Our remarks on the special qualities of the seve¬ 
ral plows have been given with so much detail un¬ 
der the trials on “ old land” and on “ stiff sod,” 
that we deem it unnecessary to say more in relation 
to them in the present connexion, except the gene¬ 
ral remark, that the greatest deficiency noticed in 
most of the plows which were submitted for this 
trial, was one which would have entitled them to 
commendation in stiff and tenacious soils, and that 
is, they lapped the furrows too much, which in¬ 
creased the friability of a soil already too loose. 
They were also deficient in burying the grass. In 
most of the lands it could be seen protruding 
through the interstices, and a shower having occur¬ 
red soon after the trials were finished, it grew in a 
few days so as to cover the field with a very unde¬ 
sirable verdure. These defects, however, were 
admirably obviated by the plows to which the pre¬ 
miums are awarded. All the plows were gauged 
to work six inches by twelve. 
Trial of Side-Hill Plows. —These plows were 
tried on a steep, side hill in the same field where the 
trials on “old land” were made. There were three 
plows entered for the premium, viz: 
Bosworth, Rich & Co.’s, price $7.00, wt. 123 lbs. 
Prouty & Mears’,........ 9.00, 11 110 lbs. 
Eddy & Co.’s,... 9.00, “ 111 lbs. 
They all performed well, and are well worthy of 
their makers’ reputations, and of the confidence of 
the public ; but all things considered they esteem the 
plow of Bosworth, Rich & Co. the best. It is truly 
an excellent implement, and they recommend it with 
great confidence to those requiring such an imple¬ 
ment, as one which will give them entire satisfaction. 
Trial of Sub-soil Plows. —Three plows were 
entered for this trial, viz: 
Prouty & Mears’ B Sub-soil Plow. —Price $10, 
weight 103 lbs., draft 750; in a very stiff hard-pan, 
filled with stones; sub-soil depth 1U inches. The 
draft of this plow in a similar soil, but much more 
free from stones, was 650 lbs. 
Prouty & Mears’ C Sub-soil Plow, price $8, 
weight 89| lbs., draft 650 lbs.; in a sub-soil similar 
to that in which B was tried, less stony than the 
first trial, but much more so than the second one; 
depth 10| inches. 
Bosworth, Rich & Co.’s Sub-soil Plow, price 
$7, draft 650 lbs.; in a sub-soil similar in texture 
and stones to that in the second trial of Prouty & 
Mears’ B plow, depth 101 inches, weight 88| lbs. 
On a second trial, its draft was 700 lbs., with a 
depth of 10£ inches. The adjustment attached to 
Prouty & Mears’ C plow, by which the amount of 
pulverization may be increased or diminished, ac¬ 
cording to circumstances, gives it a preference over 
others, and entitles it to a premium. It is proper, 
however, to add, that the plow exhibited by Bos- 
worth, Rich & Co. was an excellent implement, 
and will, in most respects, give good satisfaction to 
purchasers. 
Measurments of various Plows. —Notwith¬ 
standing the acknowledged importance of the plow 
as bearing on the quantity, quality and cheapness of 
vegetable, and, to a considerable extent, of animal 
food, little is yet known with respect to its theory. 
One obstacle to its investigation has hitherto been 
the want of reliable data. As one contribution to 
the removal of this obstacle, we subjoin the follow¬ 
ing measurements of various plows which have been 
exhibited at the trials: 
Michigan Sod and Sub-soil Plow. —We have 
refrained in the remarks hitherto offered from mak¬ 
ing any comments on the plow offered by Messrs. 
French & Smith, and called by them the Michigan
