Nothing was effectually done, on the subject of the Smithsonian fund, until the 22d of April, 1846, when a bill to carry into effect that bequest was reported by Mr. Owen, of Indiana, and earnestly supported by him and others. In its important general features it coïncided with the views of Mr. Adams, except only that it made no provision for an Astronomical Observatory. After various amendments, it received the sanction of both houses of Congress, Mr. Adams voting in its favor. On the 10th of August, 1846, it received the signature of the President of the United States.

During the debate upon this bill, its supporters acknowledged "that Mr. Adams had labored in this good cause with more zeal and perseverance than any other man."

In the course of the same debate it was said by one member that, "inasmuch as the views of Mr. Adams had been carried out in respect of an Astronomical Observatory, by the government, in the District of Columbia,"—and by another, that, "as building light-houses in the skies had grown into popular favor,"—it was hoped he would find no difficulty in giving his vote for the bill. On which Mr. Adams observed, that "he was very glad to hear that the 'building light-houses in the skies had grown into popular favor.' The appropriation for this Astronomical Observatory had been clandestinely smuggled into the law, under the head of a dépôt for charts, when, a short time before, a provision had been inserted in a bill passed that no appropriation should be applied to an Astronomical Observatory. He claimed no merit for the erection of an Astronomical Observatory, but, in the course of his whole life, no conferring of honor, of interest, or of office, had given him more delight than the belief that he had contributed, in some small degree, to produce these Astronomical Observatories both here and elsewhere.[48] ] He no longer wished any portion of the Smithsonian fund to be applied to an Astronomical Observatory."

Notwithstanding this disclaimer, the four reports of Mr. Adams, on the Smithsonian fund, in 1836, 1840, 1842, and 1844, which were neither coïncident with the views nor within the comprehension of his opponents, will remain imperishable monuments of the extent and elevation of his mind on this subject. When the continued and strenuous exertions with which Mr. Adams opposed, at every step, the efforts to convert that fund to projects of personal interest or ambition are appreciated, it will be evident that the people of the United States owe to him whatever benefit may result from the munificence of James Smithson. History will be just to his memory, and will not fail to record his early interest and strenuous zeal for the advancement of astronomical science, and the influence his eloquence and untiring perseverance, in illustrating its importance with an unsurpassed array of appropriate learning, exerted on the public mind in the United States, not only in effecting the establishment of other Astronomical Observatories, but absolutely compelling party spirit, notwithstanding its open, bitter animosity, to lay the foundation of that Observatory which now bears the name of "National."

In February, 1843, Andrew Jackson addressed a letter to Aaron Vail Brown, a member of Congress, strongly recommending the annexation of Texas, and giving his reasons for that measure, which he commenced by stating the following facts:

"Soon after my election, in 1829, it was made known to me by Mr. Erwin, formerly our minister at the court of Madrid, that whilst at that court he had laid the foundation of a treaty with Spain for the cession of the Floridas, and the settlement of the boundary of Louisiana, fixing the western limit of the latter at the Rio Grande, agreeably to the understanding of France; that he had written home to our government for power to complete and sign this negotiation; but that, instead of receiving such authority, the negotiation was taken out of his hands, and transferred to Washington, and a new treaty was there concluded, by which the Sabine, and not the Rio Grande, was recognized and established as the boundary of Louisiana. Finding that these statements were true, and that our government did really give up that important territory, when it was at its option to retain it, I was filled with astonishment. The right to the territory was obtained from France, Spain stood ready to acknowledge it to the Rio Grande, and yet the authority asked by our minister to insert the true boundary was not only withheld, but, in lieu of it, a limit was adopted which stripped us of the whole vast country lying between the two rivers."

The letter containing this statement Aaron Vail Brown kept concealed from the public until March, 1844, when he gave it publicity to counteract a letter from Mr. Webster against the annexation of Texas to the United States. This statement of Andrew Jackson having thus been brought to the knowledge of Mr. Adams, he took occasion, on the 7th of October in that year, in an address to a political society of young men in Boston, to contradict and expose it in the following terms:

"I have read the whole of this letter to you, for I intend to prolong its existence for the benefit of posterity." [After reading the above extract from the letter of Andrew Jackson, Mr. Adams proceeds.] "He was filled with astonishment, fellow-citizens! I am repeating to you the words of a man who has been eight years President of the United States; words deliberately written, and published to the world more than a year after they were written; words importing a statement of his conduct in his office as chief magistrate of this Union; words impeaching of treason the government of his predecessor, James Monroe, and in an especial manner, though without daring to name him, the Secretary of State,—a government to which he (Andrew Jackson) was under deep obligations of gratitude.

"In what language of composure or of decency can I say to you that there is in this bitter and venomous charge not one single word of truth; that it is from beginning to end grossly, glaringly, wilfully false?—false even in the name of the man from whom he pretends to have derived his information. There never was a minister of the United States in Spain by the name of Erwin. The name of the man who went to him on this honorable errand, soon after his election in 1829, was George W. Erving, of whom and of whose revelations I shall also have something to say. I do not charge this distortion of the name as wilfully made; but it shows how carelessly and loosely all his relations and intercourse with him hung upon his memory, and how little he cared for the man.

"The blunder of the name, however, is in itself a matter of little moment. Mr. George W. Erving never did make to Mr. Jackson any such communication as he pretends to have found true, and to have filled him with astonishment. Mr. Erving never did pretend, nor will he dare to affirm, that he had laid the foundation of a treaty with Spain for the cession of the Floridas, and the settlement of the boundary of Louisiana, fixing the western limit at the Rio Grande. The charge, therefore, that our government did really give up that important territory, when it was at its option to retain it, is purely and unqualifiedly untrue; and I now charge that it was known by Mr. Brown to be so when he published General Jackson's letter; for, in the postscript to Jackson's letter, he says 'the papers furnished by Mr. Erwin, to which he had referred in it, could be placed in Mr. Brown's possession, if desired.'
