"Because of the terrific winds that almost continually sweep over that part of Siberia. They never seem to cease, and there are treacherous air currents and 'pockets' that engulfed more than one luckless aviator. Oh, you may be sure the Russian government spared no means of finding the lost platinum mine, but they could not locate it, or even get near the place where they supposed it to be.
"Then, perhaps thinking that my brother and I were concealing something, they separated us. Where they sent him I do not know, but I was doomed to the sulphur mines. I was heartbroken, and I scarcely cared whether I lived or died. But an opportunity of escape came, and I took it. I wanted to save my brother, but I did not know where he was, and I thought if I could make my way to some civilized country, or to free America, I might later be able to save my brother.
"I went to England, taking some of my precious platinum with me, and stayed there for two years. I learned your language, but my efforts to organize an expedition to search for the lost mine, and for my brother, failed. Then I came here, and—well, I am still trying."
"My! That is certainly interesting!" exclaimed Ned, who had been all attention during the telling of the story.
"And you certainly had a hard time," declared Tom. "I am much obliged for this platinum. Have you set a price on it? It is worth much more than the ordinary kind."
"The price is nothing to you," replied the Russian, with a smile. "I am only too glad to help you fix your aeroplane. Will it take long? I should like to watch you."
"Come along," invited Tom. "I can soon have it going again, and I'll give you a ride, if you like."
"No, thank you, I'm hardly up to that yet, though I may be some day. The machine I made never flew well and I had several bad falls."
Tom and Ned worked rapidly on the magneto, and soon had replaced the defective bits of platinum.
"If the Russians had such a machine as this maybe they could have gotten to that mine," suggested Ned, who was very proud of Tom's craft.
