Jan. 16th.--A new dish! There is no longer mock-turtle soup--REAL turtle is MOCK HIPPOPOTAMUS. I tried boiling the fat, flesh, and skin together, the result being that the skin assumes the appearance of the green fat of the turtle, but is far superior. A piece of the head thus boiled, and then soused in vinegar, with chopped onions, cayenne pepper, and salt, throws brawn completely in the shade. My men having revelled in a cauldron of hippopotamus soup, I serve out grog at sunset, all ships being together. Great contentment, all appetites being satisfied. The labour of towing through swamps, tugging by the long grass, and poling against a strong current, is dreadful, and there appears to be no end to this horrible country. "On dit," that during the dry season there is plenty of game near the river, but at present boundless marshes devoid of life, except in the shape of mosquitoes, and a very few water-fowl, are the only charms of the White Nile. The other day I caught one of the men stealing the salt; Richarn having been aware of daily thefts of this treasure, and having failed to report them, the thief received twenty with the coorbatch, and Richarn is reduced to the ranks, as I anticipated. No possibility of taking observations, as there is no landing-place. Jan. 17th.-As usual, marshes, mosquitoes, windings, dead flats, and light winds; the mosquitoes in the cabin give no rest even during the day. Stream about two miles per hour. Course S.E.; the river averaging about one hundred and ten yards in width of clear water. Jan. 18th.-Country as usual, but the wind brisker. In company with Koorshid Aga's boats. I have bound the stock of Oswell's old gun with rhinoceros hide. All guns made for sport in wild countries and rough riding, should have steel instead of iron from the breech-socket, extending far back to within six inches of the shoulder-plate; the trigger-guard should likewise be steel, and should be carried back to an equal distance with the above rib; the steel should be of extra thickness, and screwed through to the upper piece; thus the two, being connected by screws above and below, no fall could break the stock.
