NOTE 2.—Marco exaggerates a little about the bamboos; but before gunpowder became familiar, no sharp explosive sounds of this kind were known to ordinary experience, and exaggeration was natural. I have been close to a bamboo jungle on fire. There was a great deal of noise comparable to musketry; but the bamboos were not of the large kind here spoken of. The Hon. Robert Lindsay, describing his elephant-catching in Silhet, says: “At night each man lights a fire at his post, and furnishes himself with a dozen joints of the large bamboo, one of which he occasionally throws into the fire, and the air it contains being rarefied by the heat, it explodes with a report as loud as a musket.” (_Lives of the Lindsays_, III. 191.) [Dr. Bretschneider (_Hist. of Bot. Disc._ I. p. 3) says: “In corroboration of Polo’s statement regarding the explosions produced when burning bamboos, I may adduce Sir Joseph Hooker’s Himalayan Journals (edition of 1891, p. 100), where in speaking of the fires in the jungles, he says: ‘Their triumph is in reaching a great bamboo clump, when the noise of the flames drowns that of the torrents, and as the great stem-joints burst, from the expansion of the confined air, the report is as that of a salvo from a park of artillery.’”—H. C.] [Illustration: Mountaineers on the Borders of Sze ch’wan and Yun-nan.] Richthofen remarks that nowhere in China does the bamboo attain such a size as in this region. Bamboos of three palms in girth (28 to 30 inches) exist, but are not ordinary, I should suppose, even in Sze-ch’wan. In 1855 I took some pains to procure in Pegu a specimen of the largest attainable bamboo. It was 10 inches in diameter. NOTE 3.—M. Gabriel Durand, a missionary priest, thus describes his journey in 1861 to Kiangka, _viâ_ Ta-t’sien-lu, a line of country partly coincident with that which Polo is traversing: “Every day we made a journey of nine or ten leagues, and halted for the night in a _Kung-kuan_. These are posts dotted at intervals of about ten leagues along the road to Hlassa, and usually guarded by three soldiers, though the more important posts have twenty. With the exception of some Tibetan houses, few and far between, these are the only habitations to be seen on this silent and deserted road.... Lytang was the first collection of houses that we had seen in ten days’ march.” (_Ann. de la Propag. de la Foi_, XXXV. 352 _seqq._)
