vi. Bromus mollis. 
- Box 1. Plant c^espitose. Pibres numerous, vertical, wiry, 8- 
10 inches long, not much branched, but thickly covered with root^ 
hairs. 
Box 2. Same general characters as 1, but fibres denser, longer, 
12-14 inches long ; root-hairs more numerous, root-development 
altogether superior. 
Box 3. Eoot- development scarcely, if at all, superior to 1. 
Box 4. But little better than 3 ; fibres rather longer, 10- 
12 inches long ; root-hairs slightly more abundant. 
Box 5. Better than 4. Main fibres 8 inches long, but stouter 
than in 4. 
Box 6. Main fibres 8-10 inches long, nearly the same as 3 ; 
densely covered with root-hairs ; 3 and 6 nearly alike. 
"When compared with the condition of the plant in October, 
some remarkable difierences were observable. Thus, in box 2 
(mineral manures), the roots were highly developed, while the 
plant was but slightly so. In box 4 (nitrate of soda) the reverse 
conditions were noticeable, viz. low root-condition, high plant-de- 
velopment. In 6 (min. and nitrate) the appearances were similar 
to those in 4, but less pronounced. 
The condition of the root and plant respectively may be thus 
indicated : —

vii. Trifoliim jpratense. 
Box. 1. Plant tufted (uniform). Eoot tap-shaped, woody, 10- 
12 inches long, ^ inch in diameter ; fibres numerous (especially 
towards the upper and central portions of the root), wavy, di- 
rected obliquely downwards. 
Box 2. Yariable. Plant more "stocky" than in no. 1, i.e. 
stock more branched, and the branches of a firmer texture. Tap-
