[Illustration: 56. Find the frost spider] No. 45. One of the most beautiful and striking masterpieces of Jack Frost. No. 46. Singularly suggestive of a mass of white feathers thrown loosely upon the glass. No. 47. Another masterpiece from the brush of the Frost Spirit, a perfect oak-leaf design. No. 48. This is a largely magnified specimen of window-pane frost, showing examples of frost crystals greatly magnified and in detail. No. 49. Another arrangement of leaves, showing also branch-like twigs. No. 50. A very delicate pattern. Note the perfectly formed leaf design with its delicate background of feathery tendrils. No. 51. A remarkably fine feathery design. No. 52. Two very freakish specimens of frost etchings. Suggesting somewhat the artificial “flies” used by fishermen. No. 53. Like a delicate bit of seaweed. No. 54. Like a delicate powdering of small flowers, scattered over the window-pane. No. 55. Perfectly formed leaf designs. No. 56. A design worthy of study. Find the spider. No. 57. Two types. Suggesting gray moss clinging to rocks. No. 58. A very rare design. An almost perfect spider’s web, formed of thick, granular frost, with beautiful moss-like ornamentation in lighter design. No. 59. One of the choicest and most delicate designs photographed which might have formed in the ocean instead of upon a window-pane. No. 60: this beautiful etching was made in northern Vermont, and is very like a white forest of fir trees. [Illustration: 57. Two distinct types of window pane frost] [Illustration: 58. Curious design suggesting spider web, with moss-like ornamentation] MYSTERIES AND BEAUTIES OF THE SNOW [Illustration: 59. One of the choicest designs of window frost. A perfect specimen of a certain type of delicate seaweed] [Illustration: 60. A design of frost work from “the land of the pointed firs”] CHAPTER IV MYSTERIES AND BEAUTIES OF THE SNOW “Hast thou entered into the treasures of the snow? Or hast thou seen the treasures of the hail?” —Job 38:22. Most of us have given little time or very serious thought to the study of the snow, and the marvellous detail which goes to fashion the individual snow crystal. In fact, if we live in a crowded city, we are inclined to look upon a heavy snowfall as something of a nuisance, to be shovelled and carted away as expeditiously as may be by the army of men employed by the city for that purpose. There it lies, soiled and unlovely, impeding pedestrianism and traffic, and thoroughly undesirable until it is cleared away.
