  • Scions of the choicest walnut trees growing in the forest had been grafted on to vigorous rootstock of black walnut, Juglans nigra, and planted out twenty feet apart in rows of half a dozen or so: Arcterek in the first row, Guardysky, Panfilovsky, Rodina, Bostandiksky, and the finest of them all, Uygursky, from the forest village of Gava.
