 continuing them through the bark to the outside of the 

 trunk. Before transforming, they line these passages with 

 a web of silk, and retiring to some distance from the 

 orifice, they spin around their bodies a closer web, or

 As they increase in size, they enlarge their web until

 grown, they measure something over one inch in length. 

 In early autumn they leave their web and for the first time
