The two went softly up the hall stairs, through the long entry to the L, and into Elmer's room. They set the lamp on a table, and Elmer dragged forth from the scientific confusion of the place a collection of telegraphic apparatus of all kinds.
"There's the battery. That I'll keep here. There is the recording instrument. That I'll keep here also. Now you want a small armature to open and close the current. Wait a bit! I'd better make one."
Alma sat down on a box, and her new Lohengrin set to work with shears and file to make something that would answer for an armature and still be small enough to hide in the hand. Cutting off two small pieces of insulated copper wire, he bound them together side by side at one end. The loose ends he separated by crowding a bit of rubber between them, and then with the file and his knife he removed a part of the insulating covering till the bright copper showed at the tips of each wire.
"There! You can hide that in the pocket of your dress, or hold it in your hand even. When you wish to close the circuit, pinch the wires, and they will touch each other. When you withdraw the pressure the rubber will push them apart."
Alma declared she could do it easily, and the armature having been connected with the wires and the battery, they both prepared to go to the parlor.
Down the stairs they crept, slowly unwinding two delicate coils of insulated wire as they went, and pushing them back against the wall well out of sight. When they came to the mats Alma lifted them up, and Elmer laid the wires down, and then the mats covered them from sight.
"Now, you sit here, in a comfortable chair, and hide the wires in the folds of your dress. I'll lead them off over the carpet behind you, and unless the——Lawrence is brighter than I think he is, he'll not find them."
These mysterious operations were hardly completed before the door bell rang and Lawrence came in. He did not seem particularly pleased to find Mr. Franklin sitting up with Alma, and the meeting was not very cordial. After a few unimportant remarks Mr. Franklin said that he must retire.
"I'd like to know, miss, what that puppy said to you. He's been here all the evening, I dare say."
"He has, Lawrence; but I will not have my friends spoken of in that way."
