Here the melancholy reflections consequent on his repeated and persistent failures suggested to him a very singular notion, that of contracting a partnership with God. He proceeded to enter seriously into this abnormal contract, and drew up an act in regular and technical form, which he transcribed into his day-book on September 24, 1719, in the following terms: “I have resolved to enter into a partnership with God, promising and undertaking to fulfil all the within-mentioned articles; and I enjoin my heirs, whoever they may be, to carry out these my intentions in case I should die before accomplishing them myself.” He then proceeds to declare that this association, the object of which is to deal in precious stones, shall hold good for five years, reckoning from October 2, 1719. He fixes his capital at 3000 Spanish piastres, about $3000, being all that remained to him of his patrimony. He binds himself not to enter into any other partnership during the five years, unless with a woman, by marriage. As soon as the five years shall have elapsed, he proposes to balance his accounts, to begin by withdrawing from the partnership the 3000 piastres with which he started; secondly, to take from it the dowry that his wife may have brought him; thirdly, any sum or sums that may have fallen in to him by succession or otherwise during the time; after which he adds, “And the surplus shall be equally divided between God and myself.” This unique partnership having been thus determined, Duhalde starts a third time for Spain, but the outset of this new attempt does not augur well for the partners. Two years after, however (1721), the project of a double marriage between the Courts of France and Spain gives a new impetus to the branch of commerce in which he is engaged, and he resolves to improve the opportunity. At last Fortune seems to smile upon his endeavors, and the ultimate results exceed his fondest hopes. He now returns to Paris, resolving to settle himself finally there. In 1722 he married the daughter of De Hansy, a well-known bookseller, who brought him 30,000 livres, and from his mother, who died in September of the same year, he inherited 70,226 livres. On May 20, 1723, a son was born to him. Meantime Duhalde never loses sight of the obligations he has taken upon himself toward his partner. He draws, from time to time, from the common fund, sums which he distributes in the name of God, to the poor, and inscribes these with regularity and precision in his registers.
