This post is not genealogy-related, but fellow ERB fans will definitely appreciate it-- free download of this center of the Earth tale by ERB is available at Project Gutenberg:
NOTE: Yes, I know ERB is not the best prose stylist ever, but people read his books way back when (and continue to read them) because they are FUN to read…
NOTE NO. 2: BTW, since we're talking about the center of the earth, my wife and I both saw the Journey to the Center of the Earth 3-D movie recently. It was great fun, and the 3-D effects were generally VERY well done!
