Notices of Kuniyah, Kaisariya, Sivas, Arzan-ar-Rumi, Arzangan, and Arjish, will be found in Polo’s contemporary Abulfeda. (See _Büsching_, IV. 303–311.) NOTE 3.—Paipurth, or Baiburt, on the high road between Trebizond and Erzrum, was, according to Neumann, an Armenian fortress in the first century, and, according to Ritter, the castle _Baiberdon_ was fortified by Justinian. It stands on a peninsular hill, encircled by the windings of the R. Charok. [According to Ramusio’s version Baiburt was the third relay from Trebizund to Tauris, and travellers on their way from one of these cities to the other passed under this stronghold.—H. C.] The Russians, in retiring from it in 1829, blew up the greater part of the defences. The nearest silver mines of which we find modern notice, are those of _Gumish-Khánah_ (“Silverhouse”), about 35 miles N.W. of Baiburt; they are more correctly mines of lead rich in silver, and were once largely worked. But the _Masálak-al-absár_ (14th century), besides these, speaks of two others in the same province, one of which was near _Bajert_. This Quatremère reasonably would read _Babert_ or Baiburt. (_Not. et Extraits_, XIII. i. 337; _Texier_, _Arménie_, I. 59.) NOTE 4.—Josephus alludes to the belief that Noah’s Ark still existed, and that pieces of the pitch were used as amulets. (_Ant._ I. 3. 6.) Ararat (16,953 feet) was ascended, first by Prof. Parrot, September 1829; by Spasski Aotonomoff, August 1834; by Behrens, 1835; by Abich, 1845; by Seymour in 1848; by Khodzko, Khanikoff, and others, for trigonometrical and other scientific purposes, in August 1850. It is characteristic of the account from which I take these notes (_Longrimoff_, in _Bull. Soc. Géog. Paris_, sér. IV. tom. i. p. 54), that whilst the writer’s countrymen, Spasski and Behrens, were “moved by a noble curiosity,” the Englishman is only admitted to have “gratified a tourist’s whim”! NOTE 5.—Though Mr. Khanikoff points out that springs of naphtha are abundant in the vicinity of Tiflis, the mention of _ship-loads_ (in Ramusio indeed altered, but probably by the Editor, to _camel-loads_), and the vast quantities spoken of, point to the naphtha-wells of the Baku Peninsula on the Caspian. Ricold speaks of their supplying the whole country as far as Baghdad, and Barbaro alludes to the practice of anointing camels with the oil. The quantity collected from the springs about Baku was in 1819 estimated at 241,000 _poods_ (nearly 4000 tons), the greater part of which went to Persia. (_Pereg. Quat._ p. 122; _Ramusio_, II. 109; _El. de Laprim._ 276; _V. du Chev. Gamba_, I. 298.) [The phenomenal rise in the production of the Baku oil-fields between 1890–1900, may be seen at a glance from the Official Statistics where the total output for 1900 is given as 601,000,000 poods, about 9,500,000 tons.
