Sparks, as a rule, are looked upon as a race of useless and disreputable fellows. Their course is usually erratic¹. They fly upward, downward, forward, and backward—here, there, and everywhere. You never know when you have them, or what will be their next flight. They often create a good deal of alarm, sometimes much surprise; they seldom do any good, and frequently cause irreparable damage. Only when caught and restrained, or directed, do sparks become harmless and helpful.

 

But there is one Spark in this world—a grand, glowing, gushing² fellow—who has not his equal anywhere. He is old as the hills—perhaps older—and wide as the world—perchance wider. Similar to ordinary sparks in some respects, he differs from them in several important particulars. Like many, he is “fast,” but immeasurably faster than all other sparks put together. Unlike them, however, he submits to be led by master minds. Stronger than Hercules, he can rend³ the mountains. Fleeter than Mercury, he can outstrip⁴ the light. Gentler than Zephyr⁵, he can assume the condition of a current, and enter our very marrow⁶ without causing pain. His name is Electricity. No one knows what he is. Some philosophers have said that he is a fluid, because he flows. As well might they call him a wild horse because he bolts, or a thief because he lurks⁷! We prefer to call him a Spark, because in that form only is he visible—at least when handled by man.

 

Talking of that, it was not until the last century that master minds found out how to catch and handle our Spark. In all the previous centuries he had been roaming gaily⁸ about the world in perfect freedom; sometimes gliding
