The above are only a few of the directions of the century's progress. In some we may name, the development has been more extraordinary still. Let us consider the remarkable advance in methods of travel. In the year 1800, as for hundreds and even thousands of years before, the horse was the fastest means known of traveling by land, the sail of traveling by sea. A hundred years more have passed over our heads, and what do we behold? On all sides the powerful, and swift locomotive, well named the iron-horse, rushes onward, bound for the ends of the earth, hauling men and goods to right and left with a speed and strength that would have seemed magical to our forefathers. On the ocean the steam engine performs the same service, carrying great ships across the Atlantic in less than a week, and laughing at the puny efforts of the sail. The horse, for ages indispensable to man, is threatened with banishment. Electric power has been added to that of steam. The automobile carriage is coming to take the place of the horse carriage. The steam plough is replacing the horse plough. The time seems approaching when the horse will cease to be seen in our streets, and may be relegated to the zoological garden. In the conveyance of news the development is more like magic than fact. A century ago news could not be transported faster than the horse could run or the ship could sail. Now the words of men can be carried through space faster than one can breathe. By the aid of the telephone a man can speak to his friend a thousand miles away. And with the phonograph we can, as it were, bottle up speech, to be spoken, if desired, a thousand years in the future. Had we whispered those things to our forefathers of a century past we should have been set down as wild romancers or insane fools, but now they seem like every-day news. These are by no means all the marvels of the century. At its beginning the constitution of the atmosphere had been recently discovered. In the preceding period it was merely known as a mysterious gas called air. To-day we can carry this air about in buckets like so much water, or freeze it into a solid like ice. In its gaseous state it has long been used as the power to move ships and windmills. In its liquid state it may also soon become a leading source of power, and in a measure replace steam, the great power of the century before. [=Education, Discovery and Commerce=]
