Embedded at the corner of a grass-plot across the street was a whitewashed stone, the size of a small watermelon and serving no purpose whatever save the questionable one of decoration. It was easily pried up with a stick; though getting it to the caldron tested the full strength of the ardent labourer.

Perspiring, grunting vehemently, his back aching and all muscles strained, he progressed in short stages until the big stone lay at the base of the caldron. He rested a moment, panting, then lifted the stone, and was bending his shoulders for the heave that would lift it over the rim, when a sweet, taunting voice, close behind him, startled him cruelly.
