In several counties the custom of apple-howling (or Yuling), to which Herrick refers in his "Hesperides," is still in observance. A troop of boys go round the orchards in Sussex, Devonshire, and other parts, and forming a ring about the trees, they repeat these doggerel lines:
"Stand fast root, bear well top.
Pray God send us a good howling crop;
Every twig, apples big:
Every bough, apples enou;
Hats full, caps full,
Full quarters sacks full."
Hasted says: "There is an odd custom used in these parts, about Keston and Wickham, in Rogation Week; at which time a number of young men meet together for the purpose, and with a most hideous noise run into the orchards, and incircling each tree, pronounce these words:
"Stand fast root: bear well top,
God send us a youling sop,
Every twig apple big.
Every bough apple enow."
For which incantation the confused rabble expect a gratuity in money or drink, which is no less welcome: but if they are disappointed of both, they with great solemnity anathematize the owners and trees with altogether as significant a curse. "It seems highly probable that this custom has arisen from the ancient one of the perambulation among the heathens, when they made prayers to the gods for the use and blessing of the fruits coming up, with thanksgiving for those of the preceding year: and as the heathens supplicated Eolus, god of the winds, for his favourable blasts, so in this custom they still retain his name with a very small variation; this ceremony is called Youling, and the word is often used in their invocations.
