 him as we said good-by. Outside, Elaine and I got into the car again and moment later spun off, making little detour first through the eoun- try before hitting the shore road back again to Dodge Hill.
 
 On the rocky shore of the promon- tory several men were engaged in sinking a peculiar heavy disk which they submerged about ten or twelve feet. It seemed to be held by a cable, and to it wires were attached, appar- ently so that when key was pressed q circuit was closed.
 It was an "oscillator," new system for the employment of sound for sub marine signaling, using water instead of air as a medium to transmit sound waves. It was composed of a ring magnet, a copper tube lying in an air gap in magnetic field and a sta tionary central armature. The tube was attached to steel diaphragm. Really it was submarine bell which could be used for telegraphing or tel ephoning both ways through water
 The men finished executing the di- reetions of Del Mar and left, carefully eeneealing the land connections and key of the bell, while we were still at Del Mars.
 We had no sooner left, however, than one of the men who had been en- gagged in installing the submarine bell entered the library.
 'Well?" demanded Del Mar
 The bell is installed, sir" he said. Tt will be working soon."
 Good" nodded Del Mar.
 He went to a drawer and from it took a peculiar-looking helmet to which was attached a sort of harness fitting over the shoulders and carry. ing tank of oxygen The headpieee was a most weird eentrivanee, with what looked like huge glass eye in front. 1t was in reality a submarine life-saving apparatus.
 Del Mar put it on, all except the helmet, which he carried with him, and then, with his assistant, went out through the panel in the wall Through the underground passage the two greped their way, lighted by an cleo tric torch, until at last they came to the entrance hidden in the under brush, near the shore.
 Del Mar went over to the concealed station from which the submarine bell was sounded and pressed the key as a signal. Then he adjusted the subma- rine helmet to his head and deliber- ately waded out into the water, far ther and farther up to his head, then deeper still.
 As he disappeared into the water. his emissary turned and went back toward the shore road.
 
 The ride around through the coun- try and back to the shore road from Del Mars was pleasant. h fact, it was always pleasant to be with Elaine, especially in a car.
 Ne were spinning along at fast clip when We came to rocky part of the coast. As We made a turn a sharp breeze took off my hat and Whir1ed it far off the road and among the rocks of the shore. Elaine shut down the engine. with a laugh at me, and We left the car by the road while we climbed down the rocks after the hat
 It had been carried into the water, close to shore and, still laughing, we elambered over the rocks. Elaine in- sisted on getting it herself and in fact did get it. She was just about to hand it to me, when something bobbed She reached for it and fished it out It was cylinder with alright caps on both ends, in one of which Swas a hook
 What do you suppose it is?" she asked, looking it over as we made our way up the rocks again to the car Where did 1t come from?"
 We did not see man standing by our car, but he saw us It was Del Mars man who had paused on his way to watch us. AS we approached he hid on the other side of the road.
 By this time we had reached the car and opened the cylinder Inside was a note which read:
 "Chief arrived safely. Keep watch" ]"
 What does it mean?" repeated Elaine, mystified
 Neither of us could guess and I doubt whether we would have under stood any better, If we had seen a sinister face peering at us from be- hind rock near by, although doubt less the man knew what was in the tube and what it meant.
 We climbed into the car and start ed again. As we disappeared the man came from behind the rocks and ran quickly up tG the top of the hill There, from the bushes, he pulled out a peculiar instrument composed of a set up on tripod.
 Eagerly he placed the tripod, ad- justing the lenses and mirrors in the sunlight. Then he began working them. and 1t was apparent that he was flashing light beams, using Morse code. It was heliGgraph.
 Down the shore on the top of the next hill sat the man who had already given the signal with the handker- chief to those in the valley who were working on the mining of the bridge As he sat there. his eye caught the flash of the heliograph signal He sprang up and watched intently. Rap idly he jotted down the message that was being flashed in the sunlight:
 Dodge Girl has message from be- low. Coming in car. Blow first
