at discharges itself into the Euxine Sea。 There is no doubt but it was by the nations inhabiting these several countries that the great empires of the Assyrians； Medes； and Persians had communication with the most distant parts of the east and west。
An entire stop is now put to this communication。 All these countries have been laid waste by the Tartars；＇12＇ and are still infested by this destructive nation。 The Oxus no longer runs into the Caspian Sea； the Tartars； for some private reasons； have changed its course； and it now loses itself in the barren sands。＇13＇
The Jaxartes； which was formerly a barrier between the polite and barbarous nations； has had its course turned in the same manner by the Tartars； and it no longer empties itself into the sea。＇14＇
Seleucus Nicator formed the project of joining the Euxine to the Caspian Sea。＇15＇ This project； which would have greatly facilitated the commerce of those days； vanished at his death。＇16＇ We are not certain it could have been executed in the isthmus which separates the two seas。 This country is at present very little known； it is depopulated； and full of forests； however； water is not wanting； for an infinite number of rivers roll into it from Mount Caucasus； but as this mountain forms the north of the isthmus； and extends like two arms＇17＇ towards the south； it would have been a grand obstacle to such an enterprise； especially in those times； when they had not the art of making sluices。
It may be imagined that Seleucus would have joined the two seas in the very place where Peter I has since joined them； that is； in that neck of land where the Tanais approaches the Volga； but the north of the Caspian Sea was not then discovered。
While the empires of Asia enjoyed the commerce of luxury； the Tyrians had the commerce of economy； which they extended throughout the world。 Bochard has employed the first book of his Canaan in enumerating all the colonies which they sent into all the countries bordering upon the sea； they passed the pillars of Hercules； and made establishments on the coasts of the ocean。＇18＇
In those times their pilots were obliged to follow the coasts； which were； if I may so express myself； their compass。 Voyages were long and painful。 The laborious voyage of Ulysses has been the fruitful subject of the finest poem in the world； next to that which alone has the preference。
The little knowledge which the greatest part of the world had of those who were far distant from them favoured the nations engaged in the economical commerce。 They managed trade with as much obscurity as they pleased； they had all the advantages which the most intelligent nations could take over the most ignorant。
The Egyptians a people who by their religion and their manners were averse to all communication with strangers had scarcely at that time any foreign trade。 They enjoyed a fruitful soil and great plenty。 Their country was the Japan of those times； it possessed everything within itself。
So little jealous were these people of commerce； that they left that of the Red Sea to all the petty nations that had any harbours in it。 Here they suffered the Idumeans； the Syrians and the Jews to have fleets。 Solomon employed in this navigation the Tyrians； who knew those seas。＇19＇
Josephus＇20＇ says that this nation； being entirely employed in agriculture； knew little of navigation： the Jews； therefore； traded only occasionally in the Red Sea。 They took from the Idumeans Eloth and Eziongeber； from whom they received this commerce； they lost these two cities； and with them lost this commerce。
It was not so with the Phoenicians： theirs was not a commerce of luxury； nor was their trade owing to conquest； their frugality； their abilities； their industry； their perils； and the hardships they suffered； rendered them necessary to all the nations of the world。
Before Alexander； the people bordering on the Red Sea traded only in this sea； and in that of Africa。 The astonishment which filled the globe at the discovery of the Indian Sea； under that conqueror； is a sufficient proof of this。 I have observed＇21＇ that bullion was always carried to the Indies； and never any brought thence； now the Jewish fleets； which brought gold and silver by the way of the Red Sea； returned from Africa； and not from the Indies。＇22＇
Besides； this navigation was made on the eastern coast of Africa； for the state of navigation at that time is a convincing proof that they did not sail to a very distant shore。
I am not ignorant that the fleets of Solomon and Jehoshaphat returned only every three years； but I do not see that the time taken up in the voyage is any proof of the greatness of the distance。
Pliny and Strabo inform us that the junks of India and the Red Sea were twenty days in performing a voyage which a Greek or Roman vessel would accomplish in seven。＇23＇ In this proportion； a voyage of one year； made by the fleets of Greece or Rome； would take very nearly three when performed by those of Solomon。 Two ships of unequal swiftness do not perform their voyage in a time proportionate to their swiftness。 Slowness is frequently the cause of much greater slowness。 When it becomes necessary to follow the coast； and to be incessantly in a different position； when they must wait for a fair wind to get out of a gulf； and for another to proceed； a good sailor takes the advantage of every favourable moment； while the other still continues in a difficult situation； and waits many days for another change。
The slowness of the Indian vessels； which in an equal time could make but the third of the way of those of the Greeks and Romans； may be explained by what we every day see in our modern navigation。 The Indian vessels； which were built with a kind of sea…rushes； drew less water than those of Greece and Rome； which were of wood and joined with iron。
We may compare these Indian vessels to those at present made use of in ports of little depth of water。 Such are those of Venice； and even of all Italy in general。＇24＇ of the Baltic； and of the province of Holland。＇25＇ Their ships； which ought to be able to go in and out of port； are built round and broad at the bottom； while those of other nations； who have good harbours； are formed to sink deep into the water。 This mechanism renders these last…mentioned vessels able to sail much nearer the wind； while the first can hardly sail； except the wind be nearly in the poop。 A ship that sinks deep into the water sails towards the same side with almost every wind； this proceeds from the resistance which the vessel； while driven by the wind； meets with from the water； from which it receives a strong support； and from the length of the vessel which presents its side to the wind； while； from the form of the helm； the prow is turned to the point proposed； so that she can sail very near the wind； or； in other words； very near the point whence the wind blows。 But when the hull is round and broad at the bottom； and consequently draws little water； it no longer finds this steady support； the wind drives the vessel； which is incapable of resistance； and can run them but with a small variation from the point opposite to the wind。 Whence it follows that broad…bottomed v
