You know, of course, that Europe has four landlocked seas, the Baltic, the Mediterranean, the Black and Caspian Seas. The Baltic is enclosed all round by European coasts; the Black and Caspian Seas belong to both Europe and Asia; while the Mediterranean lies between the three continents of the Old World—Europe, Asia, and Africa. Now the Baltic, Black, and Caspian Seas are of about the same size, each having an area about three times that of England and Wales. The Baltic is connected with the Atlantic by several sounds between the Danish islands and Scania. The Black Sea has only one outlet, the Bosporus. The Caspian Sea has no outlet at all, and is really a lake.

The Baltic is very shallow, its maximum depth, south-east of the Landsort lighthouse, being 250 fathoms. Next comes the Caspian Sea with a depth of 600 fathoms. The singular feature of this, the largest lake in the world, is that its surface lies 85 feet below that of the Black Sea. This last is the deepest of the three, for in it a sounding of 1230 fathoms has been taken.

All three seas are salt, the Baltic least and the Caspian most. Four great rivers enter the Black Sea, the Danube, Dniester, Dnieper, and Don. It therefore receives large volumes of fresh water. But along the bottom of the Bosporus an undercurrent of salt water passes into the Black Sea, which is compensated for by a surface stream of less salt and therefore lighter water flowing to the Mediterranean.

The Black Sea is not blacker than any other sea, nor is the White Sea white, the Yellow Sea yellow, or the Red Sea red. And so no faith should be accorded to the story of a captain in the Mediterranean who wished to sail to the Red Sea but went to the Black Sea—because he was colour-blind!

But now we can continue our heaving course, still accompanied by dolphins and porpoises. We look in at the harbour of Sebastopol, we anchor in open roadsteads off Caucasian towns, we moor our cables to the rings on the quay of Batum, and finally drop our anchor for the last time at a short distance from the coast of Asia Minor.

Proud and bright, with forest-clad heights in the background, Trebizond bathes in the rays of the midday sun. Small rowing-boats come out from the land to take passengers and goods to the quay. The Turkish boatmen scream all together, but no one listens to them. Every one is glad to be landed safe and sound with his baggage.

Trebizond to Teheran

Trebizond was a Greek colony seven hundred years before the birth of Christ, and from time immemorial Persian trade has made its way to the Black Sea by the road which still runs through Tabriz to Teheran, a distance of 800 miles. This traffic is now on the decline, for modern means of communication have taken the place of the old caravans, and most of their trade has been diverted to the Suez Canal and the Caucasian railways. Many large caravans, however, still journey to and fro along this road, which is so well made that one can drive not only to Tabriz, but still further to Teheran. It may, indeed, be softened by autumn rains or frozen hard on the high plateaus of Turkish Armenia, and the speed is not great when the same horses have to be used for distances of 160 miles.

It was a lively cavalcade that pounded and rattled over the Turkish and Persian roads in November, 1905. I was by no means alone. The Governors of Trebizond and Erzerum were so good as to provide me with an escort of six armed troopers on sturdy horses. In front rides a Turkish soldier on a piebald horse, carrying his carbine in a sling over his back, his sabre and dagger hanging at his side, and wearing a red fez with a white pagri[5] wound round it as a protection from sun and wind. Then I come in my carriage, drawn by three horses. Old Shakir, the coachman, is already my friend; it is he who prepares my meals and looks after me generally. I am well wrapped up in a Caucasian cloak, with a bashlik[6] over my cap, and lean back comfortably and look at the country as we drive along. Behind the carriage ride two soldiers on brown horses, engaged in a lively conversation and wondering whether they will be well tipped. Then come two clumsy carts, on which all my baggage is firmly secured. They have their own drivers and men, and are escorted by three troopers.

In this manner I travelled from Trebizond to Teheran. To the ceaseless rattle of the wheels and the heavy tramp of the horses' hoofs, I plunged day by day deeper into Asia. Soon the blue expanse of the Black Sea passed out of sight, as the road with many steep and sudden bends wound up to the top of a pass. On the other side it descended with as many windings to the bottom of a valley. And thus we went up and down till we were up at length on the level Armenian tableland.
