The most pleasant sight I witnessed at Senna was the negroes of Senhor Isidore building boats after the European model, without any one to superintend their operations.  They had been instructed by a European master, but now go into the forest and cut down the motondo-trees, lay down the keel, fit in the ribs, and make very neat boats and launches, valued at from 20 Pounds to 100 Pounds.  Senhor Isidore had some of them instructed also in carpentry at Rio Janeiro, and they constructed for him the handsomest house in Kilimane, the woodwork being all of country trees, some of which are capable of a fine polish, and very durable.  A medical opinion having been asked by the commandant respecting a better site for the village, which, lying on the low bank of the Zambesi, is very unhealthy, I recommended imitation of the Jesuits, who had chosen the high, healthy mountain of Gorongozo, and to select a new site on Morumbala, which is perfectly healthy, well watered, and where the Shire is deep enough for the purpose of navigation at its base.  As the next resource, I proposed removal to the harbor of Mitilone, which is at one of the mouths of the Zambesi, a much better port than Kilimane, and where, if they must have the fever, they would be in the way of doing more good to themselves and the country than they can do in their present situation.  Had the Portuguese possessed this territory as a real colony, this important point would not have been left unoccupied; as it is, there is not even a native village placed at the entrance of this splendid river to show the way in.

On the 9th of May sixteen of my men were employed to carry government goods in canoes up to Tete.  They were much pleased at getting this work.  On the 11th the whole of the inhabitants of Senna, with the commandant, accompanied us to the boats.  A venerable old man, son of a judge, said they were in much sorrow on account of the miserable state of decay into which they had sunk, and of the insolent conduct of the people of Kisaka now in the village.  We were abundantly supplied with provisions by the commandant and Senhor Ferrao, and sailed pleasantly down the broad river.  About thirty miles below Senna we passed the mouth of the River Zangwe on our right, which farther up goes by the name of Pungwe; and about five miles farther on our left, close to the end of a low range into which Morumbala merges, we crossed the mouth of the Shire, which seemed to be about 200 yards broad.  A little inland from the confluence there is another rebel stockade, which was attacked by Ensign Rebeiro with three European soldiers, and captured; they disarmed the rebels and threw the guns into the water.  This ensign and Miranda volunteered to disperse the people of Kisaka who were riding roughshod over the inhabitants of Senna; but the offer was declined, the few real Portuguese fearing the disloyal half-castes among whom they dwelt.  Slavery and immorality have here done their work; nowhere
