Her quickness of thought and readiness with an instant and convincing answer were typified one dusty, blustering day when we were out walking. A cloud of dust enveloped us, to her great indignation, and being a very vehement character she exclaimed, "I should like to kill the dust!" In answer to my reproof, "Do not be so foolish. How can anyone kill the dust?" she replied, "Very easily--pour a little water on it." This was at the age of 4 years. . . . She is highly imaginative, and lives largely in a dream world of her own creation. Her games are nearly all pretense that she is someone else, and that she is surrounded by companions, sometimes purely fictitious, though often characters out of books that have been read to her. . . . When being read to, she asks the meaning of every unfamiliar word, and rarely forgets it, using it thereafter in its proper place. . . . Many of her forebears have been distinguished men and women, and on both sides her family have been people of more than average capacity and cultivation. . . . From an early age she has shown unusual muscular coördination, using her fingers daintily and with precision. From her eighth month she used a paper and pencil, drawing recognizable figures. At 4 years she could illustrate a little story composed by herself. . . . The source of much of her knowledge is a mystery to her parents, and can only be explained by her keen observation and retentive memory, as well as by a power of comprehension much beyond her years. However absorbed she may appear to be in her play, talking vigorously to herself and to imaginary companions all the time, she nevertheless hears everything that is said in her presence, though months will often pass before she alludes to it. . . . She taught herself her letters from street signs and books, and could print them all before she was three, and during the next few months would write letters of several pages, of her own composition, having the words, of course, spelled for her. . . . She has an accurate ear and could sing a tune correctly before her second birthday, and dances in excellent time. . . . Every new thought or impression is at once associated with some previous idea. Hence, doubtless, her marvelous memory. For example, in a country walk she noticed a typical Virginia snake fence, having never seen one before. After a single moment's hesitation she said, "You see that M or W fence?" . . . At the age of five years she had coined twenty-three words-- e.g., _laten_, to make late; _neaten_, to make neat; _plak_, to pretend; _up-jar_, pitcher.
