The same remarks will apply to these analyses as to those of 
sainfoin. The composition of the ash is evidently but little 
altered by the presence of the seed^ probably because it is small 
in cjuantity. 
It is seen that Italian rye-grass is, like other cereals, a silicious 
plant, and, indeed, in the quantity of silica which it removes from 
the soil it surpasses even wheat-straw, which, it will be remem- 
bered, contains about 60 lbs. in every ton weight. 
Where, therefore, the use of liquid manure is able to produce 
many successive luxuriant crops of this plant, there can be no want 
of available silica in the soil for any crops. 
//o/w. — The following are analyses of three specimens of the 
flower of hops : — 
Specimen No. 1. — Bentley hops grown by Mr. Samuel Eggar 
on a deep rich soil resting on the grey marl rock ; manured in 
1847 with farm manure and woollen rags. The hops were 
gathered in the second week of September, 1847. Produce 5 
cwt. per acre. 
Specimen No. 2. — GolJing hops from Mr. J. M. Paine of 
Farnham. This specimen was grown on land that has been in 
cultivation as hop-ground for more than 100 years, highly ma- 
nured every year; the manure in 1847 was guano and woollen
