And to think of this great country in danger of being dominated by people ignorant enough to take a few ancient Babylonian legends as the canons of modern culture. Our scientific men are paying for their failure to speak out earlier. There is no use now talking evolution to these people. Their ears are stuffed with Genesis.

Bryan - a great friend of mine, by the way - had a Neanderthal type of head, Burbank says. As to Riley, he has not even the oratorical skill of Bryan. The whole movement is based on the poor whites of the south.

I have seen myself lose intolerance, narrowness, bigotry, complacence, pride and a whole bushel-basket of other intellectual vices through my contact with Nature and with men. And when you take weeds out of a garden it gives you room to grow flowers.
