This lifelong fixed interest in agricultural settlement of the Land of Israel became Ussishkin’s duty in 1923, as president of the Keren Kayemet, the Jewish National Fund. Until his death, eighteen years later, the Keren Kayemet, under his guidance, raised large sums of money and bought large tracts of land in Israel, now teeming with life.
