To place Philip P. Barbour, of Virginia, in the Speaker's chair, and to prevent the reelection of John W. Taylor, of New York, the tried friend of the administration, became the next object of all those who hoped to rise by opposing it. The partisans of Barbour were successful, and the consequences of his elevation were immediately apparent. As the Committee of Foreign Relations was, by a practical rule, the medium of communication between Congress and the executive government, it was customary for the Speaker to constitute it chiefly of members who coïncided in their views. But many of those now appointed by Barbour, especially the chairman, were hostile to their politics. To this committee all the delicate and critical papers relative to the foreign relations of the United States were to be confidentially communicated. No arrangement could have been more annoying to Mr. Monroe and his cabinet, or more symptomatic of a settled opposition.
By a vote passed in March, 1817, the Senate had required of Mr. Adams a report on weights and measures; and in December, 1819, the House of Representatives had by a resolution made the same requisition. To this subject he had directed his attention when in Russia; and had devoted the leisure his duties as Secretary of State permitted, without approximating to its completion, owing to the number and perplexity of details its pursuit involved.
In the summer of 1820 he relinquished a visit to his father and friends in Massachusetts, and concentrated his attention, during six months, exclusively on this report, which he finished and made to Congress, in February, 1821. At the conclusion of his work he thus expresses himself: "This subject has occupied, for the last sixty years, many of the ablest men in Europe, and to it all the powers, and all the philosophical and mathematical learning and ingenuity, of France and Great Britain, have been incessantly directed. It was a fearful and oppressive task. It has been executed, and it will be for the public judgment to pass upon it."
From the abstruse character of this work, the labor, research, and talent, it evidences have never been generally and justly appreciated. It commences with the wants of individuals antecedent to the existence of communities, and deduces from man's physical organization, and from the exigences of domestic society, the origin of measures of surface, distance, and capacity; and that of weight, from the difference between the specific gravity of substances and its importance in the exchange of traffic consequent on the multiplication of human wants, with the increase of the social relations. He then proceeds to state and analyze the powers and duties of legislators on the subject, with their respective limitations. The results of his researches relative to the weights and measures of the Egyptians, Hebrews, Greeks, and Romans, are successively stated. From the institutions of the nations of antiquity he derives those of modern Europe and of the United States. He praises the "stupendous and untiring perseverance of England and France" in this field, and explains the causes which have not rendered their success adequate to their endeavors. The system of modern France on this subject he investigates and applauds, as "one of those attempts to improve the condition of human kind, which, although it may ultimately fail, deserves admiration, as approaching more nearly than any other to the ideal perfection of uniformity in weights and measures." After stating the difficulties which prevented other nations from seconding the endeavors of France, Mr. Adams concludes this elaborate treatise with the opinion that universal uniformity on the subject can only be effected by a general convention, to which all the nations of the world should be parties. Until such a general course of measures be adopted, he regards it as inexpedient for the United States to make any change in their present system. After an elaborate enumeration of the regulations of the several states of the Union, accompanied by voluminous documents, he concludes with proposing, "first, to fix the standard with the partial uniformity of which it is susceptible for the present, excluding all innovation. Second, to consult with foreign nations for the future and ultimate establishment of permanent and universal uniformity."
The Senate ordered six hundred copies of this report to be printed. But its final suggestions were not made the subject of action in either branch. A writer of the day said, with equal truth and severity, "It was not noticed in Congress, where ability was wanting, or labor refused, to understand it." As Mr. Adams was one of the candidates in the approaching presidential election, party spirit was inclined to treat with silence and neglect labors which it realized could not fail to command admiration and approval. In England the merits of this report were more justly appreciated. In 1834, Col. Pasley, royal engineer, in a learned work on measures and money, acknowledged the benefits he had derived from "an official report upon weights and measures, published in 1821, by a distinguished American statesman, John Quincy Adams. This author," he adds, "has thrown more light into the history of our old English weights and measures than all former writers on the subject; and his views of historical facts, even when occasionally in opposition to the reports of our own parliamentary committees, appear to me most correct. For my own part, I do not think I could have seen my way into the history of English weights and measures in the feudal ages without his guidance."
