Official passports are curious documents, consisting of long narrow strips of palm-leaf coiled into a ring, and at each end is an embossed stamp. This stamp determines the real weight of the document, and is the first point examined before reading the order. These leaves are almost imperishable, being tough and entirely unaffected by water, and for such a purpose are superior to paper. When the writing grows indistinct it is easily made legible by wetting the finger and rubbing it over the leaf, thus cleansing the smooth surface and filling the scratches with a thin film of dirt. Such a passport frequently includes an order to inferior officials to furnish the traveler with the necessary elephants for his journey. Throughout Laos written official documents are almost invariably thus scratched with a style on a strip of palm-leaf. The enormous number of wild elephants in the forests and domesticated elephants in the towns strikes one with amazement. Tigers, deer, wild hogs, pea-fowls and jungle-chickens also abound in the forests; while dogs, cats, crows and lizards are among the domesticated pets. The country is rich, not only in valuable timber, but in minerals. The opening up of the market by railroad would result in immediate profit, bringing down the Laos products and taking back in exchange English and American manufactures, for which a large and increasing demand would be readily created. LAOS OIL AND WINE. Cocoa and betel-nut trees abound in Cheung Mai. Oil is made from the former, and the latter produces an article of commerce.
