The steamer reached Tette on the 23rd of June, and, after undergoing repairs, proceeded to the Kongone to receive provisions from one of H.M. cruisers. We had been very abundantly supplied with first-rate stores, but were unfortunate enough to lose a considerable portion of them, and had now to bear the privation as best we could. On the way down, we purchased a few gigantic cabbages and pumpkins at a native village below Mazaro. Our dinners had usually consisted of but a single course; but we were surprised the next day by our black cook from Sierra Leone bearing in a second course. “What have you got there?” was asked in wonder. “A tart, sir.” “A tart! of what is it made?” “Of cabbage, sir.” As we had no sugar, and could not “make believe,” as in the days of boyhood, we did not enjoy the feast that Tom’s genius had prepared. Her Majesty’s brig “Persian,” Lieutenant Saumarez commanding, called on her way to the Cape; and, though somewhat short of provisions herself, generously gave us all she could spare. We now parted with our Kroomen, as, from their inability to march, we could not use them in our land journeys. A crew was picked out from the Makololo, who, besides being good travellers, could cut wood, work the ship, and required only native food.
While at the Kongone it was found necessary to beach the steamer for repairs. She was built of a newly invented sort of steel plates, only a sixteenth of an inch in thickness, patented, but unfortunately never tried before. To build an exploring ship of untried material was a mistake. Some chemical action on this preparation of steel caused a minute hole; from this point, branches like lichens, or the little ragged stars we sometimes see in thawing ice, radiated in all directions. Small holes went through wherever a bend occurred in these branches. The bottom very soon became like a sieve, completely full of minute holes, which leaked perpetually. The engineer stopped the larger ones, but the vessel was no sooner afloat, than new ones broke out. The first news of a morning was commonly the unpleasant announcement of another leak in the forward compartment, or in the middle, which was worse still.
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.
