Trial of American Plows. 139 
With these facts before them, the public will' now see how 
great an injustice it would be for congress to extend the patent of 
Jethro Wood, and give his heirs, or rather a company of greedy 
speculators, the privilege for seven years, of exacting 50 cents 
per plow from every one engaged in their manufacture. 
I hope these facts will be widely disseminated by the press 
throughout the United States; for the hard working farmers and 
planters ought to be immediately apprized of what so vitally con- 
cerns them. As the bill is still pending before the House of 
Representatives, let all those opposed to injustice and special privi- 
leges take pains to call the attention of every member to the subject 
so that the iniquitious measure may be defeated. — Rochester De- 
mocrat. A. B. Allen. 
COMPARATIVE TRIAL OF AMERICAN PLOWS IN ENGLAND. 
In a late No. of the Mark Lane Express, we find thejfollowing: 
" After maturely trying Mr. Slocum's plow against the best of 
ours their performances were as follows: — First, his plows tried 
against Adam's Northampton plow and Howard's Champion plow, 
on a clay soil, not very strong clay. Howard's plow at five inch- 
es deep by eleven wide, draught 31 stone: Adam's plow at the 
same width and depth, thirty stone; whilst the American at five 
inches by fourteen inches wide, drew only twent}'-six stone. In 
justice to the American plows, I must say that they cut and turned 
their furrow quite as well as the others, at the same time break- 
ing the land to pieces, making a capital preparation for either 
drilling or dibbling; indeed they are the most simple, light, strong, 
and efficient plows that it is possible to conceive. Yesterday^ a 
gentleman farmer and myself put one of them on trial with one of 
Comtam and Hallet's dynamometers against the lightest drawing 
plow of my own upon a field, one of which is a very strong clay, 
and the other a clayey lea mold, which very few plows will 
clear themselves in; the middle a mixture of the two, with a lit- 
tle gravel in it. W^e first tried them at five inches deep, my 
own at 1 1 inches wide, which was as much as it would cut up and 
turn properly, in the strong clay, and it drew 44 stone; in the 
mixture, 48 stone; and in the lea mold 46 stone. We then tri- 
ed it at 8 inches in depth by 11 in width, when we found on the 
strong clay 46 stone; on the mixture 44 stone, and in the lea 
mold forty-eight stone. We then tried the American plow at 5 
inches deep and fourteen wide, and found the draught — in the 
strong clay, 38 stone; mixture 40 stone; in the lea mold, 32 
stone; the same width, and 8 inches deep in the clay, 42 stone; in 
the mixture 43 stone; and in the lea mold 36 stone. * * 
Mr. Slocum's implements are the strongest, lightest, and the 
jnost perfect articles that ever came under my notice. — Peter Love.
