J. M. Barrie,
The Little White Bird — Chapter 18…
(1902)
“ Though Peter still remembers Maimie he is become as gay as ever, and often in sheer happiness he jumps off his goat and lies kicking merrily on the grass. Oh, he has a joyful time! But he has still a vague memory that he was a human once, and it makes him especially kind to the house-swallows when they revisit the island, for house-swallows are the spirits of little children who have died. They always build in the eaves of the houses where they lived when they were humans, and sometimes they try to fly in at a nursery window, and perhaps that is why Peter loves them best of all the birds. ”
