Predictions range far and wide.
The people of the Earth will be in close communication with Mars by being shot off in great cannons. A glorious prospect spreads before us fortified by every incentive to further progress and discovery. And he who lives to scan the Twentieth century as it merges into the Twenty-first may look back with as startling comparisons as we now employ in speaking of the Nineteenth. This year, too, a lively discussion is in progress about when we should celebrate the beginning of the twentieth century. The book offers many historic images from the Society's vast visual materials collections.
