoon, the fog lifted and the sun shone again, not...

The heavy iron door closed behind them with a slight grating sound. Jack turned his head. The door could not be distinguished from the wall. Hangings of thick silken stuffs cove...

"Where to, first?" queried Frank. "I vote for the Cliff House and Seal Rocks. Here in the guide book it says 'the seals play sportively in the restless tide.' And Sutro Baths ar...

"Well, you know more about radio than we. As far as I know, that light wasn't any indication that the radio was in use, because there is no such indication possible."

Murphy and the captured Chinese were bound and put aboard the boat. But first Robbins was apprised. "Black George" had not appeared yet. No time was wasted detaching the aerial....
