It may have been fanciful, but I could not help feeling a breath of home, as from a flap or flutter of St. George's Cross, when I first sat down in a Canadian hostelry, and read the announcement that no such telephonic or other summonses were allowed in the dining-room.
Now listen in for telegraphic signals or telephonic speech or music; when you hear one or the other slide the secondary coil in and out of the primary coil until the sounds are loudest; now move the contact switch over the points forth and back until the sounds are still louder, then move the slider to and fro until the sounds are yet louder and, finally, turn the knob of the condenser until the sounds are clear and crisp.
When Tom perfected his photo telephone the last objection to rendering telephonic conversation admissible evidence in a law court was done away with, for by this invention a person was able to see, as well as to hear, over the telephone wire. One practically stood face to face with the person, miles away, to whom one was talking.
The stamp of a horse in a stall, the low, throaty notes of a cow nuzzling her calf, the far-off evening wail of a coyote all seemed strangely near at hand, borne by some telephonic quality in the atmosphere. "How still it is!" said Clyde. "One can almost feel the darkness descending." "Electrical storm coming, I fancy. No such luck as rain."
Reis himself does not appear to have been sufficiently interested in the marvellous possibilities of the idea to follow it up remarking to the man who bought his telephonic instruments and tools that he had shown the world the way. In reality it was not the way, although a monument erected to his memory at Frankfort styles him the inventor of the telephone.
Here also were the magnetic-anchor release and the air-skid pump control; here were telephonic connections with the wireless-room and with the fore-and-aft observation pits, where observers were already lying on their cushions upon the heavy, metal-reinforced glass floor-plates. "This is really very complete," approved the Master. Not Alden, but he, had been first to speak.
Inside the headpiece of each of the electrical suits was the mouthpiece of a telephone. This was connected to a wire which, when not in use, could be conveniently coiled upon the arm of the wearer. Near the ears, similarly connected with wires, were telephonic receivers.
By making E an electro-magnet, and including its coil in the telephonic circuit, an instrument may be constructed in which the normal pressure between the electrodes can be automatically adjusted to the strength of the current, and in cases where an induction coil is employed the magnet, E, may be the core of such a coil.
Field telegraph lines were established and maintained under the enemy's fire at Manila, and later the Manila-Hongkong cable was reopened. In Puerto Rico cable communications were opened over a discontinued route, and on land the headquarters of the commanding officer was kept in telegraphic or telephonic communication with the division commanders on four different lines of operations.
Its operations during the war covered the electrical connection of all coast fortifications, the establishment of telephonic and telegraphic facilities for the camps at Manila, Santiago, and in Puerto Rico. There were constructed 300 miles of line at ten great camps, thus facilitating military movements from those points in a manner heretofore unknown in military administration.
