"I suggest these matters that the senate may not be taken unawares, for I think it not improbable that some Fed, who intends to negative the cession, will move to take it up as if it were a Treaty of Alliance or of Navigation and Commerce. "The object here is an increase of territory for a valuable consideration. It is altogether a home concern--a matter of domestic policy. The only real ratification is the payment of the money, and as all verbal ratification without this goes for nothing, it would be a waste of time and expense to debate on the verbal ratification distinct from the money ratification. The shortest way, as it appears to me, would be to appoint a committee to bring in a report on the President's Message, and for that committee to report a bill for the payment of the money. The french Government, as the seller of the property, will not consider anything ratification but the payment of the money contracted for. "There is also another point, necessary to be aware of, which is, to accept it in toto. Any alteration or modification in it, or annexed as a condition is so far fatal, that it puts it in the power of the other party to reject the whole and propose new Terms. There can be no such thing as ratifying in part, or with a condition annexed to it and the ratification to be binding. It is still a continuance of the négociation. "It ought to be presumed that the American ministers have done to the best of their power and procured the best possible terms, and that being immediately on the spot with the other party they were better Judges of the whole, and of what could, or could not be done, than any person at this distance, and unacquainted with many of the circumstances of the case, can possibly be. "If a treaty, a contract, or a cession be good upon the whole, it is ill policy to hazard the whole, by an experiment to get some trifle in it altered. The right way of proceeding in such case is to make sure of the whole by ratifying it, and then instruct the minister to propose a clause to be added to the Instrument to obtain the amendment or alteration wished for. This was the method Congress took with respect to the Treaty of Commerce with France in 1778. Congress ratified the whole and proposed two new articles which were agreed to by France and added to the Treaty. "There is according to newspaper account an article which admits french and Spanish vessels on the same terms as American vessels. But this does not make it a commercial Treaty. It is only one of the Items in the payment: and it has this advantage, that it joins Spain with France in making the cession and is an encouragement to commerce and new settlers. "With respect to the purchase, admitting it to be 15 millions dollars, it is an advantageous purchase. The revenue alone purchased as an annuity or rent roll is worth more--at present I suppose the revenue will pay five per cent for the purchase money.
