For a good view of the adjacent scenery, the hill, Baramuana, behind the village, was ascended. A caution was given about the probability of an attack of fever from a plant that grows near the summit. Dr. Kirk discovered it to be the _Paedevia foetida_, which, when smelt, actually does give headache and fever. It has a nasty fetor, as its name indicates. This is one instance in which fever and a foul smell coincide. In a number of instances offensive effluvia and fever seems to have no connection. Owing to the abundant rains, the crops in the Senna district were plentiful; this was fortunate, after the partial failure of the past two years. It was the 25th of April, 1860, before we reached Tette; here also the crops were luxuriant, and the people said that they had not had such abundance since 1856, the year when Dr. Livingstone came down the river. It is astonishing to any one who has seen the works for irrigation in other countries, as at the Cape and in Egypt, that no attempt has ever been made to lead out the water either of the Zambesi or any of its tributaries; no machinery has ever been used to raise it even from the stream, but droughts and starvations are endured, as if they were inevitable dispensations of Providence, incapable of being mitigated. Feeling in honour bound to return with those who had been the faithful companions of Dr. Livingstone, in 1856, and to whose guardianship and services was due the accomplishment of a journey which all the Portuguese at Tette had previously pronounced impossible, the requisite steps were taken to convey them to their homes.
