and electricity, the printing-press, newspapers, and all the other inventions that were products of Europe and America. In exchange, the art-loving people of Japan gave their visitors beautiful works in bronze, lacquer, porcelain, bamboo, ivory, silk, and paper, and great swords, spears and shields, wonderfully inlaid and decorated, that were handed down from their feudal days. While the fleet stayed Japanese spy-boats kept watch in the bay, to see that their young men did not board the foreign ships in their desire to see something of the world. Time and again the young Yoshida Shoin and a friend tried to break through the blockade, but every time they were sent back to shore. At last the two left Yedo for the port of Shimoda. The Americans set up telegraph poles, and laid rails to show the working of the model locomotive. They gave an exhibition of the steam-engine. This caused great excitement in the country near Yedo, and every one who could went to see the strange performance. Already there was a struggle between those who were eager to learn the inventions of the Americans, and those who were afraid that the new ideas would spoil old Japan. Many an ambitious youth stared at the Mikado's presents, and tried to learn more of their secrets from the sailors on their way to or from the fleet. The treaty was signed on March 31, 1854, and agreed that shipwrecked sailors should be cared for, provisions needed by ships should be obtained in the ports, and American vessels allowed to anchor in the two harbors of Shimoda and Hakodate. Actual trade was not yet allowed, nor were Americans to be permitted to reside in Japan. The hermit nation was not at all eager to enter into competition with other countries, nor to allow foreigners to trade with her. Commodore Perry knew, however, that even the slight terms he had gained would prove the beginning of the opening up of Japan to the rest of the world. April 18, 1854, Perry left the bay of Yedo for Shimoda, and there the fleet stayed until early in May. While the squadron was there two Americans, who were botanizing on land, met the youth Yoshida Shoin and his friend. The young Japanese gave the Americans a letter, but seeing some native officers approaching, he and his friend stole away. A few nights later the watch on the war-ship _Mississippi_ heard voices calling, "Americans, Americans!" They found the two Japanese youths in a small boat, and took them on board. Paper and writing materials were found hidden in their clothes, and they explained that they wanted to go with the fleet to America, and write down what they saw there. The commodore, however, felt that he was in honor bound to send the two young men back to their homes; and did so. Yoshida later came to be one of the leaders of the new Japan that ended the long line of Shogun rulers, and made the Mikado the actual emperor.
