Among the lessons which the avenging powers have given me is one which I dare not forget, that is, the command not to search into hidden things, because they are to remain hidden. For instance, in my excursions in Schonen, I had noticed a kind of stones found in scattered places of peculiar and very characteristic shapes. They represented either types of living creatures, such as birds, or hats and helmets. There were also others with furrows which resembled the tracings on meteoric stones. Without being clear as to their origin, I received the impression that they were not a mere freak of nature. Their form showed that they were works of art, produced and elaborated by human hands. For two years I continued to look for them, and after I had interested a friend of mine who lived at a distance in the matter, I told him where some could be found, that he might send me a photograph of them. But the expedition failed, and a year later I discovered that I had given him a wrong address. Ever since then, when I have obstinately set about such investigations, hindrances have arisen in such an extraordinary way that I could not attribute them to chance. Thus, for instance, I had resolved one morning to make an expedition with an antiquarian in order to solve the question once for all. In the street before my door a nail came loose in my boot and stuck in my foot. At first I took no notice of it, but as I approached my friend's door the pain became so great that I had to stand still. It was impossible to proceed, or to turn back. In great annoyance I drew off my boot and flattened the nail with my knife. A vague remembrance of a passage I had read in Swedenborg came to me simultaneously-- "When the avenging spirits see an evil act, or the intention to commit a wrong, they punish by inflicting pain in the foot, the hand, or the neighbourhood of the diaphragm." But I was so spurred on by the thirst for knowledge, which I regarded as lawful and praiseworthy, that I resumed my interrupted attempt, and soon joined my companion. We intended first to investigate a grotto in the park. But the entrance was blocked up with heaps of abominable filth piled up in such a challenging or rather ironical way as to make me smile. The other place, well known to me, where these stones are to be found, is in a garden, where great blocks of them are grouped round a tree, and they are easily got at. But this morning the gardener has fenced off the tree and the antiquities with a row of flower-pots, so that I cannot get there to show my learned companion anything. A pretty fiasco! Irritated by all these hindrances, I take my friend, who begins to look sceptical, right through the town to a courtyard where a whole museum of these curiosities has been collected. There the matter will be settled once for all, and I expect to see him startled. On our arrival we are greeted by the barking of a vile cur; as we endeavour to drive
