Bava Metzia 82: Responsibility for a Broken Barrel - is an Oath Appropriate?

A very brief account of today's daf:

• we end Perek VI
• new Mishna: 
• If a person is hired to transport a barrel of wine and the barrel breaks, whether an unpaid or paid baliee, this person should take an oath regarding his/her innocence.
• Rabbi Meir and rabbi Elazar (thought the Mishna teacher that this was Rabbi Eliezer, who lived in a very different time)
• The rabbis discuss different circumstances which might cause the labourer to be negilent
• The rabbis discuss different circumstances where the labourer might be forced to take responsibility
