NOTE 1.—[Baber writes (_Travels_, p. 171) when arriving to the Lan-tsang kiang (Mekong River): “We were now on the border-line between Carajan and Zardandan: ‘When you have travelled five days you find a province called Zardandan,’ says Messer Marco, precisely the actual number of stages from Tali-fu to the present boundary of Yung-ch’ang. That this river must have been the demarcation between the two provinces is obvious; one glance into that deep rift, the only exit from which is by painful worked artificial zigzags which, under the most favourable conditions, cannot be called safe, will satisfy the most sceptical geographer. The exact statement of distance is a proof that Marco entered the territory of Yung-ch’ang.” Captain Gill says (II. p. 343–344) that the five marches of Marco Polo “would be very long ones. Our journey was eight days, but it might easily have been done in seven, as the first march to Hsia-Kuan was not worthy of the name. The Grosvenor expedition made eleven marches with one day’s halt—twelve days altogether, and Mr. Margary was nine or ten days on the journey. It is true that, by camping out every night, the marches might be longer; and, as Polo refers to the crackling of the bamboos in the fires, it is highly probable that he found no ‘_fine hostelries_’ on this route. This is the way the traders still travel in Tibet; they march until they are tired, or until they find a nice grassy spot; they then off saddles, turn their animals loose, light a fire under some adjacent tree, and halt for the night; thus the longest possible distance can be performed every day, and the five days from Ta-li to Yung-Ch’ang would not be by any means an impossibility.”—H.
