The attempt to continue the _Neue Rheinische Zeitung_ under the title _Neue Rheinische Revue_ had only the negative result of swallowing up Marx's last resources. How poor Marx then was can be judged from the fact that he had to send his last coat to the pawnshop in order that he might buy paper for his pamphlet on the Cologne Communist trial (towards the end of 1852). On top of all this, lamentable differences sprang up among the German exiles, who, deceived in their revolutionary illusions, overwhelmed one another with recriminations; an echo of these conflicts is heard in the pamphlet "Herr Vogt" (1860). Marx's only regular source of income in the years 1851-60 was his earnings as correspondent of the _New York Tribune_, which paid him at the rate of a sovereign per article, and this hardly covered his rent and the cost of newspapers and postage. Yet his articles were veritable essays, the fruit of researches which cost him a good deal of time. And in the midst of this penury the idea of writing a Socialistic criticism of political economy burnt within him. One might almost say that since 1845 this idea had allowed him no peace. Freiligrath's lines are, as it were, stamped upon him: In the clouds his goal he planted; In the dust had he to live, Bare existence daily granted. Cramped, hemmed in on every side, Pinched by poverty and urged By want, he, of all denied, By necessity was scourged. Only in the sixties did his fortunes improve. Small family inheritances, Wilhelm Wolff's legacy of over L800, and Engels' more plentiful and regular help, which from 1869 onward amounted to about L350 annually, enabled Marx to write his "Capital," the first volume of which, as is well known, is dedicated to Wilhelm Wolff.
