56 The Structure and Habits of Spiders.

 afterward. In favorable places these webs re-

 larged, as the spider grows, by additions on the 

 outer edges, and are supported by threads run- 

 ning up into the neighboring plants. Similar 

 webs are made by several house-spiders, and 

 are enlarged, if let alone, till they are a foot or 

 two feet wide, and remain till they collect 

 dirt enough to tear them down by its weight. 



Nearly all spiders that make cobwebs live

 The spiders of the genus Linyplna make a 

 flat or curved sheet of web, supported by 

 threads above and below ; the spider standing,
