By this time you will have gained a fair idea of Rob's character. He is, in truth, a typical American boy, possessing an average intelligence not yet regulated by the balance-wheel of experience. The mysteries of electricity were so attractive to his eager nature that he had devoted considerable time and some study to electrical experiment; but his study was the superficial kind that seeks to master only such details as may be required at the moment. Moreover, he was full of boyish recklessness and irresponsibility and therefore difficult to impress with the dignity of science and the gravity of human existence.

They were his nearest and dearest friends on earth, and in his boyish heart he loved them all and believed in their goodness and sincerity. The possibility of finding a bad character mark on any of their familiar faces made him shudder, and he determined then and there never to use the spectacles to view the face of a friend or relative.
