Grouih of Red Clover by diffcicnt, Jliiiiiii es. 
189 
The produce, after the heavy dressing of mineral manure upon 
tlic removal of the first rutting, is seen to be, in every case, small. 
In only two instances is it equal to more than a ton of hay per 
acre, n;unely, on Plot 4, Series 1 and 2 ; that is, where sulphate 
of potash and superphosphate of lime were applied. In all the Sc- 
ries, however, the efl'ect of the potash, and of the potash and phos- 
phate together, is more or less marked. In fact, notwithstanding 
tliat this was the third season of Clover in four years, the produce 
with these manures, taking the two cuttings of 1852 together, was, 
in several cases, equal to from 2i to o tons of hay per acre. 
A good deal of the plant stood tolerably well during the winter 
of 1852-3, but almost all died off in the spring. The land was 
therefore ploughed up, and fresh Red Clover-seed drilled in 
April, in rows 20 inches apart, in order to admit of the use of 
the horse-hoe. The plant came up very Aveak ; there was no 
crop worth cutting in the autumn ; and nearly the whole died 
off" during the winter of 1853-4. 
In the spring of 1854, the land Avas again ploughed up, and 
allowed to remain fallow until September. The whole piece 
consisted of 15 " lands," each 13 feet 3 inches wide, divided 
into 6 lengths, forming the 6 " Plots " numbered from 1 to 6 respec- 
tivelv, in the Tables. It Avas noAV divided into three Avidths onh', 
of 5 lands each, represented in subsequent Tables as Series 1, 2, 
and 3.* One of these (Series 1), the whole length of the 6 plots 
of course, Avas left unmanured ; the second (Series 2) Avas manured 
Avith 20 tons of farmyard manure doAvn the whole length of the 
G plots ; and the third (Series 3), also throughout the G plots, Avas 
manured Avith 20 tons of farmyard manure, and 5000 lbs. of 
freshly burnt lime, per acre. These Avere ploughed in on Septem- 
ber 25, 1854, and CloA'er-seed Avas drilled on October 10. Plants 
just came up, but all died off" during the Avinter of 1854-5. 
Clover-seed Avas again drilled on April 14, 1855, at the rate 
of 20 lbs. per acre, Avithout further manure. The folloAving 
Table (V.) shoAvs the manures applied in 1854, and the produce 
of Clover obtained in September, 1855, Avithout manure since 
1854, but after a second and heaA'y sowing of seed. 
* The Plots designated in Tables III. and IV. as Series 1, 2, and 3, consisted 
of four lands each ; and those as Series 4, of three lands, each running the length 
of the six Plots which had either no mineral manure, or one of the five different 
descriptions enumerated in the Tables. Under tlie new arrangement. Series 1 
(now to be unmanured) includes the four lands of the former Series 1, which 
from the beginning were manured with mineral manures only, and one land of 
the former Series 2, -which had the dung and lime applied in 1851 ; Series 2 (now 
to be manured with farmyard manure alone) includes the remaining three lands of 
the former Series 2, and two lands of the former Series 3, which, besides the 
several dressings of mineral manures, was manured in 1849 with ammonia salts; 
and Series 3 (now to receive farmyard manure and freshly burnt lime") includes 
the two remaining lands of the former Series 3, and the three lands of the former 
Series 4, which latter (besides the mineral manures as specified) were manured 
with rape-cake in 1S49, and with soot, lime, &c. ii; 1851.
