He remained at Rapallo until the birthday had passed, but his address had meantime become widely known, and the miniature postal arrangements at Rapallo were severely taxed. Letters, telegrams, flowers, and other gifts—mostly spontaneous expressions of gratitude from “unknown readers of the _Riddle of the Universe_“—reminded him of the larger world that now appreciated him. A still larger number of letters and gifts reached Jena from all parts of the world. Hundreds of German journals and periodicals devoted long and generous articles to the distinguished worker, and little festive commemorations were held at many of the universities. At Zurich, Professor Conrad Keller and Professor Arnold Lang delivered speeches which have since been published. Jena sent a deputation consisting of a number of its professors to visit the hero in person at Rapallo. Reflecting on these remarkable demonstrations and the extraordinary correspondence that continually reaches Haeckel, one is disposed to repeat of him the phrase applied to a great heretical teacher of the Middle Ages, Peter Abélard: “Never was man so loved—and so hated.” A feature of the commemoration that peculiarly gratified him was the special festive number of the German students’ lively periodical, _Jugend_, published at Munich. On February 16th it appeared as a “Haeckel number,” full of sprightly anecdote and generous appreciation, and bearing on its cover a striking reproduction in colour of the Lenbach portrait. His letter of thanks to the journal shows that the repose and the beauty of Italy, and the outburst of affection his birthday has provoked, have set him perfectly atune to life once more. “Ah! Prithee stay, thou art so fair,” he almost says in the Goethe phrase, as he “hails the moment fleeing.” He goes on to deprecate the effort to make “a learned man” of him. “That, alas, I am not. We have in Germany many professors and teachers who are more learned, and have read far more books than your poor Jena schoolmaster. But from my earliest youth, since I tore up flowers and admired butterflies in my fourth year, I have yielded to the inclination of my heart and studied incessantly one great book—Nature. This greatest of all books has taught me to know the true God, the God of Spinoza and Goethe. Then as physician I saw human life in all its heights and depths, and in my many travels through half the globe I learned the inexhaustible splendour of the earth. And I have honestly tried with all my modest powers, to reproduce with pen and pencil a part of what I saw, and reveal it to my fellows. I have had to fight many a hard fight, and in my hatred of lies and hypocrisy and decaying traditions I have at times struck a sharp note. But I trust, dear _Youth_, that thou wilt not judge all that harshly in so old and storm-tried, a warrior, and that thou wilt go on to stand with me, shoulder to shoulder, fighting for the spiritual
