590 Oil the Double Culture of Turnips between Peas. 
and Rulley, and 10 acres for the late Mr, Bristow ; also 12 acres 
of the double-blossom frames (if such is their proper name), 
which had the year before produced nearly 5 qrs. per acre. 
Bait's and Bristovv's were both mamu-ed with 3 cwt. guano in the 
spring, and farm-yard manure rotted to mould and screened with 
ashes as before, when the turnips were drilled ; the ungenial sum- 
mer produced but 2 qrs. to the former lot per acre, and 2 qrs. 
2 bush, to the latter, but most excellent green and white turnips 
on both. The 12-acre piece, which had no guano, but received 
the mould and ashes, produced 2 qrs. 3 bush, per acre of peas, 
and the turnips not so good. 
This year, as well as the last, I allowed the mould and ashes 
to miss at certain places, where the guano had been broad-casted 
before the peas, but could observe no difference in the size of the 
turnips ; but where guano was purposely omitted on Mr. Bristow's 
lot, and on the r2-acre piece, it was discernible both in the colour 
of the peas and size of the turnips. 
The season of 1846 has been memorable for the dolphin 
among the pea-crop, and a dry hot seedtime for tui nips. I have 
grown principally the double-blossomed frames, and some of Mr. 
Bristow's early frames. I have used both guano, and bones dis- 
solved in sulphiu'ic acid, manuring for the turnip only; the guano 
turnips have, I think, turned out best, but the season has not been 
a favourable or fair one for making equal experiments. 
I will now proceed to detail the method of growing and ma- 
naging the double crop, which from the foregoing experience I 
consider the best and most economical. As a system it can only 
be carried out where the farm is kept habitually very clean, and 
all cuich-grass, if not scarified in the wheat-gratten after harvest, 
rarefully forked out, as well as in the clover leys ; and the horse 
and hand hoeing, and thistling well executed as soon as requirefl. 
Tile portion of the farm intended for common tm'nips (swedes I 
have never attempted as a double crop) being ploughed as usual 
in the winter a good depth, h niggetted or stirred as much before 
the l.st of April, or after the pressure of barley season, as possible, 
and 3 cwt. of good Peruvian guano, mixed with an equal quantity 
of light mould, sown broadcast in the track made by the tines of 
the niggett, being covered in inmiediately by the liarrow which 
precedes the pea-drill; four bushels of early frames are deposited 
in rows of 12 to the rod wide, and as soon as high enough are 
liand-hoed at 3s. 6d. per acre, then horse-hoed, then quickly hand- 
hoed again, and at the last slightly earthed as the horse-hoe 
follows, by means of a band tied above the plate, the final horse- 
hoeing being timed just before the peas meet together, Tlie 
tin-nip-drill should now follow immediately, and if convenient for 
drilling 12 furrows to the rod, will take 3 or more furrows at a
