XXXIX. — On the Double Culture of Tur nips between Peas. By 
Charles Hannam. 
To Mr. Puseij. 
Sir, — Having had three years' experience of growing peas in tlie 
place of maiiing a summerland, and afterwards drilling turnips 
between the rows, I take the liberty of sending you an acco\mt of 
it for insertion in the Royal Agricultural Society's Journal, if you 
think the information worth communicating. 
I adopted the practice from a highly cultivated and well-kept 
farm in my neighbourhood, in the occupation of George Hooper, 
Esq., of Cottington, \\hose system for many years past has been 
to make a summerland only for swede turnips, contracting with a 
London seedsman to grow white peas, which he has sown on the 
portion of his ground intended for common turnips; I had ob- 
served the excellent turnips he almost invariably grew after peas, 
better indeed than I, before artificial manure was introduced, 
could obtain after preparing a summerland. His practice (which 
I at first followed, but had not after the first year the same faci- 
lities and command of manure for coniinuing) is to carry out 
from a mix-hill made on purpose, about two-thirds of a full coat 
of manure before ploughing his wheat stubble for peas, but my 
greater difficulty of procuring this extra quantity of dung, at a 
time when all the spare dung from the yards was required for 
beans, taught me to succeed as well, and I think at less cost and 
trouble, with artificial manure. 
Oa my first trial in 1844, not being able to make a contract 
with a seedsman, I obtained, as well as I could, the proper kind 
iVom Mark Lane, and had tViree sorts of white peas sent down to 
me ; all three that year produced well, averaging respectively 
3 quarters 6 bushels, 4 quarters 3 bushels, and nearly 5 quarters 
per acre. Part of the ground on which the first lot grew was 
manured from a mix-hill, and there the turnips after them were 
moderate only, the pea-straw covering the young plant too strongly 
and thickly ; but in another field of the same quality of land, con- 
taining rather less than 8 acres, which had been treated with 
3 cwt. of Peruvian guano in the spring, and afterwards with some 
manure rotted to mould and mixed with turf-ashes drilled in with 
the turnip-seed, I had a most excellent crop of green -rounds, 
which kept 16 score of tegs two months all but 5 days. The 
4 qrs. 3 bush, peas were too late a sort, and had too much bine, 
leaving me plenty of plant, but the turnips did not bulb well. 
Where I grew nearly 5 qrs. per acre, I had sown 2^ cwt. of 
guano only, and had a very fair piece of white rotuul turnips. 
In 1845 I grew 10^ acres of early franii^s for Messrs. Ratt
