1To James Madison from Horatio Gates Spafford, 18 February 1815 (Madison Papers)
Permit me to present my congratulations on the prospect of peace. Anxious to have the principles of my invention, in the construction of wheel-carriages, fairly & fully tested, I now send, enclosed, a Certificate of a single Right to make use of the improvement. I sent, some days since, the little pamphlet on that subject. Should it not be thy wish to use the Right I send, please hand it to...
2To James Madison from Horatio Gates Spafford, 7 January 1811 (Madison Papers)
I ought, perhaps, to apologize, for troubling thee with a subject of so little direct concern to thyself, as that I am now about to propose, for thy consideration. The details, which the 3rd Census will afford, aught to be embodied, in a Volume of convenient size, & published for general use; & unless some other person shall have effected this previous to next 6 Mo., (June,) I contemplate...
3To James Madison from Horatio Gates Spafford, 13 September 1814 (Madison Papers)
At the moment of taking my pen to address thee, my eyes are flowing with tears of anxiety and deep distress for the situation of my beloved country. And when I grieve for that, I grieve also for myself. Perhaps thy time may hardly allow thee to peruse this, but let me entreat, if that may be possible. Devoted, as I feel, to the interests of America, my passions almost subdue, at times, my...
4To James Madison from Horatio Gates Spafford, 16 December 1814 (Madison Papers)
A part of the object of my journey to Washington, was suspended in part, in consequence of the feeble state of thy health. It was my intention, (as I believe I intimated to thee,) to inform thee particularly of an important discovery of mine, & to ask thy aid in my wishes to obtain an exclusive right, by a special law, & for a longer term than is authorised by ordinary Patents. When I spoke...
5To James Madison from Horatio Gates Spafford, 12 July 1810 (Madison Papers)
I take the liberty to address one of these Letters to thee, because I can but suppose thou must feel an interest in every undertaking which interests & affects the community. Placed, as thou art, at the civil head of a Nation of Freemen, thy fatherly goodwill embraces, I trust, an anxious regard for the whole—& while I thus regard thee, I could but wish to engage thy attention to what is doing...
6To James Madison from Horatio Gates Spafford, 15 June 1814 (Madison Papers)
I know not what may be the views of Administration, but I have taken upon myself to deny that those in whom the national trust is deposited to guard the Constitution, should be the first to design its overthrow. To cover real designs, it is not uncommon to impute to opponents in political life, purposes which we intend. It is said by many & by many believed, that our government will soon be...
7To James Madison from Horatio Gates Spafford, 23 January 1817 (Madison Papers)
Had I not a great personal interest in seeing the Laws of the United States, relating to the granting of Patents, & the protection of the rights of Inventors, So Modified as to embrace a better security of these rights, I should not have devoted So much time & attention to this Subject: nor should I now presume to Solicit thy attention to it. The Essay of “Franklin,” published in Nos. 8 & 9 of...
8To James Madison from Horatio Gates Spafford, 18 April 1816 (Madison Papers)
I wrote thee, some time since, concerning an Essay of mine, which I proposed to have sent to thee for examination, before I should publish it: & I am now to explain why that Paper was not sent to thee as I intended. Presuming thy time would be all occupied at that time, I sent it to thy friend Jefferson to read, requesting him to return it to thee, as soon as might be convenient, & to favor me...
9To James Madison from Horatio Gates Spafford, 25 December 1815 (Madison Papers)
I have this day forwarded, by Mail, to the late President Jefferson, for his examination, a long Essay on the propriety of establishing a National School of Science & the Mechanic Arts, at the seat of the National Government; & on a Reform of the Patent System, of the United States. It was my intention to offer this first for thy perusal, but reflecting that thy time could probably be more...
