Nor was this all, for scores of the conveniences and even necessities of our modern life were unknown at the beginning of the nineteenth century. To get some idea of the vastness of the revolution in the conditions of living, we have but to remind ourselves that ``in the year 1800 no steamer ploughed the waters; no locomotive traversed an inch of soil; no photographic plate had ever been kissed by sunlight; no telephone had ever talked from town to town; steam had never driven mighty mills and electric currents had never been harnessed into telegraph and trolley wires.''[21] ``In all the land there was no power loom, no power press, no large manufactory in textiles, wood or iron, no canal. The possibilities of electricity in light, heat and power were unknown and unsuspected. The cotton gin had just begun its revolutionary work. Intercommunication was difficult, the postal service slow and costly, literature scanty and mostly of inferior quality.''[22] [21] The Rev. Dr. Theodore Cuyler. [22] Address of the Bishops of the M. E. Church, 1900. How marvellously the application of steam as a motive power has united once widely separated regions. So swiftly have the changes come and so quickly have we adapted ourselves to them that it is difficult to realize the magnitude of the transformation that has been achieved. We can ride from Pittsburg to Philadelphia in eight hours and to Calcutta in twenty-two days. The journey across our own continent is no longer marked by the ox-cart and the campfire and the bones of perished expeditions. It is simply a pleasant trip of less than a week, and in an emergency in August, 1903, Henry P. Lowe travelled from New York to Los Angeles, 3,241 miles, in seventy-three hours and twenty-one minutes. Populous states covered with a network of railway and telegraph lines invite the nations of the world to join them in celebrating at St. Louis the ``Purchase'' of a region which a hundred years ago was as foreign to the American people as the Philippines now are. The Rev. Dr. Calvin Mateer, who in 1863 was six months in reaching Chefoo, China, on a voyage from whose hardships his wife never fully recovered, returned in a comfortable journey of one month in 1902. To-day, for all practical purposes, China is nearer New York than California once was.
