The children would sing
Taupes,cherrilles, et mulots,
Sortez, sortez, de mon clas,
Ouje vous brule la barbe et los os.
Arbres, arbrisseaux,
Donnez-moi des pomes a miriot.
Mice, caterpillars, & moles get out of my field!
I will burn your beard and bones!
Trees and shrubs, give me bushels of apples!
The children were like the coming Christ child who would drive all evil from the earth. "As the Christ Child drove away sin, so do these children drive away vermin."
Many worried about the possibility of accidents which could arise from this assembly of juvenile torch-beares, scattering "their flames around them on every side; but there is a remedy for all dangers; this fire never burns or injures anything but the vermin against which it is directed: — such, at least, is the belief of the simple folks who inhabit the department of the Eure-et-Loire." (Time's Telescope, 1828)
