EXPLANATION OF PLATE XXIII. 
The results of the cylinder experiments are here graphically shown. 
The depths of the root growth and the heights of the shoot develop¬ 
ment are drawn to a scale with reference to the surface of the soil 
and to the water level. In plots 1 and 2 the results for each species 
are grouped together. In plot 3 the relative development of the 
four species in each cylinder is shown in succession.
