Whatever might be the opinion of Park as to the quality of his troops, of which he appears to have formed a very erroneous estimate, he must at least have been fully aware of the disadvantage arising from the near approach of the great tropical rains. But his situation was critical; and he had only a choice of difficulties. He might either attempt (what he might perhaps consider as being just _possible_) to reach the Niger before the rainy season should be completely set in; or he might postpone his journey till the return of the proper season for travelling, which would be in November or December following. The event has shewn that he would have acted more wisely in deferring the expedition. But the motives which might lead him to a contrary determination, were obvious and powerful; and will be found, on the whole, sufficient for the justification of his conduct. He must naturally have considered that the postponement of the expedition _for seven months_, besides being in the greatest degree irksome both to himself and the companions of his journey, would occasion a great additional expense, and disappoint the expectations of Government; and he might perhaps entertain doubts, since the case was not provided for by his official instructions, whether he should altogether escape censure, if he should postpone his journey for so long a period, under any circumstances much short of a positive and undoubted necessity. In this difficult situation, he adopted that alternative which was most congenial to his character and feelings; and having once formed this resolution, he adhered to it with tranquillity and firmness; dismissing from his own mind all doubts and apprehensions, or at least effectually concealing them, from the companions of his journey, and from his friends and correspondents in England. * * * * * For the particulars of this second expedition, the reader must be referred to the Journal now published, which commences from this period. But in order to give a general view of the extent of Park's labours, it may be useful on this, as on the former occasion, to note the more important dates, and some of the principal circumstances of the journey. The persons composing the expedition, being assembled at Kayee, a small town on the Gambia a little below Pisania, Park engaged a Mandingo priest, named Isaaco, who was also a travelling merchant and much accustomed to long inland journies, to serve as the guide to his caravan. On the 27th of April 1805, he took his departure from Kayee, and arrived in two days at Pisania, from whence he had set out for the interior of Africa nearly ten years before. Some of the practical difficulties of the march were apparent during this short journey: and he found it necessary to stop at Pisania six days (a delay which must have been highly inconvenient), to purchase additional beasts of burden, and make other arrangements for the expedition.