In the summer of 1821 Mr. Adams was apprized that rumors, very unfavorable to his reputation, even for integrity, had been industriously circulated in the Western country. It had been stated that he had made a proposition at Ghent to grant to the British the right to navigate the Mississippi, in return for the Newfoundland fisheries, and that it was in that section represented as a high misdemeanor. Mr. Adams said, that a proposition to confirm both those rights as they had stood before the war, and as stipulated by the treaty of 1783, had been offered to the British commissioners, not by him, but by the whole American mission, every one of whom had subscribed to it. The proposition was not made by him, but by Mr. Gallatin, who knew it would be nothing to the British but a mere naked right, of which they could not make any use. It was accordingly promptly rejected by the British commissioners, and made the ground of a counter proposition of renouncing the right they had, under the treaty of 1783, of navigating that river, on condition of our renouncing the old article on the fisheries. Mr. Adams at once declared that, if it was acceded to, he would never sign the treaty; and it was promptly rejected by the American commissioners. When he was again told that he would be accused in the Western States of the proposition to confirm the British rights as they stood before the war, he replied, that he had no doubt it would be so; for Mr. Clay had already, in one of his speeches in Congress, represented that this proposition had been made by a majority of the Ghent commissioners, he being in the minority, without acknowledging that he had himself signed the note by which the offer was made, and without disclosing how lightly the concession was estimated by the British commissioners, and how promptly they rejected it.
Accordingly, on the 18th of April, 1822, John Floyd, of Virginia, who, both in that state and in Congress, was active in seeking and scattering malign imputations concerning the political course of Mr. Adams, called, in the House of Representatives, for a letter, written by Jonathan Russell, in 1814, to Mr. Monroe, then Secretary of State, and, as he stated, deposited in that office.
This call of Floyd was the springing of the mine for a long-meditated explosion. On searching the records of state, no such letter could be found. Mr. Russell immediately volunteered a copy, and deposited it in that office. This letter was addressed to James Monroe, then Secretary of State, and was dated Paris, 11th of February, 1815. It was a letter of seven folio sheets of paper, and amounted, said Mr. Adams, to little less than a denunciation of a majority of the Ghent commissioners for proposing the article recognizing the fishery, and the British right to navigate the Mississippi,—a proposition in which Mr. Russell had concurred. He wrote this letter at Paris, where all the commissioners then were, without ever communicating it to Mr. Adams, or letting him know he had any intention of writing such a letter. It was a most elaborate, disingenuous, and sophistical argument against principles in which Mr. Russell himself concurred, and against the joint letters of the 14th December, 1814, to which he signed his name. His motives, Mr. Adams considered, for writing then to a Virginian Secretary of State, under a Virginian President, were, apparently, at once to recommend himself to their sectional prejudices about the Mississippi, and to injure him in their esteem and favor, for future effect; and that his motive for now abetting Floyd, in his call for these papers as a public document, was to diminish the popularity of Mr. Adams in the Western States.
With these views of the purposes of Floyd and Russell, Mr. Adams immediately endeavored to obtain the original letter, of which Mr. Russell had now deposited in the Secretary of State's office a paper purporting to be a copy. The original he ascertained was still in the possession of Mr. Monroe, who had received it soon after its date; but, as it was marked "private" by Mr. Russell, he considered it confidential, and did not place it in the office of the Secretary of State. On ascertaining these facts, Mr. Adams claimed the original letter from Mr. Monroe, believing, from internal evidence, that the duplicate, instead of being a true copy of the original, had been in some respects adapted to present effect. Mr. Monroe declined to listen to the repeated remonstrances of Mr. Adams, and continued to maintain that he could not, with honor, make the original letter public. He did not consent until he was called upon for it by a vote of the House of Representatives, proposed by the friends of Mr. Adams, and resisted by Floyd and his party. The original letter being thus obtained, Mr. Adams prepared and published a severe and scrutinizing examination of its facts and suggestions, of the motives which prompted those who had brought it before the public, and of the discrepancies between the original and the alleged copy which Mr. Russell had volunteered to place in the office of the Secretary of State. Mr. Russell replied through the newspapers; on which reply Mr. Adams bestowed a searching and caustic analysis, commenting with great severity on his language and conduct.
The whole of this controversy was published immediately in an octavo pamphlet, including important documents relative to the subject and to the transactions of the commissioners at Ghent, by means of which Mr. Adams vindicates himself and his colleagues from the charges brought against them. This elaborate and powerful defence, on which the strength and character of his mind are deeply impressed, was regarded as triumphant.[9] ]
