two seasons. In the unmanured box, last year fhe root was 
lowest in point of development, in this season highest, some of 
the roots measuring 2| feet. On the other hand, the roots in 
box 2 (mineral manure) last year were very high, in this year 
they were very poorly developed. A precisely similar remark 
holds good in the case of box 3. In box 4 the discrepancy is 
not so great ; this season the roots in this box measured two feet 
and upwards in length.

In the unmanured box the plants generally were of compara- 
tively feeble development, improving materially in this respect 
about midsummer, and retaining the same position after the first 
cutting, but showing little vigour after the second cutting. 
Mineral manures had but slight effect at first ; but after the
