If the web gets damaged the spider knows how to repair it. 

 I once made a hole in one of these webs, through which a golf 

 ball might have been passed with ease. This was done at 

 about 7 p.m. At 9 p.m. I noticed that the ragged edges of the 

 rent had been roughly drawn together, and by 11 p.m. some 

 more work had been done, in such a position that I could not 

 observe any details ; but in the morning the hole had been 

 darned ; not as well as the original weave, but still a distinct 

 darn, and the violated circle had been restored.
