This volume of the Weizmann Letters covers a period of two years and nine months, from the 13th Zionist Congress at Carlsbad in August 1923 until Chaim Weizmann's departure from London for a visit to Palestine in March 1926. These were years of reorientation in the history of Zionism, with its center of gravity shifting from the political sphere to the task of construction in Palestine. The transition was bound to involve difficulties for the movement, for political work, with its immediate challenges, would naturally be more appealing than the practical work in Palestine, which was gradualist, and only bore fruit after a considerable lapse of time.
