"We follow the scientists around and look over their shoulders. They're watching their feet: provable mistakes are bad for them. We're looking as far ahead as we can, and we don't get penalized for mistakes."

| Electric Protection-Wires (Electrified Fence) | ||
| An electric fence. |
| Adjusting the electric protection-wires that were to paralyze any creature that attempted to come within the circle, and would arouse them by ringing a bell, he knocked the ashes from his pipe, rolled himself in a blanket, and was soon asleep beside his friends. |

Another excerpt:
As far as I know, the first instance of the idea of an electrified fence or railing occurs in Jules Verne's 20,000 Leagues Under the Sea.
Arranging a double line of electric wires in a circle about the mastodon and themselves, they sat down and did justice to the meal, with appetites that might have dismayed the waiting throng. Whenever a snake's head came in contact with one wire, while his tail touched the other, he gave a spasmodic leap and fell back dead. If he happened to fall across the wires, he immediately began to sizzle, a cloud of smoke arose, and lie was reduced to ashes.
