But the aim and the end of our labours was to see one of our missives attract the notice of a passer-by, then excite his curiosity, and finally--if he opened it--rouse his unspeakable disgust and disappointment.
Like other tricksters, our game lasted long because of the ever-green credulity of our "public." In the ever-fresh stream of human life which daily flowed beneath our windows, there were sure to be one or more pedestrians who, with varying expressions of conscientious responsibility, unprincipled appropriation, or mere curiosity, would open our parcels, either to ascertain what trinket should be restored to its owner, or to keep what was to be got, or to see what there was to be seen.
One day when we dropped one of our parcels at the feet of a lady who was going by, she nonplussed us very effectually by ringing the bell and handing in to the footman "something which had been accidentally dropped from one of the upper windows." Fortunately for us the parcel did not reach Aunt Maria; Polly intercepted it.
As the passers-by never wearied of our parcels, I do not know when we should have got tired of our share of the fun, but for an occurrence which brought the amusement suddenly to an end.

One afternoon we had made up the neatest of little white-paper parcels, worthy of having come from a jeweller's, and I clambered on to the window-seat that I might drop it successfully (and quite clear of the area) into the street.

Just as I dropped it, there passed an elderly gentleman very precisely dressed, with a gold-headed cane, and a very well-brushed hat.

Pop! I let the cinder parcel fall on to his beaver, from which it rebounded to his feet.

The old gentleman looked quickly up, our eyes met, and I felt convinced that he saw that I had thrown it.
