At length, when the time arrived for Peter to set out on his return to his own dominions, the King of England made him a present of a beautiful yacht, which had been built for his own use in his voyages between England and Holland. The name of the yacht was the Royal Transport. It was an armed vessel, carrying twenty-four guns, and was well-built, and richly finished and furnished in every respect. The Czar set sail from England in this yacht, taking with him the companions that he had brought with him into England, and also a considerable number of the persons whom he had engaged to enter into his service in Russia. Some of these persons were to be employed in the building of ships, and others in the construction of a canal to connect the River Don with the River Wolga. The Don flows into the Black and the Wolga into the Caspian Sea, and the object of the canal was to allow Peter's vessels to pass from one sea into the other at pleasure. As soon as the canal should be opened, ships could be built on either river for use in either sea. The persons who had been engaged for these various purposes were promised, of course, very large rewards to induce them to leave their country. Many of them afterward had occasion bitterly to regret their having entered the service of such a master. They complained that, after their arrival in Russia, Peter treated them in a very unjust and arbitrary manner. They were held as prisoners more than as salaried workmen, being very closely watched and guarded to prevent their making their escape and going back to their own country before finishing what Peter wished them to do. Then, a large portion of their pay was kept back, on the plea that it was necessary for the emperor to have security in his own hands for their fidelity in the performance of their work, and for their remaining at their posts until their work was done. There was one gentleman in particular, a Scotch mathematician and engineer, who had been educated at the University of Aberdeen, that complained of the treatment which he received in a full and formal protest, which he addressed to Peter in writing, and which is still on record. He makes out a very strong case in respect to the injustice with which he was treated. But, however disappointed these gentlemen may have been in the end, they left England in the emperor's beautiful yacht, much elated with the honor they had received in being selected by such a potentate for the execution of important trusts in a distant land, and with high anticipations of the fame and fortune which they expected to acquire before the time should arrive for them to return to their own country. From England the yacht sailed to Holland, where Peter disembarked, in order to join the embassy and accompany them in their visits to some other courts in Central Europe before returning home.
