And on the same page you might read the following (for Ron's benefit who knows a certain problem with links):

the custom prevailing among the Roman Catholics of lighting fires upon the hills on All Saints'night, the Eve of All Souls, scarcely needs explaining, fire being, even among the Pagans, an emblem of immortality, and well calculated to typify the ascent of the soul to heaven.
A correspondent of the same periodical (1788, vol. lviii. p. 602) alludes to a custom observed in some parts of the kingdom among the Papists, of illuminating some of their grounds upon the eve of All Souls, by bearing round them straw, or other fit materials, kindled into a blaze. This ceremony is called a Tinley, said to represent an emblematical lighting of souls out of purgatory.

Good night last night. All our hedgehogs were fresh roadkill by the way, not too mashed up. Shame to let the blighters go to waste!
