much wool^ and several times the amount of tallow. But as 
an equal weight of mangel wurtzel or turnips can be raised 
at an expense of about -^q of what is required for the produc- 
tion of most kinds of grain, the superior economy, except 
for fattening, will at once be perceived. If this table be cor- 
rect, the Lincolnshire plan of using barley instead of so 
much oil cake, is more economical. The present cost of 
1000 lb. of oil cake is 98s., and that of barley 78s., but the 
feeding quality of barley is 136 + 60 = 196, (while that of 
rape cake is 116 -[- 26 = 142,) or about I greater. A new 
species of barley from Peru, a small quantity of which is 
growing in Lord Hawke's garden, at Womersley, and some in 
Lord Lascelles' a£id Sir J. Johnstone's, is likely to become 
very valuable for sheep feeding ; the quantity yielded is equal 
to from 3000 to 4000 times the quantity sown ; the produce 
per acre 12 quarters. It is the Hordeum gymno-hexas- 
tichum of Lowe, and probably that cultivated in some parts 
of Germany ; and on account of its productiveness termed 
by the French orge celeste. Lowe says that it is greatly 
esteemed, and deserves more attention than it has yet re- 
ceived: it is even now (1st Aug.) tillering fresh ears. 
The Wheat grown on the Wolds does not produce so 
heavy and large a crop as on stronger soils, but the grain is 
even and fine. Three quarters per acre are reckoned a satis- 
factory return. It is said to be heavier after rape than 
any other crop. Finlay son's harrow is used in some places 
on the cloverleys, and the couch grass cleared and burnt : by 
this mode a cleaner fallow for the turnips, which succeed the 
wheat, is said to be made. In others a presser follows the 
ploughs, with a drill box attached. Wheat on the deep wold 
lands, is particularly subject to mildew^ called there niglit 
ripening but there is no doubt that this disease is owing to 
the attacks of minute fungi, with the natural history of which 
we are well acquainted. There are about five parasitic fungi
