A man of indefatigable industry, he has published many books, the most widely read of these being 'Natural Law in the Spiritual World' a study of psychological conditions from the point of view of the Evolutionist. This work has passed through a large number of editions, and been translated into French, German, Dutch, and Norwegian. Scarcely less popular were 'The Greatest Thing in the World' (love), and 'Pax Vobiscum.' In 1894 he published a volume called 'The Ascent of Man,' in which he insists that certain altruistic factors modify the process of Natural Selection. This doctrine elicited much critical commentary from the stricter sects of the scientists, but the new view commended itself at once to the general reader. The citations here given are selected from Mr. Drummond's book of travels, 'Tropical Africa,' a book whose simplicity and vividness enable the reader to see the Dark Continent exactly as it is. THE COUNTRY AND ITS PEOPLE From 'Tropical Africa' Nothing could more wildly misrepresent the reality than the idea of one's school days that the heart of Africa is a desert. Africa rises from its three environing oceans in three great tiers, and the general physical geography of these has been already sketched:--first, a coast line, low and deadly; farther in, a plateau the height of the Scottish Grampians; farther in still, a higher plateau, covering the country for thousands of miles with mountain and valley. Now fill in this sketch, and you have Africa before you. Cover the coast belt with rank yellow grass; dot here and there a palm; scatter through it a few demoralized villages; and stock it with the leopard, the hyena, the crocodile, and the hippopotamus. Clothe the mountainous plateaux next, both of them, with endless forests; not grand umbrageous forest like the forests of South America, nor matted jungle like the forests of India, but with thin, rather weak forest,--with forest of low trees, whose half-grown trunks and scanty leaves offer no shade from the tropical sun. Nor is there anything in these trees to the casual eye to remind you that you are in the tropics. Here and there one comes upon a borassus or fan-palm, a candelabra-like euphorbia, a mimosa aflame with color, or a sepulchral baobab. A close inspection also will discover curious creepers and climbers; and among the branches strange orchids hide their eccentric flowers. But the outward type of tree is the same as we have at home--trees resembling the ash, the beech, and the elm, only seldom so large except by the streams, and never so beautiful. Day after day you may wander through these forests, with nothing except the climate to remind you where you are. The beasts to be sure are different, but unless you watch for them you will seldom see any; the birds are different, but you rarely hear them; and as for the rocks, they are our own familiar gneisses and granites, with honest basalt dikes boring through them, and
