the archaic well-sweep in his front yard; but the wise men answered that stones do not shrink. Its heat lingered persistently, and Nahum declared it had glowed faintly in the night. The professors tried it with a geologist's hammer and found it was oddly soft. It was, in truth, so soft as to be almost plastic; and they gouged rather than chipped a specimen to take back to the college for testing. They took it in an old pail borrowed from Nahum's kitchen, for even the small piece refused to grow cool. On the trip back they stopped at Ammi's to rest, and seemed thoughtful when Mrs. Pierce remarked that the fragment was growing smaller and burning the bottom of the pail. Truly, it was not large, but perhaps they had taken less than they thought.

The day after that—all this was in June of '82—the professors had trooped out again in a great excitement. As they passed Ammi's they told him what queer things the specimen had done, and how it had faded wholly away when they put it in a glass beaker. The beaker had gone, too, and the wise men talked of the strange stone's affinity for silicon. It had acted quite unbelievably in that well-ordered laboratory; doing nothing at all and showing no occluded gases when heated on charcoal, being wholly negative in the borax bead, and soon proving itself absolutely non-volatile at any producible temperature, including that of the oxy-hydrogen blowpipe. On an anvil it appeared highly malleable, and in the dark its luminosity was very marked. Stubbornly refusing to grow cool, it soon had the college in a state of real excitement; and when upon heating before the spectroscope it displayed shining bands unlike any known colors of the normal spectrum there was much breathless talk of new elements, bizarre optical properties, and other things which puzzled men of science are wont to say when faced by the unknown.

Hot as it was, they tested it in a crucible with all the proper reagents. Water did nothing. Hydrochloric acid was the same. Nitric acid and even aqua regia merely hissed and spattered against its torrid invulnerability. Ammi had difficulty in recalling all these things, but recognized some solvents as I mentioned them in the usual order of use. There were ammonia and caustic soda, alcohol and ether, nauseous carbon disulfide and a dozen others; but although the weight grew steadily less as time passed, and the fragment seemed to be slightly cooling, there was no change in the solvents to show that they had attacked the substance at all. It was a metal, though, beyond a doubt. It was magnetic, for one thing; and after its immersion in the acid solvents there seemed to be faint traces of the Widmänstätten figures found on
