Show Heart of the Hailstone. If It wcro not for tho countless trll- lions of dust jiurtlcles that float, separately sep-arately Invisible. In the atmosphero. thero could bo no rain drops, snow crjBtnls or hailstones, From n perfectly per-fectly dustless ntmosphoro tho mols-turo-would descend In ccasolcss rain without drops. Tho dust particles servo as nuclei about which tho vapor gothers. Thu snow crystal Is tho most beautiful crentlon of tho aerial molsturo, and the hallstono Is tlio most extrnordl. nary. Tho heart of every hallstono Is a liny atom of dust. Such nn atom, with a llttlo moisture condensed nbout it. Is the gorm from which may grow n hallstono callable of felling a man or smashing a window. But first It must bo cnught up by a enrront of nlr nnd carried to tho lovol of the lofty cirrus clouds, flvo or Blx or oven ten miles high. Then, continually contin-ually growing by fresh ncosslons of moisture, It begins Its long plungo to tho earth, spinning through tho clouds nnd (lashing In tho sun llko a diamond bolt Bhot from a rainbow. |
