MORE DIAGRAMS FROM STOUTS ROOT STUDIES As explained in the text on p. 40, Professor Ben Stout of Rutgers showed, by exposing and tracing out 25 forest trees' root systems, that the latter reached into areas 3.4 to 40.7 times as great as the ground-space under their crowns. In Mr. Stout's diagrams on this and the next page, dotted lines show crown areas, solid lines the major roots. Graphs give stem (—0—) and root (—x—) growth data in feet and years.
