Frank Reade Jr. was one of the most popular fictional heroes in the dime novel pantheon. Like his father, Frank Jr. was an inventor; stories typically feature the young genius inventing a fantastic, technological marvel that leads him on dangerous adventures around the world.
In Boys of New York(April 23, 1887), Frank Jr. invents an "Electric Horse" to hunt for lost treasure in Peru. The horse has electronic torpedoes for blasting, gun rifles on either side, and travels up to thirty-five miles per hour. Accompanying Reade on his journey are Barney and Pomp, two servants who help operate the weapons by firing on those who interfere with Reade's treasure hunt.
