Sometimes they rise rapidly, and are soon out of sight; at other times they blow along just above the ground. This habit is not confined to any particular kinds of spiders, but is practised by many small species of Erigone, and by the young of many spiders of all families, that when adult would be too large for it. The majority of spiders that fly in autumn are the young of several species of Lycosa, that seem to spend the greater part of October in trying to get as far above ground as possible. The best places to watch for them are garden- fences, where they often swarm, and can be seen more distinctly than on bushes. It is still unexplained how the thread starts from the spinnerets. It has been often asserted that the spider fastens the thread by the end, and allows a loop to blow out in the wind ; but in most cases, this is certainly not done, only one thread being visible. Sometimes, while a thread is blown from the hinder spinnerets, another from the front spinnerets is kept fast to the ground (fig. 26) ; so that when the spider blows away, it draws out a thread behind it entirely independent of the one from which it hangs. Sometimes, instead of a single thread, several are blown out at once, like a long 9.—Water Spiders. One of the most curious and interesting of the spider family is the Argyroneta aquatica, or Water-spider, which lives for the greater part of its life beneath the surface of water. Kirby and Spence give the following description of its habitation :— "It is built in the midst of water, and formed, in fact, of air ! Spiders are usually terrestrial, but this is aquatic, or rather amphibious ; for though she resides in the midst of water, in which she swims with great celerity, sometimes on her belly, but more fre- quently on her back, a
