The manner in which his attention was first turned to the subject of ship-building illustrated this. In those days Holland was the great centre of commerce and navigation for the whole world, and the art of ship-building had made more progress in that nation than in any other. The Dutch held colonies in every quarter of the globe. Their men-of-war and their fleets of merchantmen penetrated to every sea, and their naval commanders were universally renowned for their enterprise, their bravery, and their nautical skill. The Dutch not only built ships for themselves, but orders were sent to their ship-yards from all parts of the world, inasmuch as in these yards all sorts of vessels, whether for war, commerce, or pleasure, could be built better and cheaper than in any other place. One of the chief centres in which these ship and boat building operations were carried on was the town of Saardam. This town lies near Amsterdam, the great commercial capital of the country. It extends for a mile or two along the banks of a deep and still river, which furnish most complete and extensive facilities for the docks and ship-yards. Now it happened that, one day when Peter was with Le Fort at one of his country palaces where there was a little lake, and a canal connected with it, which had been made for pleasure-sailing on the grounds, his attention was attracted to the form and construction of a yacht which was lying there. This yacht having been sent for from Holland at the time when the palace grounds were laid out, the emperor fell into conversation with Le Fort in respect to it, and this led to the subject of ships and ship-building in general. Le Fort represented so strongly to his master the advantages which Holland and the other maritime powers of Europe derived from their ships of war, that Peter began immediately to feel a strong desire to possess a navy himself. There were, of course, great difficulties in the way. Russia was almost entirely an inland country. There were no good sea-ports, and Moscow, the capital, was situated very far in the interior. Then, besides, Peter not only had no ships, but there were no mechanics or artisans in Russia that knew how to build them.
