In order to be of more direct service to observers of games of this character, let me give a short account of an observation of the kind made some time ago--one of the simplest of many actual situations which my two little girls, Helen and Elizabeth, have acted out together. It is a very commonplace case, a game the elements of which are evident in their origin; but I choose this rather than one more complex, since observers are usually not psychologists, and they find the elementary the more instructive. On May 2 I was sitting on the porch alone with the children--the two mentioned above, aged respectively four and a half and two and a half years. Helen, the elder, told Elizabeth that she was her little baby; that is, Helen became "mamma," and Elizabeth the "baby." The younger responded by calling her sister "mamma," and the play began. "You have been asleep, baby. Now it is time to get up," said mamma. Baby rose from the floor--first falling down in order to rise!--was seized upon by "mamma," taken to the railing to an imaginary washstand, and her face washed by rubbing. Her articles of clothing were then named in imagination, and put on, one by one, in the most detailed and interesting fashion. During all this "mamma" kept up a stream of baby talk to her infant: "Now your stockings, my darling; now your skirt, sweetness--O! no--not yet--your shoes first," etc., etc. Baby acceded to all the details with more than the docility which real infants usually show. When this was done--"Now we must go tell papa good-morning, dearie," said mamma. "Yes, mamma," came the reply; and hand in hand they started to find papa. I, the spectator, carefully read my newspaper, thinking, however, that the reality of papa, seeing that he was so much in evidence, would break in upon the imagined situation. But not so. Mamma led her baby directly past me to the end of the piazza, to a column in the corner. "There's papa," said mamma; "now tell him good-morning."--"Good-morning, papa; I am very well," said baby, bowing low to the column. "That's good," said mamma, in a _gruff, low voice_, which caused in the real papa a thrill of amused self-consciousness most difficult to contain. "Now you must have your breakfast," said mamma. The seat of a chair was made a breakfast table, the baby's feigned bib put on, and her porridge carefully administered, with all the manner of the nurse who usually directs their breakfast. "Now" (after the meal, which suddenly became dinner instead of breakfast), "you must take your nap," said mamma. "No, mamma; I don't want to," said baby. "But you must."--"No; you be baby, and take the nap."--"But all the other children have gone to sleep, dearest, _and the doctor says you must_," said mamma. This convinced baby, and she lay down on the floor. "But I haven't undressed you." So then came all the detail of undressing; and mamma carefully covered her up on the floor with a light shawl, saying: "Spring is coming now; that'll be enough.
