Field Experiments on Clovcr-Sceds 
Plot 5. No Manure. — Appearance of plant much like that on 
the preceding plot. 
Plot 6, Muriate of Potash, — The clover on this plot was very 
good both as regards colour and vigour of growth, and the rye- 
grass also was strong and of good quality. 
Plot 7. Sulphate of Potash. — Clover good, but rye-grass weak. 
Plot 8. Sulphate of Lime. — Rye-grass very thin and unhealthy 
in appearance ; the worst piece of the eleven experimental plots. 
Plot 9. Nitrate of Soda and Superphosphate. — Clover-plant 
quite smothered by rye-grass, which grew very long and coarse, 
and of quality little better than good oat-straw. 
Plot 10. Superphosphate and Muriate of Potash. — Decidedly 
the best plot ; clover remarkably strong, with a good broad leaf 
of a dark green colour. Rye-grass also very vigorous and of 
excellent quality. 
Plot 11. No Manure. — About the same as plots 3, 4, and 5. 
Second Cutting. 
Plot 1. There was scarcely any clover in the second cutting, 
and rye-grass also was very thin and weak. 
Plot 2. Clover very weak ; rye-grass much better than on the 
preceding plot, though short. 
Plot 3. Much the same as plot 2 ; rye-grass not quite so strong. 
Plot 4. Rye-grass and clover short and weak. 
Plot 5. Clover fair ; rye-grass short. 
Plot 6. Rye-grass good ; clover-leaves broad and of a good 
colour. 
Plot 7. Clover good ; but rye-grass weak and thin. 
Plot 8. The produce on plot 8 small and weak. 
Plot 9. Merely a few plants of clover were left on plot 9 after 
the first cutting, and the rye-grass was very thin and weak ; the 
soil appearing to have been quite exhausted by the first cutting. 
Plot 10. Clover very good, with a good broad and dark- 
coloured leaf; the rye-grass also strong and healthy. By far the 
best plot. 
Plot 11. Much the same as 4 and 5. 
We owe to Messrs. Lawes and Gilbert a series of most valuable 
and instructive field-experiments on the influence of different fer- 
tilising matters on the quantity and quality of the produce of 
permanent pastures. The changes which several of the fertilisers 
employed by Messrs. Lawes and Gilbert produced in the character 
of the herbage of several of their experimental plots are so in- 
structive, that for some years past I have made it a point to pay 
a visit to Rothamsted Park at the time when the grass-crop is in 
the height of perfection. Having frequently seen with my own
