On the Drill Husbandry of Trmups. 
V. — T/te Manner of performing tJie Hoeing. 
In considering: how turnips ought to be hoed, it is necessary to 
bear in mind the followinof three points: — 
1st. At what distance from each other in Ihc rows, under their 
circumstances as to manure, Sic, turnips in rows any given dis- 
tance asunder would attain the largest size per turnip ? 
2nd. How far a greater number of turnips in the rows may 
make up for their being of smaller size ? 
Turnips, considered as spheres or balls, are in proportion to 
each other as the cubes of their diameters. 
That this point may be more generally understood, I will show 
in figures the comparative solid contents of nine turnips, whose 
diameters are, 4, 5, 6, 7, 8, 9, 10, II, and 12, respectively: —

Where the diameter is doubled, the solid contents of the turnip 
are increased eightfold — 512, the cube of 8, being equal to 8 
times 64, which is the cube of 4 ; and 268, the contents of the 
turnip, being also 8 times 33g. Where the diameter is trebled, 
the size of the turnip is increased 27 fold, — 1728, the cube of 12, 
being equal to 27 times 64, which is the cube of 4. Thus a 
turnip which is 8 inches across, is equal in bulk to eight turnips 
which are only 4 inches across, and a turnip 12 inches across is 
equal in bulk to ttventy-seven turnips which are 4 inches across. 
3rd. At what size turnips afford the greatest nutriment to the 
animals which consume them in proportion to their bulk ? 
their attention to G. in my schedule. Tliis e;entleman lives between Biigg 
and Bai'ton-on-IIumber ; he is acknowledged to be one of the best farmers, 
if not the best, in the county of Lincoln, and his name may readily be 
known to any one travelling that way who will inquire for him by my de- 
scription. In his letter to me of February 21, 1842, accompanying that 
return, he says, " 1 have tilled up your schedule according to the cus- 
tomary mode of turnip husbandry practised l)y me and most agriculturists 
in lliis neiglibourtiood. 1 dare say you will be surprised at my remark 
respecting drilling so near as 14 inches; but I am of opinion that, where 
the same quantity of manure is applied, as great a weight per acre may be 
produced, and they will be uuich belter food for sheep. Still the distance 
13 objectionable on account of not being able to use the horse-hoe.''
