The Waves, by Virginia Woolf
(Auto-generated)

In the garden the birds that had sung erratically and spasmodically in the dawn on that tree, on that bush, now sang together in chorus, shrill and sharp; now together, as if conscious of companionship, now alone as if to the pale blue sky.†
*

erratically = in a manner that is irregular or unpredictable
Then another cloud was caught in the light and another and another, so that the waves beneath were arrow-struck with fiery feathered darts that shot erratically across the quivering blue.†
The windows showed erratically spots of burning fire, the elbow of one branch, and then some tranquil space of pure clarity.†
Erratically rays of light flashed and wandered, like signals from sunken islands, or darts shot through laurel groves by shameless, laughing boys.†
