As the Chester express steams out of Shrewsbury station, you see on your left, overhanging the steep bank of Severn, a large, square, substantial-looking house, known as the Mount, the birthplace of the author of the 'Origin of Species.' There, in the comfortable home he had built for himself, Dr. Robert Darwin, the father, lived and worked for fifty years of unobtrusive usefulness. He had studied medicine at Edinburgh and Leyden, and had even travelled a little in Germany, before he settled down in the quiet old Salopian town, where for half a century his portly figure and yellow chaise were familiar objects of the country-side for miles around. Among a literary society which included Coleridge's friends, the Tayleurs, and where Hazlitt listened with delight to the great poet's 'music of the spheres,' in High Street Unitarian Chapel, the Mount kept up with becoming dignity the family traditions of the Darwins and the Wedgwoods as a local centre of sweetness and light. On February the 12th, 1809, Charles Darwin first saw the light of day in this his father's house at Shrewsbury. Time and place were both propitious. Born in a cultivated scientific family, surrounded from his birth by elevating influences, and secured beforehand from the cramping necessity of earning his own livelihood by his own exertions, the boy was destined to grow up to full maturity in the twenty-one years of slow development that immediately preceded the passing of the first Reform Act. The thunder of the great European upheaval had grown silent at Waterloo when he was barely six years old, and his boyhood was passed amid country sights and sounds during that long period of reconstruction and assimilation which followed the fierce volcanic outburst of the French Revolution. Happy in the opportunity of his birth, he came upon the world eight years after the first publication of Lamarck's remarkable speculations, and for the first twenty-two years of his life he was actually the far younger contemporary of the great French evolutionary philosopher. Eleven years before his arrival upon the scene Malthus had set forth his 'Principle of Population.' Charles Darwin thus entered upon a stage well prepared for him, and he entered it with an idiosyncrasy exactly adapted for making the best of the situation. The soil had been thoroughly turned and dressed beforehand: Charles Darwin's seed had only to fall upon it in order to spring up and bear fruit a hundredfold, in every field of science or speculation. For it was not biology alone that he was foredoomed to revolutionise, but the whole range of human thought, and perhaps even ultimately of human action.
