. The discordance in practice, as well as in opinion, 
prevailing on this question, induced some scientific 
men to-institute a series of experiments, having for 
object a full and regular solution of it. With this 
view, parcels of dung (long and. short) were taken 
from the same stables, on the same day, and applied 
to crops of the same kind, growing on the same 
fields. The result was perfectly conformed to theo- 
ry, and similar in all the experiments: Those parts 
of the field, to. which the short dung was applied, 
gave. the best crops the first year, but those on which 
the long dung had been laid, gave the best crops 
the second and third years ; a fact, which authorizes 
the conclusion, that if we wish to obtain one great 
crop, the rotted dung is best; but when we look to 
more permanent imprnvemant the long qanga is to 
be preferred. ft 
2d. Which is the better practice, to spread:r ma- 
nure on the surface, or lay it many under the 
ground? 
In favor of the former practice, it has been con- 
dinded, that the distribution of the dung could 
more equally be made on the surface, with a spade, 
than under ground, with a plough;(1) and for the 
latter, that all tap rooted plants, entering far into 
the earth, required it to be laid deep, and that those 
of fibrous roots, would be sufficiently benefitted by 
its exhalations. Both modes, however, are obvi- 
Oran ; 
(1) ‘Fhe English (are said) to have a machine attached to the drill, that goes before 
and distributes the manure at the necessary depth. In planting potatoes, we make a 
bed of dung forthe plant. Why not epply the same reasoning and the same practite 
to all seeding of the ground ? :
