Thanks to the slave trade in past centuries, and the gin traffic in the present, our West Coast Settlements, instead of being bright jewels in the imperial crown of Britain, are at this day little better than standing monuments to her disgrace. Happily the closing years of this century are showing signs of an awakened public conscience. Governments, companies, and private merchants alike are taking a higher view of their responsibilities to barbarous races, and before another half century has come and gone we may hope to see the vile monster badly scotched if not killed. But while we gather from Park that in his day the slave trade was carried on by British merchants without a qualm of conscience, and that already gunpowder and gin formed the staple articles of barter for human flesh and blood, it is hardly less noteworthy that Islam was steadily making its beneficent influence felt throughout the whole land. He tells us that the inhabitants were divided into two great classes--the _Sonakies_ or spirit drinkers, and the _Bushreens_ or Mohammedans: the former, pagans sinking deeper and deeper in the scale of humanity under the degrading influence of European intercourse and commerce; the latter ever rising upward, adopting decent dress and decent behaviour, building mosques and establishing schools, and specially attempting to stem the flood of vile spirits poured into the country by Christian merchants. We have in a previous chapter alluded to the mighty revolution produced by Islam in the Central Sudan. Here we are only at the missionary outposts. Further inland, as we follow the footsteps of Park, we shall see more and more of the good work Mohammedanism had accomplished in Central Africa. Meanwhile it was not all study and observation with the young explorer. He had to go through a seasoning process of an unpleasant nature. Having on one occasion imprudently exposed himself to the night dew, he caught a fever, and while recovering had a second attack, which kept him a prisoner for some additional weeks. Thanks to the care of Dr. Laidley no evil consequences followed, while “his company and conversation beguiled the tedious hours during that gloomy season (the rains): when suffocating heats oppress by day, and when the night is spent by the terrified traveller in listening to the croaking of frogs, of which the numbers are beyond imagination, the shrill cry of the jackal, and the deep howling of the hyena--a dismal concert interrupted only by the roar of such tremendous thunder as no person can form a conception of but those who have heard it.” CHAPTER VII. _FROM THE GAMBIA TO THE SENEGAL._ The time had at last arrived for Park to start on his great undertaking.
