“Why,” said Polly, “how could I! I don't see—but I've forgotten to write to mamsie to-day; it's Wednesday, you know, and there's Monsieur coming.” And poor Polly looked out in despair to see the lively little music teacher advancing towards the house at an alarming rate of speed.

“That is because you were helping Van so long last evening over his lessons,” said Mrs. Whitney; “I am so sorry.”

“Oh, no,” cried Polly honestly, “I had plenty of time—but I forgot 'twas mamsie's day. What will she do!”

“You will have to let it go now till the afternoon, dear; there's no other way; it can go in the early morning mail.”

“Oh, dear,” sighed Polly, “I suppose I must.” And she went down to meet Monsieur with a very distressed little heart.

Phronsie laid down the note of invitation she was scribbling, and stopped to think; and a moment or two after, at a summons from a caller, Mrs. Whitney left the room.

“I know I ought to,” said Phronsie to herself and the dolls, “yes, I know I had; mamsie will feel, oh! so bad, when she don't get Polly's letter; and I know the way, I do, truly.”

She got up and went to the window, where she thought a minute; and then, coming back, she took up her little stubby pencil, and bending over a small bit of paper, she commenced to trace with laborious efforts and much hard breathing, some very queer hieroglyphics that to her seemed to be admirable, as at last she held them up with great satisfaction.

“Good-bye,” she said then, getting up and bowing to the dolls who sat among the interrupted invitations, “I won't be gone but a little bit of one minute,” and she went out determinedly and shut the door.

Nobody saw the little figure going down the carriage drive, so of course nobody could stop her. When Phronsie got to the gateway she looked up and down the street carefully, either way.
