A faint black rim was left behind them. The rocks which had been misty and soft hardened and were marked with red clefts. Sharp stripes of shadow lay on the grass, and the dew dancing on the tips of flowers and leaves made the garden like a mosaic of single sparks not yet formed into a whole."},

Let me sit here for ever with bare things, this coffee cup, this knife, this fork, things in themselves, myself being myself."},
