FERNS AS A HOBBY

sciously to the plaintive, long-drawn notes of the wood-birds and the sharp "tsing" of the locusts, breathing the mingled fragrance of the mint at your feet and the pines and hemlocks overhead, you will wonder vaguely why on summer days you ever drive along the dusty high-road or eat indoors or do any of the flavorless conventional things that consume so large a portion of our lives.

Of course what is true of other out-door studies is true of the study of ferns. Constantly your curiosity is aroused by some bird-note, some tree, some gorgeously colored butterfly, and, in the case of ferns especially, by some outcropping rock, which make you eager to follow up other branches of nature-study, and to know by name each tree and bird and butterfly and rock you meet.

The immediate result of these long happy days is that "golden doze of mind which follows upon much exercise in the open air," the "ecstatic stupor" which Stevenson supposes to be the nearly chronic condition of "open-air laborers." Surely there is no such preventive of insomnia, no such cure for nervousness or morbid introspection as an absorbing out-door interest. Body and mind alike are invigorated to a degree that cannot be appreciated by one who has not experienced the life-giving power of some such close and loving contact with nature.
