Eric perceived that Roland had heard the last remark notwithstanding the low tone, and said in a jesting way, that a man who has to deal with the nervous filaments extended over the earth might very readily become nervous himself.
The telegraphist assented, and had many wonderful stories to tell. When Eric went with Roland into the passenger's room, he was surprised to see Roland's quick eye for the laughable characteristics of people. He had observed very shrewdly the peculiarities of the telegraphist, and imitated him very exactly. Without a direct rebuff, Eric endeavored to explain to his pupil, that those persons who are partly engaged in work, and partly in science, in that middle region of the vocations of life, such as apothecaries, surgical operators, lithographists, photographists, and telegraphists, are easily carried from one extreme to the other. Telegraphy created a certain excitability, and susceptibility, on account of the direct arousing of the faculties and the operation at great distances, which give to the soul a certain tension and excitation.
Eric sought to explain all this to his pupil; he would have liked to give him the just views which are embraced in the knowledge of psychological principles, but he led him back to the wonderful in what they had seen, and he succeeded in his purpose of deeply impressing this upon the soul.
The stars were glittering in the heavens, when they returned home from their glance into the mysterious primitive force of earth's being.
Eric could not restrain the impulse to picture to his scholar what had been probably the feelings of that people of the desert, on the evening of that day when Jehovah had revealed himself to them in thunder and lightning upon Mount Sinai; how it must have been with them when they went to rest, and how it must have seemed to the souls of thousands, as if the world were created anew.
Eric hardly knew what he was saying, as he drove through the refreshed and glistening starry night. But the feelings of the boy and the man were devotional. And after they reached home neither wished to speak one word, and they quietly bade each other good-night. But Eric could not go to sleep for a long time. Is the light in the soul of a human being an incomprehensible electric spark that cannot be laid hold of, and which flashes up in resolve and act? So long as there is no storm in the sky we send at will the spark over the extended wire; but when the great, eternally unsubdued, primitive forces of nature manifest themselves, the human message is no longer transmitted, and the sparks spontaneously play upon the conducting wires. Chaos sends forth an unintelligible message.
A time will come when thou shalt no longer be master of the living soul of thy pupil, in which, with all thy heedful precaution, rude, uncontrolled elements are at work. What then?
There is no security given for the whole future, and in the meantime, what concerns us is to fulfil quietly and faithfully the duty of the day.
