Whilst we stood thus in silence for some time, divided into two hostile groups, the clouds above waxed ever redder and the evening seemed to grow more peaceful and mild; we could almost fancy we heard the regular breathing of nature as she put the final touches to her work of art--the glorious day we had just enjoyed; when, suddenly, the calm evening air was rent by a confused and boisterous cry of joy which seemed to come from the Rhine. A number of voices could be heard in the distance--they were those of our fellow-students who by that time must have taken to the Rhine in small boats. It occurred to us that we should be missed and that we should also miss something: almost simultaneously my friend and I raised our pistols: our shots were echoed back to us, and with their echo there came from the valley the sound of a well-known cry intended as a signal of identification. For our passion for shooting had brought us both repute and ill-repute in our club. At the same time we were conscious that our behaviour towards the silent philosophical couple had been exceptionally ungentlemanly; they had been quietly contemplating us for some time, and when we fired the shock made them draw close up to each other. We hurried up to them, and each in our turn cried out: "Forgive us. That was our last shot, and it was intended for our friends on the Rhine. They have understood us, do you hear? If you insist upon having that place among the trees, grant us at least the permission to recline there also. You will find a number of benches on the spot: we shall not disturb you; we shall sit quite still and shall not utter a word: but it is now past seven o'clock and we _must_ go there at once.
"That sounds more mysterious than it is," I added after a pause; "we have made a solemn vow to spend this coming hour on that ground, and there were reasons for the vow. The spot is sacred to us, owing to some pleasant associations, it must also inaugurate a good future for us. We shall therefore endeavour to leave you with no disagreeable recollections of our meeting--even though we have done much to perturb and frighten you."
The philosopher was silent; his companion, however, said: "Our promises and plans unfortunately compel us not only to remain, but also to spend the same hour on the spot you have selected. It is left for us to decide whether fate or perhaps a spirit has been responsible for this extraordinary coincidence."
