We gave our preference to the last-named route.
We left Astrakhan at ten in the evening on board a heavy barge belonging to the Caucasus and Mercury steam-navigation company, towed by a tug down stream at the rate of five or six miles an hour.
We were all that afternoon and night, and part of the following day, descending the main channel of the Volga, and it was past noon before we reached the Nine Feet Station, for so they call the roadstead above which vessels of more than nine feet draught dare not venture.
All sight of land, of the seventy larger islands of the Delta, and even of the minor islets, and of the lowest sand-banks, had been lost for several hours, and we were here in the open sea, though scarcely beyond the boundary that the Creator has elsewhere fixed between land and water. For the Station which, if I can allow myself an apparent Irishism, is a moveable one, has to be pushed forward almost day by day as the sands of the Volga silt up far beyond the choked-up lands of the Delta, encroaching with a steady inroad on the depths of the waves; the Steppe everywhere widening as the sea dwindles, and suggesting the thought that the whole region that is now Steppe must in remote ages have been sea, and that whatever is now sea, must in time become Steppe.
Indeed, it seems not impossible to calculate how many years or centuries it may take for the sands of the Volga, aided by those of the Ural and the Emba on the eastern, and of the Kuma, the Terek, and the Kur or Kura, with its tributary the Aras, on the western shore, to fill up the land-locked Caspian, though its extreme depth, according to the Gazetteers, is 600 feet, and the area covered by it probably exceeds 180,000 square miles, a surface as large as that of Spain.
Kasan, once the residence of a redoubted horde, was probably, under Tartar sway, in a great measure a mere encampment, chiefly a city of tents; for whatever the guide-books may say, there is no positive evidence of its present buildings belonging to a date anterior to the Russian Conquest.
Its situation probably recommended itself to the Tartars chiefly on the score of strength; for although it stands high above the river, its present distance from it is at least three miles, and it is surrounded by a sandy and marshy plain, intersected by the channels of the Kasana river, erratic water-courses which may have proved sufficient obstacles to the onset of an invader, but which raise no less serious hindrances to the conveyance of goods from the landing-place to the town; an inconvenience hitherto not removed by the tramway, as it as yet only carries passengers.
Kasan is on the main line of communication between Central Russia and Siberia.
The travellers bound to that bourne embark here on steamers that go down the Volga as far as its confluence with the Kama, a tributary stream, and thence ascend the Kama, which is navigable all the way to Perm. From Perm a railway runs up to the Pass of the Ural mountains to Ekaterinenburg, probably to be in course of time continued to Tiumen, Tobolsk, Tomsk, Irkutsk, the Baikal Lake, the Chinese frontier at Kiakhta, the banks of the Amoor, and the shores of the Pacific Ocean.
Along this route it is calculated that some £3,000,000 worth of merchandise are brought yearly from Siberia down the Kama and up the Volga to the Nijni-Novgorod fair.
