The next afternoon they set to work.

They established themselves in the middle of a great meadow, committing thereby an extreme act of trespass, and making their way to it over a ditch, a low wall, and through a blackberry hedge.

Here no prying eye would annoy them, their sole and most discreet spectator being Fido, and he was generally asleep.
Pilar had a drawing-block and used a pencil, Wilhelm sketched his picture on a page of a large album in colored chalks like a pastel.

She kept trying to peep at his work, but he would not allow it, and insisted on their making a compact not to look at one another's work of art till it was finished.

Two sittings sufficed, however, and the portraits could be exchanged.
