In 1801 the negotiations with the Government relative to the New South Wales mission were resumed. A visit to London was found necessary for a satisfactory discussion of the matter, and accordingly we find Park in the metropolis in the early spring. How deep and tender was his affection for his winsome wife is shown in a letter written to her during the visit--one of the few glimpses that have come down to us of the more private side of the explorer’s character. The letter is dated March 12th, 1801, and is as follows:-- “MY LOVELY AILIE,--Nothing gives me more pleasure than to write to you, and the reason why I delayed it a day last time was to get some money to send to you. You say you are wishing to spend a note upon yourself. My sweet Ailie, you may be sure I approve of it. What is mine is yours, and I receive much pleasure from your goodness in consulting me about such a trifle. I wish I had thousands to give you, but I know that my Ailie will be contented with what we have, and we shall live in the hope of seeing better days. I long very much to be with you, my love, and I was in great hopes of having things settled before now, but Sir Joseph (Banks) is ill, and I can do nothing till he recovers. “I am happy to know you will go to New South Wales with me, my sweet wife. You are everything that I could desire; and wherever we go, you may be sure of one thing, that I shall always love you. Whenever I have fixed on this or any other situation I shall write to you. In the meantime, let nobody know till things are settled, as there is much between the cup and the lip. “My lovely Ailie, you are constantly in my thoughts. I am tired of this place, but cannot lose the present opportunity of doing something for our advantage. When that is accomplished I shall not lose one moment. My darling, when we meet I shall be the happiest man on earth. Write soon, for I count the days till I hear from you, my lovely Ailie.” Again the negotiations with the Government fell through, and there was nothing for it but for Park to return once more to Foulshiels disappointed and discouraged, but possessed more than ever by the fever of unrest--more and more under the influence of the Niger magnet--against which the sole counteracting forces were love for his wife, the dread of being separated from her, and his duty as a husband.
