Bell 2/24/13

Classes are about 45 minutes long.  About every 45 minutes, the bell rings to tell students to go to the next class.  We don't have a computer or an electronic bell since there isn't electricity most of the time.  The secretary keeps a timer, and she rings the bell herself.  Actually...we don't really have a bell.  We have a tire rim and a rock to hit against it.  It works!
