A plant growing in the dense jungles of Langsuam, Siam, was described by H. Warington Smyth, in an address to the Royal Geographical Society, as having the property of setting up a great irritation in the skin of any person coming in contact with it. "It has a large, broad leaf, and the Siamese declare that, after being badly stung by it, the only remedy is the heat of a fire; to bathe in a stream, which is the natural impulse, is considered absolutely fatal. A spot on the Kra-Champawn trail is known as _Burmatai_, from the fact that a party of Burmese, coming across to harry their neighbors in the old fighting days, are said to have got into a thick growth of this plant, and to have bathed in the stream to allay the agony, with the result that they all died there." The Siamese call the plant _kalang-ton chang_. In the western part of Belgium the dog has been employed as a beast of burden from time immemorial. The Belgian dog (known only by this name) is a large, compactly built animal, measuring from twenty to thirty inches in height; the hair is smooth and short, generally tan or dark brown in color. It is the custom to crop both ears and tail. The dogs are usually driven before carts weighing from one hundred to one hundred and twenty pounds, in teams of from two to six abreast. A harness very similar in arrangement to that of the horse is used. Six of these animals will draw from six to eight hundred pounds. They are put to work when about a year old. They vary in price from twenty-five to sixty shillings. There are over two thousand dogs in Ghent licensed as draught animals. A plant described by M. Henri Chantrey as most probably answering to the manna found by the Hebrews in the desert is the thallophyte _Canona esculenta_, or edible lichen, which grows in the deserts of Persia, Arabia, Mesopotamia, and Sahara. It is a grayish cryptogam of about the size of a pea, bearing short bracteate appendages on its top; when cut, it resembles a mass of dull white flour paste. It is an ephemeral substance, and must be collected the morning it appears, as it will soon dry up; but when properly prepared it can be kept in a close vessel. It is highly appreciated by the wandering Arabs, who have often been saved by it from starvation, and they lay up stores of it when opportunity offers. It is easily collected, for it never adheres to any foreign body, and, so far as appearance goes, seems as if it might have been thrown on the ground. There is but little suggestion of the mushroom in its taste, which is rather starchy, with a slight flavor of sugar. Cattle are very fond of it. The Arabs boil it into a gelatinous paste, which they serve in various ways. They preserve it by drying it in the shade and pack it in bladders or skins. It is not a complete first-class food, but is very good for a few days till something better can be got.
