There is an old custom, almost dead now. It is only in hidden and unfrequented spots that it still survives – I mean ‘the wading of the sun.’ It was common enough thirty years ago. The modus operandi was as follows :- As the sun rose on Easter morn, a bucket of water was placed in such a position that the sun was reflected in it. If the sun waded, i.e. glimmered in the water, it would rain that day; but if it kept fine in the morning and rained in the afternoon, then the spring would be fine and the autumn wet, and vice versa. On this morning too the flight of crows was carefully observed; if they settled near home, instead of flying far afield to feed, the farmer shook his head, for they plainly told him, by doing so, that grub and other pests would sorely afflict his crops that year.
