The necessity for the completion of this work, and his desire to give his children every advantage of study, kept him longer in Europe than he had expected, and he writes to his brother Sidney on December 1, 1867: "I long to return, for age creeps on apace, and I wish to put my house in order for a longer and better journey to a better home." In the early part of February, 1868, he and his wife and daughter and youngest son left Dresden for Paris, stopping, however, a few days in Berlin. Mr. George Bancroft was our minister at the Prussian court, and he did all that courtesy could suggest to make the stay of his distinguished countryman a pleasant one. He urged him to stay longer, so that he might have the pleasure of presenting him at court, but this honor Morse felt obliged to decline. The inventor did, however, find time to visit the government telegraph office, of which Colonel (afterwards General) von Chauvin was the head, and here he received an ovation from all the operators, several hundred in number, who were seated at their instruments in what was then the largest operating-room in the world. Another incident of his visit to Berlin I shall give in the words of Mr. Prime:-- "Not to recount the many tributes of esteem and respect paid him by Dr. Siemens, and other gentlemen eminent in the specialty of telegraphy, one other unexpected compliment may be mentioned. The Professor was presented to the accomplished General Director of the Posts of the North German Bund, Privy Councillor von Phillipsborn, in whose department the telegraph had been comprised before Prussia became so great and the centre of a powerful confederation. "At the time of their visit the Director was so engaged, and that, too, in another part of the Post-Amt, that the porter said it was useless to trouble him with the cards. The names had not been long sent up, however, before the Director himself came hurriedly down the corridor into the antechamber, and, scarcely waiting for the hastiest of introductions, enthusiastically grasped both the Professor's hands in his own, asking whether he had 'the honor of speaking to Dr. Morse,' or, as he pronounced it 'Morzey.' "When, after a brief conversation, Mr. Morse rose to go, the Director said that he had just left a conference over a new post and telegraph treaty in negotiation between Belgium and the Bund, and that it would afford him great pleasure to be permitted to present his guest to the assembled gentlemen, including the Belgian Envoy and the Belgian Postmaster-General. There followed, accordingly, a formal presentation with an introductory address by the Director, who, in excellent English, thanked Mr. Morse in the name of Prussia and of all Germany for his great services, and speeches by the principal persons present--the Belgian envoy, Baron de Nothomb, very felicitously complimenting the Professor in French.
