I finally went to headquarters--to the White Caps--where I would have gone in the first place if I had been acquainted. But even at headquarters I found difficulties; I perceived that there were things about the White Cap Corps which one member knew and another one didn't. It was natural; for very few members of any organization know ALL that can be known about it. I doubt there is a man or a woman in Heidelberg who would not answer promptly and confidently three out of every five questions about the White Cap Corps which a stranger might ask; yet it is a very safe bet that two of the three answers would be incorrect every time. There is one German custom which is universal--the bowing courteously to strangers when sitting down at table or rising up from it. This bow startles a stranger out of his self-possession, the first time it occurs, and he is likely to fall over a chair or something, in his embarrassment, but it pleases him, nevertheless. One soon learns to expect this bow and be on the lookout and ready to return it; but to learn to lead off and make the initial bow one's self is a difficult matter for a diffident man. One thinks, "If I rise to go, and tender my bow, and these ladies and gentlemen take it into their heads to ignore the custom of their nation, and not return it, how shall I feel, in case I survive to feel anything." Therefore he is afraid to venture. He sits out the dinner, and makes the strangers rise first and originate the bowing. A table d'hôte dinner is a tedious affair for a man who seldom touches anything after the three first courses; therefore I used to do some pretty dreary waiting because of my fears. It took me months to assure myself that those fears were groundless, but I did assure myself at last by experimenting diligently through my agent. I made Harris get up and bow and leave; invariably his bow was returned, then I got up and bowed myself and retired. Thus my education proceeded easily and comfortably for me, but not for Harris. Three courses of a table d'hôte dinner were enough for me, but Harris preferred thirteen. Even after I had acquired full confidence, and no longer needed the agent's help, I sometimes encountered difficulties. Once at Baden-Baden I nearly lost a train because I could not be sure that three young ladies opposite me at table were Germans, since I had not heard them speak; they might be American, they might be English, it was not safe to venture a bow; but just as I had got that far with my thought, one of them began a German remark, to my great relief and gratitude; and before she got out her third word, our bows had been delivered and graciously returned, and we were off.
