I have just received information that a plough addressed to me has arrived at New York, _from England_, but unaccompanied by any letter or other explanation. As I have had no intimation of such an article to be forwarded to me from that country, I presume it is the one sent by the Society of the Seine, that it has been carried into England under their orders of council, and permitted to come on from thence. This I shall know within a short time. I shall with great pleasure attend to the construction and transmission to the Society of a plough with my mould board. This is the only part of that useful instrument to which I have paid any particular attention. But knowing how much the perfection of the plough must depend, 1st, on the line of traction; 2d, on the direction of the share; 3d, on the angle of the wing; 4th, on the form of the mould-board; and persuaded that I shall find the three first advantages eminently exemplified in that which the Society sends me, I am anxious to see combined with these a mould-board of my form, in the hope it will still advance the perfection of that machine. But for this I must ask time till I am relieved from the cares which have now a right to all my time, that is to say, till the next Spring. Then giving, in the leisure of retirement, all the time and attention this construction merits and requires, I will certainly render to the Society the result in a plough of the best form I shall be able to have executed. In the meantime, accept for them and yourself the assurances of my high respect and consideration. TO MR. LASTEYRIE. WASHINGTON, July 15, 1808.
