The Committee on Patents and the Patent Office, to whom was referred the application for the extension of the patent for a planing machine granted to Uri Emmons, report:

That the original patent was granted on the 25th of April, 1829. A patent for a planing machine of a similar character had been previously granted to William Woodworth on the 27th December, 1828. A controversy arising between the parties, it was adjusted by an agreement, by which the territory of the United States was divided between them. The machine known as Woodworth's combined all the essentially important characteristics of both patents.

Woodworth's patent was extended for seven years, under the act of 1836. Emmons failed to procure an extension, though there would seem to have been no good reason for refusing such extension. In 1845, the administrator of Woodworth procured another extension for seven years, by act of Congress. Emmons, however, had no benefit from the extension of Woodworth's patent.

What is known as Woodworth's machine, embracing all the valuable principles of both inventions, has been protected for nearly twenty-eight years, and will become public property on the 27th of December, 1856.

The Committee of the Senate on Patents and the Patent Office for the last Congress, being of the opinion that as Emmons was, at least, equally deserving with Woodworth, reported a bill granting him an extension to December 27, 1856, the day when Woodworth's last extension will expire. That bill did not pass, and it is manifest that such a extension now would be of no service to the petitioners. They ask an extension for seven years from that period.

Your committee are of opinion that the prayer of the petitioners ought not to be granted. The machine will, at that time, have enjoyed protection for twenty-eight years. And however it may be regretted that Emmons may have failed to receive a proper share of the benefit, it will be unjust longer to withhold his invention from the public. Such an extension as that applied for would impose great burdens on the community, and your committee see no sufficient grounds for imposing them for the benefit of the petitioners. They therefore report adversely.

Mr. FESSENDEN made the following

REPORT.

[To accompany Bill S. 396.]

The Committee on Patents and the Patent Office, to whom was referred the petition of Nathan Scholfield for the renewal of a patent granted to him on the 17th of May, 1836, report:

That, on said 17th of May, 1836, said Nathan Scholfield obtained a patent for an important improvement in a machine to regulate the motion of water wheels; and at the expiration of his original term of fourteen years, on proof that he had obtained no adequate remuneration, he obtained an extension, which will expire on the 17th day of May, 1857. He prays for a further extension of seven years from and after that day, on the ground that he has not been sufficiently remunerated for his invention.

Your committee are satisfied that his improvement is a valuable one, and that he is but just beginning to realize a reward for his labor and skill-owing, probably, to the nature of his improvements, which required time to perfect, and render them efficient, and not to any fault on his part. Believing that the public will not be injured by granting him a further extension, your committee therefore recommend the passage of a bill granting to Mr. Scholfield a further extension for seven years from and after the 17th day of May, 1857, which bill is werewith submitted.

Mr. FOSTER made the following

REPORT.

[To accompany Bill H. R. 226.]

The Committee on Private Land Claims, to which was referred House Bill No. 226, "An act to authorize the legal representatives of Pascal L. Cerré to enter certain lands in the State of Missouri," have had the same under consideration, and submit the following report:

The committee attach hereto, and make a part of this report, the report from the House Committee on Private Land Claims, submitted by Mr. Porter, on the 3d day of April, 1856, which is as follows:

That it appears from the evidence submitted to your committee with the petition, together with that procured by your committee from the General Land Office, that the proper Spanish authorities of Louisiana, in due form, made a concession to said Pascal Leon Cerré of 7,056 arpens of land, on the 9th of November, 1799, to be located in the then Territory of Louisiana, now State of Missouri. That the recorder of land titles of Missouri, and the two commissioners associated with him under the provisions of the act of Congress "for the final adjustment of land claims in Missouri," approved July 9, 1832 -the recorder and commissioners constituting a board of commissioners, as required by said act-reported in favor of said claim, and the same was confirmed to the claimants by the act of Congress of July 4, 1836, entitled "An act for confirming claims to lands in the State of Missouri, and for other purposes." It further appears by the evidence before your committee, that said claim of Pascal Leon Cerré for 7,056 arpens was entered as number two in the first class of the decisions of said "board of commissioners," (see document No. 59, House of Representatives, first session, twenty-fourth Congress, pages 29, 30, and 31,) to be surveyed in two parts or halves, the first one at the "Big Spring" of the river Maramec, and the second half at the fall of the forks of Gasconade and those of the Maramec called "the Muddy." For the act of confirmation of said claim, see United States Statutes at Large, volume 5, page 126, chapter 361.

The first part of the claim has been described as survey No. 3,120 for 3,001.25 acres, equal to 3,528 arpens, situate in townships 37 and 38 north, of range 6 west, of township 38 north, of range 5 west;
