political party, and that they should have remained a purely economic one. Besides, he looked on it as mere folly to expect, with Lassalle, the accomplishment in thirty years of changes which, as we have seen, he believed five centuries little enough time to evolve. Rodbertus may thus be said to have had some relations with the present movement, but Marlo stands completely apart from it: and his large and important work, "Untersuchungen über die Organization der Arbeit, oder System der Weltökonomie," published at Kassel in 1850-5--though original, learned, and lucid--remained so absolutely unknown that none of the lexicons mention his name, and even an economist like Schaeffle--who was the first to draw public attention to it, and has evidently been considerably influenced by it himself--had never read it till he was writing his own work on socialism (1870). But though Marlo cannot be said to have contributed in any respect to the present socialistic movement, his work deserves attentive consideration as a plea for fundamental social reform, advanced by a detached and independent thinker, who has given years of patient study to the phenomena of modern economic life, and holds them to indicate the presence of a deep-seated and widespread social disease. Carl Marlo is the _nom de plume_ of a German professor of chemistry named Winkelblech, and he gives us in the preface to his second volume a touching account of how he came to apply himself to social questions. In 1843 he made a tour of investigation through Northern Europe in connection with a technological work he was engaged in writing, and visited among other places the blue factory of Modum, in Norway, where he remained some days, charmed with the scenery, which he thought equal to that of the finest valleys of the Alps. One morning he went up to a neighbouring height, whence he could see the whole valley, and was calmly enjoying the view when a German artisan came to ask him to undertake some commission to friends in the fatherland. They engaged in conversation. The artisan went over his experiences, and repeated all the privations he and his fellows had to endure. His tale of sorrow, so alien apparently to the ravishing beauty around, made a profound impression on Winkelblech, and altered the purpose and work of his life. "What is the reason," he asked himself, "that the paradise before my eyes conceals so much misery? Is nature the source of all this suffering, or is it man that is to blame for it? I had before, like so many men of science, looked, while in workshops, only on the forges and the machinery, not on the men--on the products of human industry, and not on the producers, and I was quite a stranger to this great empire of misery that lies at the foundation of our boasted civilization. The touching words of the artisan made me feel the nullity of my scientific work and life in its whole extent, and from that moment I resolved to make the sufferings of
