Our first excursion was to Neckarsteinach, two and a half leagues from here. The road follows the Neckar, and at certain places rises boldly above the river, which flows between two hills, broken by rocks of the color of red chalk, which often jut out from either side. Farther on the valley widens, and a pretty rising ground, crowned by ruins, suddenly presents itself in the midst of a wide plain, where sheep are feeding. Neckarsteinach itself is only a little village, containing, however, three castles, two of which are in ruins. The third is still inhabited, and commands a magnificent view. In the evening we returned to Heidelberg by moonlight. Another day we started for what is here called "The Mountain," though it is at most no higher than Le Suchet. As the needful supplies are not to be obtained there, we took our provisions with us. We had so much fun out of this, that I must tell you all about it. In the morning Z--bought at the market veal, liver, and bacon enough to serve for three persons during two days. To these supplies we added salt, pepper, butter, onions, bread, and some jugs of beer. One of us took two saucepans for cooking, and some alcohol. Arrived at the summit of our mountain, we looked out for a convenient spot, and there we cooked our dinner. It did not take long, nor can I say whether all was done according to the rules of art. But this I know,--that never did a meal seem to me better. We wandered over the mountain for the rest of the day, and at evening came to a house where we prepared our supper after the same fashion, to the great astonishment of the assembled household, and especially of an old woman who regretted the death of her husband, because she said it would certainly have amused him. We slept on the ground on some straw, and returned to Heidelberg the next day in time for dinner. The following day we went to Mannheim to visit the theatre. It is very handsome and well appointed, and we were fortunate in happening upon an excellent opera. Beyond this, I saw nothing of Mannheim except the house of Kotzebue and the place where Sand was beheaded. To-day I have made my visits to the professors. For three among them I had letters from Professors Schinz and Hirzel. I was received by all in the kindest way. Professor Tiedemann, the Chancellor, is a man about the age of papa and young for his years. He is so well-known that I need not undertake his panegyric here. As soon as I told him that I brought a letter from Zurich, he showed me the greatest politeness, offered me books from his library; in one word, said he would be for me here what Professor Schinz, with whom he had formerly studied, had been for me in Zurich. After the opening of the term, when I know these gentlemen better, I will tell you more about them. I have still to describe my home, chamber, garden, people of the house, etc. The next letter fills in this frame-work. TO HIS FATHER. HEIDELBERG, May 24, 1826.
