The peculiarities which affect the growth of the acacia appear to be transmitted to a very remarkable extent. On a former journey I took some seeds to Cairo, which already had produced some trees of a very considerable size. These trees exhibited the special appearances of the parents; below the prickles were the same excrescences and insect-borings; not only was this the case in the park of Esbekieh in Cairo, but it also occurred in several other situations, which left the problem to be solved, how was it that the insect survived in the seed, or how did it contrive to get to its tree in Cairo?

ABOO SAMMAT.

On the 5th of February we finally left the Egyptian encampment, and directed our course up the stream towards the region of the papyrus. After sailing all night we stopped just short of the mouth of the Sobat, on the right bank close to a forest. The progress of the coming days would lead us through an insecure territory; we wanted to make up our supply of wood, and knew that the hostility of the Shillooks would, in many places, render any attempt at landing on our part quite unadvisable. Of the boats which were bound for the Gazelle, only one had arrived. In order to render us assistance, the Mudir had charged the owner not to leave my party in the lurch. This circumstance had a very important effect upon my whole journey, as it was the means of introducing me to Mohammed Aboo Sammat, who was proprietor of the boat. This magnanimous Nubian was destined to exercise a very considerable influence on my undertaking, and, indeed, he contributed more to my success than all the satraps of the Soudan. During my land journey I had first made his acquaintance, and now he invited me to be his guest until he should have accompanied me to the remotest tribes, a proposal on his part which made my blood tingle in my veins. A native of Dar-Kenoos, in his way he was a little hero. Sword in hand he had vanquished various districts large enough to have formed small states in Europe. A merchant full of enterprise, he avoided no danger, and was sparing neither of trouble nor of sacrifice; in the words of the Horaz, “he explored the distant Indies, and compassed sea and land to escape poverty.” Yet all the while he had the keenest sympathy with learning, and could travel through the remotest countries at the bidding of science to see the wonders of the world.

Far as eye can see, the Sobat flows between level banks bounded by unlimited steppes; where it joins the Nile it is about half as broad as the main stream. For a considerable distance the cloudy milk-white waters, which indicate the mountain stream, can be distinguished as they roll into the deep azure of the White Nile. The Sobat water is, however, far preferable to the Nile water, which, after being strained as it were, through a filter of grass, emerges transparent in colour, but with a flat, earthy flavour, which is highly disagreeable to the palate. The effect of the commingling of the two streams can be distinctly traced as far as Fashoda, where the inhabitants fancy they enjoy some consequent sanitary advantage.

We kept quite close to the right bank of the uninhabited quarter, but on the same day we found ourselves in full flight before thousands of the native Shillooks, who, with their light canoes of ambatch, hastened to the bank, and in thick troops prepared to displace us. As fate would have it, just as we were within sight of the dreaded Shillooks, our sailyard broke, and we were compelled to seek the land. Soon rose the cry, “They are coming! they are coming!” for in fact we could see them dashing over the stream with incredible celerity, and crowding their canoes as thick as ants. Hardly had we regained our craft, and made some speedy preparations for defence against an attack, when the foremost of the Shillook men, equipped for war, carrying their tufted lances in their hands, showed themselves by the banks which only now we had quitted. Apparently they came to offer some negotiation with us in the way of traffic; but ours was the ancient policy, “Danaos timentes,” and we pushed on.

Although, including Aboo Saramat’s party, we numbered full eighty armed men, we could not help suspecting that as soon as the north-east breeze should drop, by whose aid we were going along the stream without a sail, the savages would take advantage of our bad situation and inadequate fighting force to make an attack upon us.

IN FULL FLIGHT BEFORE THE SHILLOOK CANOES.

A HASTY RETREAT.
