“Oh, no! Here is a contrivance,” indicating a huge box-like affair, “with which I separate the oxygen from the hydrogen by electricity. Water, as you know, is composed of two gases—oxygen and hydrogen. Two atoms of hydrogen combined with one atom of oxygen and make a tiny bit of water. By the aid of this special device I segregate the two gases, use the oxygen and discharge the hydrogen overboard.”

“I’m going to take my hat off to you!” declared Jimmie. “But you had to have some means to prevent discomfort from the storage batteries!”

“Not with these!” smiled the other. “I’m using, without permission, of course, a new storage battery that does away with the lead-sulphuric acid type of battery. The inventor is a man whose name is familiar to you all. He uses a nickel, iron oxide and steel combination in a solution of potash. This battery, instead of causing inflammation or even proving deadly as is the case with the old type, is actually a benefit to a person. It is exactly opposite in its effect to the old style.”

“And you manage to make a cruise of days and days under water?”

“Surely!” smiled their host. “There’s nothing to prevent it!”

“That’s going some!” declared Jimmie. “But I don’t believe you managed to dig up a lot of gold from the bottom of the ocean!”

“What is there to hinder?” questioned the other.

“Everything!” declared Jimmie. “In the first place there is all the water about. Then, too, it would be easier to take this instrument into the regions where gold is usually discovered on land. You could prospect with it in almost the positive knowledge that you would locate a vein. Digging then would be easy.”

“Yes, but I don’t like to dig!” laughed the other. “Perhaps I’m too lazy to do that sort of thing!”

“There’s something queer here that I don’t quite get,” stated Jimmie. “Can’t you explain a little more in detail?”
