[Livingstone refers (on the 15th Dec.) to some writings he was engaged upon, and we find one of them here in his journal which takes the form of a despatch to Lord Clarendon, with a note attached to the effect that it was not copied or sent, as he had no paper for the purpose.  It affords an epitomised description of his late travels, and the stay at Casembe, and is inserted here in the place of many notes written daily, but which only repeat the same events and observations in a less readable form.  It is especially valuable at this stage of his journal, because it treats on the whole geography of the district between Lakes Nyassa and Moero, with a broad handling which is impossible in the mere jottings of a diary.]

    Town Of Casembe, 10th December, 1867..

    Lat. 9 deg. 37’ 13” South; long. 28 deg.  East.

    The Right Honourable the Earl of Clarendon.

My Lord,—­The first opportunity I had of sending a letter to the coast occurred in February last, when I was at a village called Molemba (lat. 10 deg. 14’ S.; long. 31 deg. 46’ E.), in the country named Lobemba.  Lobisa, Lobemba, Ulungu and Itawa-Lunda are the names by which the districts of an elevated region between the parallels 11 deg. and 8 deg. south, and meridians 28 deg.-33 deg. long. east, are known.  The altitude of this upland is from 4000 to 6000 feet above the level of the sea.  It is generally covered with forest, well watered by numerous rivulets, and comparatively cold.  The soil is very rich, and yields abundantly wherever cultivated.  This is the watershed between the Loangwa, a tributary of the Zambesi, and several rivers which flow towards the north.  Of the latter, the most remarkable is the Chambeze, for it assists in the formation of three lakes, and changes its name three times in the five or six hundred miles of its course.

On leaving Lobemba we entered Ulungu, and, as we proceeded northwards, perceived by the barometers and the courses of numerous rivulets, that a decided slope lay in that direction.  A friendly old Ulungu chief, named Kasonso, on hearing that I wished to visit Lake Liemba, which lies in his country, gave his son with a large escort to guide me thither; and on the 2nd April last we reached the brim of the deep cup-like cavity in which the Lake reposes.  The descent is 2000 feet, and still the surface of the water is upwards of 2500 feet above the level of the sea.  The sides of the hollow are very steep, and sometimes the rocks run the whole 2000 feet sheer down to the water.  Nowhere is there three miles of level land from the foot of the cliffs to the shore, but top, sides, and bottom are covered with well-grown wood and grass, except where the bare rocks protrude.  The scenery is extremely beautiful.  The “Aeasy,” a stream of 15 yards broad and thigh deep, came down alongside our precipitous path, and formed cascades by leaping 300 feet at a time.  These, with the bright
