Here Frank paused and announced an intermission of ten minutes, to enable the reader to rest a little. During the intermission the youths discussed what they had heard, and agreed unanimously that the description of Zanzibar and its people and their ruler was very interesting.

Before the reading was resumed, one of the youths asked if Zanzibar was the usual starting-point for expeditions for the exploration of Africa. Mr. Stanley was absent at the moment the question was asked, but the answer was readily given by Doctor Bronson. "Zanzibar is the usual starting-point," said the Doctor, "but it is by no means the only one. Livingstone's expedition for exploring the Zambesi River set out from Zanzibar, and so did other expeditions of the great missionary. Burton and Speke started from there in 1856, when they discovered Lake Tanganika; and, four years later, Speke and Grant set out from the same place. Lieutenant Cameron, in his journey across Africa, made Zanzibar his starting point; and the expedition of Mr. Johnson to the Kilimandjaro Mountain was chiefly outfitted there, though it left the coast at Mombasa. "Zanzibar," continued Doctor Bronson, "is the best point of departure for an inland expedition anywhere along the east coast of Africa, for the reason that it is the largest and most important place of trade. Its shops are well supplied with the goods that an explorer needs for his journey, and its merchants have a better reputation than those of other African ports. Everything in the interior of Africa must be carried on the backs of men, there being, as yet, no other system of transportation. Horses cannot live in certain parts of the interior of Africa, owing to the tsetse-fly, which kills them with its bites; and even were it not for this fly, it is likely that the heat of the climate would render them of little use. Occasionally, a traveller endeavors to use donkeys as beasts of burden, but these animals are scarce and dear, and of much less use than in other lands. Until Africa is provided with railways--and that will not be for a long while yet--the transportation must be done by men. Every caravan that leaves the coast for the interior of the continent requires a large number of porters; and the difficulty of obtaining them is one of the greatest annoyances to merchants and travellers."
