 such materials as may be accidentally obtained, such as 

 thread, string, yam, wool, and bits of cloth, aU of which are 

 firmly interwoven. Though its structure and shape exhibit 

 much variation, yet it is usually enlarged near the bottom and 

 warmly lined, most often with hairs. It is frequently built
