Soon after the outbreak of the war, the Zionist leaders in England had attempted to come to an understanding with those indifferent to their cause and with the so-called anti-Zionists, in order to render possible, without renouncing the principles of Zionism, collaboration in working out a practical scheme in Palestine. All these motives led the leaders of English Zionism to request the general organization to delegate here two of their representatives ――namely, Dr. Tschlenow of Moscow and the author, for the purpose of assisting in the important work to be done in this country. They arrived in London shortly before the end of the year 1914. Space does not allow us to describe the work of these three years in detail; we must therefore confine our attention to the chief features. In the course of the first few months the work consisted in a searching test of the attempts in hand: this test yielded a perfect agreement and a verification of all reports made. In the early months of 1915 there were new conferences with many leading personalities, with favourable results. In March, 1915, Dr. Tschlenow, Dr. Weizmann, and the author went to Paris, after Dr. Weizmann had previously visited Paris again and again on Zionist business. Attention was then confined to Jewish circles, and so far as non-Jewish circles were concerned a certain general enquiry appeared to be necessary. At the same time, attempts were made through conferences with a group of leading Jewish personalities in London who stood aloof from Zionism, to bring about an understanding. The Zionist delegation which was in charge of these negotiations and this correspondence was composed of Dr. E. W. Tschlenow, Dr. Moses Gaster, Mr. Joseph Cowen, Mr. Herbert Bentwich, and the author. As an understanding just then appeared impossible, the negotiations were postponed until further notice. Dr. Tschlenow shortly afterwards left England, after a stay of five to six months, and returned to Russia. At the meeting of the Zionist Committee in Copenhagen and at the Zionist meetings that took place in Russia, Dr. Tschlenow was able to report that the political efforts in England had filled him with the best hopes. The Author remained in England and devoted himself, in addition to propaganda, to the political task in which Weizmann’s unwearied efforts became more and more important. The period 1915‒1916 was more one of preparation than one of execution: Zionism had to be strengthened from within, the societies in London and the Provinces had to be maintained, new societies had to be created, pamphlets and books had to be written and published; externally, the work consisted in finding new sympathisers, and in an enlightening propaganda wherever a proper opportunity offered itself. The correspondence with the Zionist leaders and organizations in Russia and America became more active and the relations ever closer. In London a number of talented young Zionist writers and workers had grouped
