Sedge-grass rafts.
On some of the larger rivers of Africa, as the Okovango, discovered by our late friend C. J. Andersson, the Teoughe and others, rafts of sedge grass are used; sometimes these, if only intended to carry a few persons across a river, are small and comparatively manageable, and have even an attempt at comfort and security in a kind of rail raised round them of faggots of the same material. Others, used in hippopotamus hunting, are mere floats on which the small canoes are drawn up, and their chief merit is that they are so like natural accumulations that the animal does not think of getting out of their way.
On a still larger heap of these Mr. Andersson descended the tortuous course of the Teoughe for many miles; and Mr. Oscar T. Lindholm, who accompanied the eminent but unfortunate Swedish naturalist Wahlberg, gave us a most graphic account of a similar voyage. Immense quantities of sedge was collected, and bundles of it were thrown upon the water in some quiet nook, without any regularity and with no other fastening than its own natural cohesion and entanglement when one layer was thrown almost at random across another. A small hut was built upon the heap when it had acquired sufficient size, and the whole, when ready, was forced out into the stream, which brought it down at an average rate of two and a half miles per hour. If it took the ground, the only consequence was the loss of a few reeds from the bottom layer as the mass swung round and cleared itself. Snags, projecting points, or other impediments might tear off more, but nothing could stay the quiet but irresistible movement of the great raft, which, as the grass below became densely pressed and sodden, began to draw nearly 6ft. of water, and sank deeper every day; to remedy which, fresh grass was cut and thrown daily upon the upper layers. Frequently overhanging trees tore off portions, and once a large trunk lay so close to the water that it fairly swept the decks fore and aft; the occupants saved themselves by climbing over the tree, but the hut, with many valuables, was carried right away. With this exception the voyage was accomplished safely, but it was a task of great difficulty to prevent the unwieldy mass being swept by the stream into Lake Ngami, in the still waters of which it might have floated for an indefinite period without coming nearer to the shore.
The obelisk of Luxor was removed by laying a vessel ashore, with her head towards it, when the river was at its highest; the masts were lifted and shored up from the deck, so as to allow an immense packing case to be built upon the keelson; ways like those for launching a ship were built, and on them the heavy monolith was forced onward till it lay at length fairly in the vessel, occupying nearly her entire length; a deep channel cut from the vessel to the river, and at the next rise of the water she floated off. But without forgetting this, we do not remember a case of more ingenious and persevering adaptation of apparently insufficient means to great and important ends, than that of the conveyance by our countryman Layard of the great human-headed bulls and lions from the magnificent ruins in which he found them to the point of embarkation on the Tigris, and thence, by rafts so frail that we almost wonder how the ponderous masses were supported, to a place where vessels more adequate to the carriage of such a burden could receive them. It would be a pity to curtail the brief and graphic description, and we therefore give it in his own words:—
“I did not doubt that the skins, once blown up, would support the sculptures without difficulty as far as Baghdad. The journey would take eight or ten days, under favourable circumstances. But there they would require to be opened and refilled, or the rafts would scarcely sustain so heavy a weight all the way to Busrak; the voyage from Baghdad to that port being considerably longer, in point of time, than that from Mosul to Baghdad. However carefully the skins are filled, the air gradually escapes. Rafts bearing merchandise are generally detained several times during their descent to enable the raftmen to examine and refill the skins. If the sculptures rested upon only one framework, the beams being almost on a level with the water, the raftmen would be unable to get beneath them to reach the mouths of the skins, when they require replenishing, without moving the cargo. This would have been both inconvenient and difficult to accomplish; I was, therefore, desirous of raising the lion and bull as much as possible above the water, so as to leave room for the men to creep under them.
“It may interest the reader to know how these rafts, which have probably formed for ages the only means of traffic on the upper parts of the rivers of Mesopotamia, are constructed. The skins of full-grown sheep and goats are used. They are taken off with as few incisions as possible, and then dried and prepared. The air is forced in by the lungs through an aperture, which is afterwards tied up with string. A square framework, formed of poplar beams, branches of trees, and reeds, having been constructed of the size of the intended raft, the inflated skins are tied to it by osier and other twigs, the whole being firmly bound together. The raft is then removed to the water and launched. Care is taken to place the skins with their mouths upwards, that, in case any should burst or require filling, they can be easily opened by the raftmen. Upon the framework of wood are piled bales of goods and property belonging to merchants and travellers. When any person of rank or wealth descends the river in this fashion, small huts are constructed on the raft, by covering a common wooden “takht,” or bedstead of the country, with a hood formed of reeds and lined with felt. In these huts the travellers live and sleep during the journey. The poorer passengers seek shade or warmth by burying themselves amongst bales of goods and other merchandise, and sit patiently, almost in one position, until they reach their destination. They carry with them a small earthen “mangal,” or chafing-dish, containing a charcoal fire, which serves to light their pipes and to cook their coffee and food. The only real danger to be apprehended on the river is from the Arabs, who, when the country is in a disturbed state, invariably attack and pillage the rafts.
INFLATED FLOATS.
“The raftmen guide their rude vessels by long oars—straight poles, at the end of which a few split canes are fastened by a piece of twine. They skilfully avoid the rapids, and, seated on the bales of goods, work continually, even in the hottest sun. They will seldom travel after dark before reaching Tekrit, on account of the rocks and shoals which abound in the upper part of the river; but when they have passed that place they resign themselves, night and day, to the sluggish stream. During the floods in the spring, or after violent rains, small rafts may float from Mosul to Baghdad in about eighty-four hours; but the large rafts are generally six or seven days in performing the voyage. In summer, and when the river is low, they are frequently nearly a month in reaching their destination. When the rafts have been unloaded, they are broken up, and the beams, wood, and twigs are sold at a considerable profit, forming one of the principal branches of trade between Mosul and Baghdad. The skins are washed and afterwards rubbed with a preparation of pounded pomegranate skins, to keep them from cracking and rotting. They are then brought back, either upon the shoulders of the raftmen or upon donkeys, to Mosul or Tekrit, where the men engaged in navigation of the Tigris usually reside.”
