Though not so large as formerly, these timber rafts are still sometimes 400 or 500 ft.
The rafts used are the so-called kelleks, of wood supported on inflated skins, which are broken up at Bagdad, the wood sold and the skins carried back by caravan.
From Jalalabad downwards the river is navigable by boats or rafts of inflated skins, and is considerably used for purposes of commerce.
It is a rapid river of considerable volume, and below Erzingan is navigable, down stream, for rafts.
Taking a northerly course, it quits the mountains at Immenstadt, and, flowing by Kempten, from which point it is navigable for rafts, forms for some distance the boundary between Bavaria and Wurttemberg, and eventually strikes the Danube (right bank) just above Ulm.
