REMARKS.—Air of Unyanyembe intensely dry; sometimes does not rain for months. Soil fertile by proximity of water; rains every 15 or 16 days. Lightning from S.E. We had very steady rain. Thunder and lightning like chota barsát in Upper India. About the 30th inst. country well sopped. All began to plant; rice about end of month, and Jawari after.

Rain, as at Zanzibar, every day. Generally deep cloudy morns. Cold wind, and very damp. Therm. 70°. Sun at 10 a.m., hot. Clouds partially dispersed. About 2 p.m. showers, with thunder and lightning, increase till dark, when become very violent. Bolts fell one night. Climate unwholesome as the Kinga-ni river. Almost all our men had fever. Wind generally E., but changing to S.W.

This rain in Dec. is called Muaka, or the year. We experienced it on the coast, in the Elphinstone, and the Riami. All are cultivating.

REMARKS.—Rains at Kazeh, began on 14th November.

At Ujiji about 2 months earlier. At Msene 1 month earlier.

Not heavy at first; no burst of monsoon, as in India, but invariably accompanied by violent thunder and lightning.

The sun of the rains is considered very sickly; it burns with a violent and nauseating heat, truly uncomfortable.

The wind during this month, N. after midnight till sunrise, when it becomes raw and cold. During the day warmer, and veered round to S.E. This was constant point. In evenings, and often at nights, it became a complete blast.

Direction of rain in Ujiji, generally either from N., from S.E., and from S.W. But it was, as everywhere, very variable. The S.E. and E. wind seems to prevail everywhere, from Ugogo to the Lake.

26, 27 On both these days tourbillons, or devils, of light dust,
filling houses.

28-31 Too sick to observe.

REMARKS.—Early summer. The earth is dried up with want of moisture; and in Unyanyembe the dews, except during the rains, are light.

The weather is monotonous. The morn cold, raw, and bright. The sun begins to tell at about 9 a.m., and at 10 a.m. rises a high wind from the N. and E., cooled by evaporation, and pouring from the hill-lines that flank the plains. It is considered very unwholesome. Fleecy clouds appear at noon, increase in volume and depth, and disappear about sunset, which is bright and clear, except when a thick cloud-bank occupies in straight line the western horizon. Nights often cool, and sometimes still and ‘muggy.’

The Kaus, or S.W. monsoon, is supposed to blow from April to the end of November, when it is succeeded for 4 months by the Kazkazi, or N.E. monsoon. Such are the seasons at Zanzibar. In Unyamwezi, however, the E. wind seems to last all the year.

REMARKS.—Midsummer. Despite the drought, beasts and birds begin to couple, and trees to put forth leaves.

The E. wind becomes milder, the weather better, especially at night, and the whirlwinds diminish. The change of seasons, which brought so much sickness, passed away in the latter third of July. In Sept., Unyamwezi is tolerably healthy.

The normal day, at this season, is a cold high E. wind, rising shortly after the sun has heated the ground. It pours from the far Usagara Mountains. The sky is clear and sparkling, with a few high cirri, and on the horizon white cumuli. Shortly after noon clouds obscure the sun and confine the wind, which, however, sometimes blow throughout the evening and the night. The nights are cool about 11 p.m., till which hour the air is still, warm, and genial. It much resembles the end of an Italian summer day. The winds, however, with their prodigious loads of dust, if a little less puffy, and more continuous, would rival the gales of Sind.

REMARKS.—Thermometer suspended in tent, fronting north, as before.

Weather very variable. In Ugogi and Eastern Usagara the Rainy Monsoon appears to have set in on the 6th Dec., 1858.

Until Maroro, the climate had the aspect of the rainy seasons. After that meridian, throughout Eastern Usagara the weather held up; but these masses of hills seem rarely, if ever, to be without rain. The dews are remarkably heavy, forming a contrast with Unyamwezi and the inland regions.

At Zungomero, reached about the end of December, the violent showers which fell like buckets-full, piercing at once the thickest thatches, were called by the people the ‘Sowing Rains.’ All were busy in the fields, and labour was protracted till about the first week in December.

The sea-breeze extends to Zungomero, setting in at 9 to 10 a.m. In foul weather sea-gulls are blown up from the coast. The vicinity of the Duthumi hills to the N. E., which are rarely, if ever, seen in a clear outline, and the mountains of Usagara westward, render this a region of almost perpetual rain. Its summer lasts about one fortnight, beginning in early January, at which time no rain falls.

OBSERVATIONS MADE IN KHUTU AND UZARAMO, DURING THE MONTHS OF JANUARY
AND FEBRUARY, 1859.

REMARKS.—An anomaly was observed at Zungomero. There appeared to be a double sea-breeze, the earlier set in between 9 and 10 a.m. every day. The second rose regularly at sunset, and at times there were gusts from the eastward at night. This phenomenon appears purely local, and caused by the cold winds of the Duthumi hills, which, when the sun disappears, find their way to the still heated head of the Khutu Valley.

Between Zungomero and the Mgeta Ford the sea-breeze is lost in the lower levels. After the Mgeta it sets in strong and regular. The rain also diminishes, though in winter tourbillons are common. When the E. wind blows cold it is a sign that rain is approaching, like the puffs preceding storms on the Zanzibar seas.

Rain in showers not common on the land above the ancient sea-beach; when on the shore there is more. This accounts for superior fertility.

Wind at Konduchi as on the coast generally. Calm morn till 9 or 10 a.m. Sea-breeze till sunset. Calm again till fetid land-breeze sets in at night, and endures until morn.
