I next tried the effect of electrolytic action when iron salts were present, but did not think of using iron electrodes until after trying aluminum. I found that the action of non-oxidizable electrodes was most efficacious after the temperature of the fluid acted upon rose 4° or 5°; but the cost of working made it impossible on a large scale.
They were preparing to carry out a seat-ejection experiment. We observed a round object, white aluminum color, which at first resembled a parachute canopy. Our first impression was that a premature ejection of the seat and dummy had occurred but this was not the case.
When it boils, the rice and tallow must be added, and when the rice has boiled twenty minutes the whole is set aside to cool. Meanwhile the two aluminum pots full of snow, replenished from time to time as it melts, are put upon the stove in the tent as the necessary preliminary to cooking. Sometimes ice, and more rarely water, may be had, and then supper is hastened.
In what appeared to be a great park, the anchor was dropped into the top of a tree. It held securely, and Will and Denison descended in the cage and made a very strong aluminum cable fast about the trunk of the tree. After all was made secure, Dr. Jones and Professor Gray also descended. The little company then began looking around for signs of life.
In this State large aluminum works have been constructed and the quantity of precious and semiprecious stones found there is a large part of the production for the United States. The tobacco industry is growing rapidly in the South. There have always been small establishments for the manufacture of tobacco, and many of these during the last three decades have grown to large proportions.
Of these the Vickers machine used mainly by the British is a common type. It is built throughout of steel and aluminum, and the entire fusillage is clothed with steel plating which assures protection to the two occupants from either upward or lateral fire. The sides of the body are carried up so that only the heads of the aviators are visible.
"Then, Doctor, if money be any object to you, you shall have your own price for remaining until you pronounce her well." "I am extremely sorry, Count, but that cannot be. My Government has built yonder aluminum air-ship at enormous expense at my express desire and instigation, with the understanding that I sail with it to the North Pole. My obligation is to do so with all possible dispatch.
"That's a pretty big order, isn't it, Dick? How are you going to handle it, or even get it into your apparatus?" "Easily enough as far as getting the sample goes. I have already had some sample bottles made. I have one of them in the lab excuse me a moment." Arcot left the room, to return a few minutes later with a large aluminum bottle, tightly closed.
It was of the type so constructed that the two rear seats of the car may be dropped off at will, converting it into a carriage for two, and the only peculiar detail I noted was the odd-looking top or canopy. "Well, what do you think of her?" demanded Hawkins with some pride. "She's all right," I said, admiringly. "Body's built of aluminum," continued the inventor.
Then suddenly he knew the truth; and with a cry of fear bent, peering at the fuel-tank. There, quivering suspended from the metal edge of the aluminum tank, hung a single clear white drop alcohol! Even as Stern looked it fell, and at once another took its place, and was shaken off only to be succeeded by a third, a fourth, a fifth! The man understood.
