I take pride in Clara's remark, because it shows that although she was only three years old, her fireside teachings were already making her a thinker--a thinker and also an observer of proportions. I am not claiming any credit for this. I furnished to the children worldly knowledge and wisdom, but was not competent to go higher, and so I left their spiritual education in the hands of the mother. A result of this modesty of mine was made manifest to me in a very striking way, some years afterward, when Jean was nine years old. We had recently arrived in Berlin, at the time, and had begun housekeeping in a furnished apartment. One morning at breakfast a vast card arrived--an invitation. To be precise, it was a command from the Emperor of Germany to come to dinner. During several months I had encountered socially, on the Continent, men bearing lofty titles; and all this while Jean was becoming more and more impressed, and awed, and subdued, by these imposing events, for she had not been abroad before, and they were new to her--wonders out of dreamland turned into realities. The imperial card was passed from hand to hand, around the table, and examined with interest; when it reached Jean she exhibited excitement and emotion, but for a time was quite speechless; then she said, "Why, papa, if it keeps going on like this, pretty soon there won't be anybody left for you to get acquainted with but God." It was not complimentary to think I was not acquainted in that quarter, but she was young, and the young jump to conclusions without reflection. Necessarily, I did myself the honor to obey the command of the Emperor Wilhelm II. Prince Heinrich, and six or eight other guests were present. The Emperor did most of the talking, and he talked well, and in faultless English. In both of these conspicuousnesses I was gratified to recognize a resemblance to myself--a very exact resemblance; no, almost exact, but not quite that--a modified exactness, with the advantage in favor of the Emperor. My English, like his, is nearly faultless; like him I talk well; and when I have guests at dinner I prefer to do all the talking myself. It is the best way, and the pleasantest. Also the most profitable for the others. I was greatly pleased to perceive that his Majesty was familiar with my books, and that his attitude toward them was not uncomplimentary. In the course of his talk he said that my best and most valuable book was "Old Times on the Mississippi." I will refer to that remark again, presently.
