Show Traveling Methodo of Spiders. "It Is well known," says tho Itovuo Sclcntlflque, "that certain spiders can bf- transported by tho wind, owing to i very slight silken thread that they mlt from tho spinneret which Is blown along by an ascending current nf air. A thread a yard long, accord-b'g accord-b'g to tho experiment of M. Favlor, can sustain tho weight of a young spider. For many years M. Favler i:as wltncssod every spring tho dispersion dis-persion of young Bpldors from a largo number of nests. In a fow hours, In favorable weather, a thousand young ones will set out from tho same nest to begin their' travels. Tho spider Is not absolutely passive, but can renu-lata renu-lata Its ascent, both at Its departure and during tho Journey. It Is Biisn-dent Biisn-dent to Incrcaso tho length of tho string to mount more quickly and to fchorten It when wishing to alight. Possibly certain hibernating species may accomplish a sort of periodic emigration by this means." |
