Frequent showers fell on our way up the Zambesi, in the beginning of August. On the 8th we had upwards of three inches of rain, which large quantity, more than falls in any single rainy day during the season at Tette, we owed to being near the sea. Sometimes the cabin was nearly flooded; for, in addition to the leakage from below, rain poured through the roof, and an umbrella had to be used whenever we wished to write: the mode of coupling the compartments, too, was a new one, and the action of the hinder compartment on the middle one pumped up the water of the river, and sent it in streams over the floor and lockers, where lay the cushions which did double duty as chairs and beds. In trying to form an opinion of the climate, it must be recollected that much of the fever, from which we suffered, was caused by sleeping on these wet cushions. Many of the botanical specimens, laboriously collected and carefully prepared by Dr. Kirk, were destroyed, or double work imposed, by their accidentally falling into wet places in the cabin. About the middle of August, after cutting wood at Shamoara, we again steamed up the Shire, with the intention of becoming better acquainted with the people, and making another and longer journey on foot to the north of Lake Shirwa, in search of Lake Nyassa, of which we had already received some information, under the name Nyinyesi (the stars). The Shire is much narrower than the Zambesi, but deeper, and more easily navigated. It drains a low and exceedingly fertile valley of from fifteen to twenty miles in breadth. Ranges of wooded hills bound this valley on both sides. For the first twenty miles the hills on the left bank are close to the river; then comes Morambala, a detached mountain 500 yards from the river's brink, which rises, with steep sides on the west, to 4000 feet in height, and is about seven miles in length. It is wooded up to the very top, and very beautiful. The southern end, seen from a distance, has a fine gradual slope, and looks as if it might be of easy ascent; but the side which faces the Shire is steep and rocky, especially in the upper half. A small village peeps out about halfway up the mountain; it has a pure and bracing atmosphere; and is perched above mosquito range. The people on the summit have a very different climate and vegetation from those of the plains; but they have to spend a great portion of their existence amidst white fleecy clouds, which, in the rainy season, rest daily on the top of their favourite mountain. We were kindly treated by these mountaineers on our first ascent; before our second they were nearly all swept away by Mariano. Dr. Kirk found upwards of thirty species of ferns on this and other mountains, and even good-sized tree-ferns; though scarcely a single kind is to be met with on the plains. Lemon and orange trees grew wild, and pineapples had been planted by the people. Many large hornbills, hawks, monkeys, antelopes,
