14th. That the sun will rise tomorrow is a moral certainty, but the existence of this newly discovered principle in vegetation, can be demonstrated to a philosophical and mathematical certainty, as the discovery is founded on self-evident facts; a knowledge of which, from its nature and importance, should be one of the first lessons to be taught to a young agriculturist, in a state agricultural school or elsewhere; to the young lady who would rear her house plants successfully, as well as to all gardeners, and also worthy of the attention of all who value improvement in art and science, and in the con* dition of our species, man.

15th. That in the cultivation of all agricultural crops, a knowledge of the principle is essential, to know how to preserve the vitality and healthy growth of the plants.

16th. That the discoverer's system of cultivation is formed by a combination of discoveries.

17th. That he has discovered the cause of the excessive potato rot, and an economical and natural method of preventing it, almost to a moral certainty.

18th. That the bonus or reward of $150,-000, which is suggested in said Assembly Document, No. 23, by eighty of the principal tax pavers of the town of the discoverer's nativity and residence, and others of Dutchess county, when paid by the state, will be a powerful stimulus to cause all ter-ra-culturisU to test the existence of this discovered principle in nature experimentally; a practical knowledge of which will cause them to abandon their traditional mode of cultivation, and to adopt the improved system, which is in direct opposition to their traditional custom, and therefore may require (to be quickly introduced,) the most powerful stimulants, conviction, interest and popularity, to make the inroad on their custom.

19th. That the honor of the Republic demands legislative action on the subject without delay, even should the discoverer demand of the state the amount which he had encouragement to believe congress would appropriate eleven years since, say three quarters of a million, instead of this state's proportion of that amount, but he has never set any price.

20th That the want of lobby-money, to cause honorable members of the legislative bodies to read all the proofs, may have been the principal reason for the inactivity of Congress and the state legislature.

19th. That on the 22d ult. Hon. Dr. Peter Crispell, Jr., of Ulster county, who was chairman of New York Assembly Committee on Agriculture, in 1849, stated to the discoverer, and Mr. Rutzer of the Pough-keepsie Hotel, and others, that this year, an unfavorable year for Maize, for the first time, he had grown more than 100 bushels of shelled Indian corn to the acre. When the discoverer explained the principle of his botanical discovery to the chairman, in Jan. 1849, Mr. Crispell told the discoverer that he thought the information worth------dollars to him, although he had no right to use it. And on the 22d ult. he pronounced the preceding description of the discoveries "very good."

Hon. Judge 0. Titus, of Dutchess county, used the same expression after perusing it a day or two before, confirming with pleasure the letters that he had written on this subject, to members of Congress and the state legislature.

That during the present year the discoverer has applied his system of cultivation to the growing of the sweet potato in Dutchess county, N. Y., and, as in all other cases, where he has applied it to any species of plant for the first time, his success has far exceeded his expectations, growing them in good garden sou. - without artificial beat, manure or sand - in 95 days after the 21st of June, more than eight inches in circumference.

The discoverer will add, that each and every individual to whom he has ever explained "a confidential knowledge of this law in nature, has admitted that to the extent of their ability to judge, the undersigned is the orfgnal discoverer.

Said bill No. 395, for testing the practicability, utility and value of the improvements and discoveries, passed the Assembly only two days previous to the adjournment of the last legislature, the Senate laying it on their table; a portion of that honorable body assigning as a reason., that as the bill anticipated a conditional appropriation for defraying the discoverer's .travelling expenses, no member of the legislature could be constitutionally one of the testing committee; a member of the Assembly being on the committee as the bill passed the Assembly.

Hon. A. J. Downing was in Europe during the past season of vegetation, and Hon.

E. P. Prentice of Albany county, President of the State Agricultural Society, and one of its principal founders was substituted. And alter the adjournment of the legislature the committee agreed to examine the subject; for which purpose the discoverer called on the committee in April, May and June, and again, to learn their conclusion, on the 8th and 9th inst., when the committee stated that they considered the existence of this newly discovered law in the vegetable kingdom, "self-evident," when exhibited and understood; and that as far as either of them could judge, the undersigned was the first discoverer of it; and that neither of them had been able to detect the discoverer in error in any of his various positions relative to his discoveries and system, nor in anything that he had said on the subject.

The committee, on the 8th inst., agreed to present the subject to the New York Stale Agricultural Society on the 15th of January, (its annual meeting,) and solicit the society to apply to the legislature to cause the discovery, or discoveries and system to become public property.

Yesterday Judge - - of Dutchess county, said, "that there was one thing about this subject that he could not understand, and that was, that the discoverer apparently could get the recommendation of every person to whom be imparted a confidential knowledge of his discovery and system, commending to the public, either the principle or the practice, or both; and as yet, no efficient legislative action on the subject; to him, he said, it was incomprehensible; that he could not comprehend it."

But the people must now "come to his rescue," or the discoverer must abandon it again, as he did ten years ago.

As civilised society, has no law to protect such discoveries, the discoverer asks of each citizen who is not incredulous, some direct or indirect aid, for the benefit of the human race, and for the honor of the age in which we live. Russell Com stock. Mabbetts-vill, Dutchess Co., N. Y., Decr 12, 1850.

P. S. The reader who takes an interest in this subject, (and who does not?) will please attract the attention, (per mail or otherwise) of some member of the legislature to it, ana also show it to members of the State Agricultural Society. R. C." Poughkeepsie American, Jan. 11,1851.
