Rural Architecture —Sub- Soil Plows.

not an odious tyranny dragged Bunyan away 
from this ancient spot, instead of writing a 
u Pilgrim’s Progress,” ne would have given 
us a work almost as immortal on Husbandry ; 
for how often rural subjects and images 
abound in this singular production. We 
hear talk of flocks and herds, gardens and 
flowers, fields of wheat and corn, ground 
well sowed and tilled, muck and manure 5 
and as we wander on we are carried over 
By-path meadow, cross the valley of Humili¬ 
ation, wade through the slough of Despond, 
rest in an arbor on the hill of Difficulty, and 
after the still more fatiguing ascent of the 
Delectable Mountains, are regaled in orch¬ 
ards and vineyards, and sip at the coolest 
and most delightful of fountains. Yes, we 
repeat, if John Bunyan had not been a 
preacher and author, he certainly must have 
become a farmer.

SUB-SOIL PLOWS. 
BARNABY AND MOOER’s SIDE-HILL PLOWS. 
When we were in England we devoted 
some time to the examination of sub-soil 
plows, but all we saw there we thought en¬ 
tirely too expensive, and so heavy that it re¬ 
quired from three to four pair of strong 
horses to move them. This we knew would 
never answer with American farmers, and 
since our return we have suggested several 
models to our mechanics, but have never 
been able to get anything promising to com¬ 
bine cheapness, strength, and good work so 
effectually, as the sketch which Mr. Cornell 
was so obliging as to make for us one day as 
he called at our office, on his way south from 
Ithica. 
As to Barnaby and Mooer’s side-hill plows, 
we agree with Mr. Cornell in saying that it 
is the very best known for this purpose, and 
we have seen it do excellent work on level 
land. We are of opinion that it will answer 
an admirable purpose in the washy lands of 
the south, especially in what they call “ hori¬ 
zontal ” plowing, and we have sent several out 
to our friends there for trial, and if they 
prove successful, we have no doubt that they 
will soon be more generally used in that 
quarter than any other. But before intro¬ 
ducing Mr. Cornell’s letter, we give the en¬ 
graving of one of the best kinds of English 
sub-soil plows that we know of. We copy 
it from the London New Farmers’ Journal, 
of December, and believe it is a recent in¬ 
vention. Its construction is so easily made 
out from the engraving, that we give no ex¬ 
planation of its different parts. In some soils 
we should think this plow would work well. 
For the American Agriculturist. 
New York, Feb., 1843. 
Messrs. A. B. & R. L. Allen : 
Having become satisfied of the utility of sub-soil 
plowing, and equally well satisfied that the heavy, un¬ 
gainly English plow, hitherto introduced into this 
country, is not well adapted for the purposes ol 
the American farmers, I herewith give you a rough 
sketch of a sub-soil plow, that I think will perform the 
office of loosening the sub-soil in a better manner than
