There was, however, a still brighter illuminant within their reach in the shape of acetylene, but not until it became certain that they would have to spend a second winter in the Antarctic, did their thoughts fly to the calcium carbide which had been provided for the hut, and which they had not previously thought of using.
"Why," I said, "I didn't know you had an acetylene plant." "No more have I, Homer." "But what is that, then?" I demanded. "It's my invention," he returned proudly. "I've been workin' on it two years, Homer, and only got it goin' yestiddy. It's going to be a great thing, I tell you." "But what is it, Sam?" "It's gas from crude petroleum, Homer.
But these efforts scarcely took more time than the telling, and when the powerful streak of light finally pierced the darkness the very first thing it showed us was a white sail. "I shouldn't have worried about night catching us, sir, if I'd thought of this before," Gates laughed. "And there's plenty of extra acetylene tanks, too, so she carn't get away now!"
We arrived, cold and uncomfortable, in two saloon cars, the second one holding several long cylinders similar to the oxygen or acetylene tanks commonly used in American industry. There was a great deal of mysterious consultation between Miss Francis and her assistants, punctuated by ritualistic samplings of the vegetation and soil.
Thomson attempted to separate and determine the quantity of carbon monoxide and hydrocarbons present in the flue gases from various forms of gas stoves and burners, but, like every other observer who has attempted to solve this most difficult problem, he found it so beset with difficulties that he had to abandon it, and contented himself with determining the total amounts of carbon and hydrogen escaping in an unburned condition, experiments which showed that the combustion of gas in stoves for heating purposes is much more incomplete than one had been in the habit of supposing, but his experiments give no clew as to whether the incompletely burned matter consisted of such deleterious gases as carbon monoxide and acetylene, or comparatively harmless gases, such as marsh gas and hydrogen.
In that tank is a porous asbestos packing saturated with acetone, under pressure. Thus they carry acetylene safely, for it is dissolved and the possibility of explosion is minimized. "This mixing chamber, by which I am holding the torch, where the oxygen and acetylene mix, is also designed in such a way as to prevent a flash-back.
I know your game the water forms acetylene with the carbon, and that uniting with the nitrogen of the air under the terrific heat of the electric arc forms hydrocyanic acid. Would you poison us, too? Do you think you can put me unconscious out on the street and have a society doctor diagnose my case as pneumonia?
However, I shrewdly suspect that, even if this story is true, they are using hydrogen or acetylene flares over there. But none of these things would be feasible in your case. You'd know it." "Could it be some one who is projecting a deadly wireless force which causes the explosions?" I put in, mindful of a previous case of Kennedy's.
Even if she had wished it, she could not have asked questions now. It was midnight when Nevill's car ran into the beautiful oasis town, guarded by the most curious mountains of the Algerian desert, and they were at their strangest, cut out clear as the painted mountains of stage scenery, in the light of the great acetylene lamps.
They were much worried, more than they cared to admit to each other. The meal over, Giant warmed some water and washed the few tin dishes and other things which had been dirtied. Snap put another log on the fire, and then got out the acetylene bicycle lamp that had been brought along. "What are you going to do with that?" questioned Giant.
