Groioth of Mangold. 443 
for wlicat on those plots where mangold was grown with Peruvian 
gnaiio, there had been no straw manure for probably foui* or five years. 
Mr. Lawes has expressed an opinion, that mangold, to be grown suc- 
cessfully, must either have farmyard manm-e applied to the crop 
before it is sown, or at all events to the previous crop. It will also 
be desirable to look forward as well as backward. Where the farm- 
yard manure was applied last year, the leaves are ploughed in ; and I 
shall reckon on gi-owing barley this year ivithout fiu'ther dressing. 
Where Lawson's guano and the Peruvian guano were applied last 
year, there I shall deem it desii-able to add a fiu-ther dressing of 
2 cwts. of guano for this year's barley. My proximate estimate for 
the barley crop is, on the adjacent land where I grew swedes, 
46 bushels of barley per acre ; after a double dressing of Peruvian 
guano 40 bushels, but of a somewhat inferior quality. Where the 
farmyard maniu'e was applied last year, and no fui-ther manure is 
added this year, I expect to grow 36 bushels, but of a superior quality 
to that which follows Peruvian guano. If on the plots maniu'od with 
Lawson's and Peruvian guano for mangold, barley had been di'illed 
this year, mthout any further dressing, I shovdd only expect to reap 
about 30 bushels. And after all we should rather anticipate that the 
layer will be quite as good where the farmyard manm-e was applied 
three years ago, without further di'essing, as where a double dressing 
of guano had been applied. If then you give a dressing of guano 
directly to the mangold, and then afterwards to the barley, the cost 
will be nearly identical with the single application of farmyard 
manure ; for the first dressing of guano will cost 50s., and the next 
about one-half of that, or 25s. ; whilst I estimate a single dressing, 
amounting to 10 tons of farmyai-d manure, at only 80s., or a crown 
more. 
One word on the preparation of land for mangold. Prompted in 
great measui'e by Mr. Pusey's teaching, at one time we used to be 
anxious to get some stolen crops in directly after harvest ; but cold 
springs and dry summers prevented those crops being of such use to 
ns in the Eastern Counties as they are in the Southern and Western 
districts. Now our first object after harvest is to prepare the land 
for mangold. This field was first ploughed, twice dragged, and then 
worked with three horses in a haiTow in the month of September, 
After wheat-sowing in November, it was all ridged up ; then the 
plough was worked between the ridges as deep as thi-ee horses could 
draw it, and the field left imtil spring. In the spring the ridges were 
only just picked over to take the weeds out. The manm-e was then 
put in, and it only required to be split. A like com-se was adopted 
in 1861, and its importance exhibited in the wet spring of 1862. 
The Chairman, Sir Edward Kereison, laid before the meeting two 
sets of experiments made by Mr. Horn, his bailiff, on his own farm, 
and remarked that beetroot is now being much more largely grown 
than formerly, particularly in the Eastern Counties, where a con- 
siderable breadth of swedes has been discontinued in its fiivour ; the 
dryness of the summer season there having led to the crop of swedes 
being constantly destroyed by the fly : —
