It was about this time that Zelter threw out the hint that he was going down to Weimar to see his friend Goethe--would Felix like to go? Felix would be delighted, and when the boy's father and mother were interviewed, they were pleased, too, at the prospect of their boy's making the acquaintance of the greatest poet of Germany. Felix was duly cautioned about how he should conduct himself. He promised, of course, and also agreed to write a letter home every day, recording the exact language that the author of "Werther" used in his presence. Goethe and the Carlylian Zelter had been cronies for many years. The poet delighted in the company of the gruff old stone-mason musician, and together they laughed at the world over their pipes and mugs. And sometimes, alas, they hotly argued and raised their voices in donner-und-blitzen style, as Germans have been known to do. Yet they were friends, and the honest Zelter's yearly visits were as a godsend to the old poet, who was often pestered to distraction by visitors who only voiced the conventional, the inconsequential and absurd. Here was a man who tried his steel. Now, Zelter had his theories about teaching harmony--theories too finely spun for any one but himself to grasp. Possibly he himself did not seize them very firmly, but only argued them in a vain attempt to clear the matter up in his own mind. The things we are not quite sure of are those upon which we insist. Goethe had pooh-poohed and smitten the table with his "stein" in denial. And now Zelter, the frank and bold, stealthily and by concocted plot and plan took his pupil, Felix Mendelssohn, with him on a visit to Weimar. He wanted to confound his antagonist and to reveal by actual proof the success that could be achieved where correct methods of instruction were followed. Jean Jacques had written a novel showing what right theories, properly followed up, could do for his hero. Zelter had done better--he exhibited the youth. "A girl in boy's clothes, I do believe," said Goethe, with his usual banter, in the evening when a little company had gathered in the parlors. Felix sat on his teacher's knee, with his arms around the old man's neck, girl-like. "Does he play?" continued Goethe, going over and opening the piano. "Oh, a little!" answered Zelter indifferently. The ladies insisted--they always had music when Zelter made them a visit. "Come, make some noise and awaken the spirits that have so long lain slumbering!" ordered the old poet. Zelter advanced to the piano and played a stiff, formal little tune of his own. He arose and motioned to Felix. "Play that!" said the teacher.
