1:5

Beis Shammai says: one may not remove a door (cupboard door? see Beitzah 11b) on a festival Beis Hillel permits it, except for putting it back. Beis Shammai says one may not crush meat with a pestle on a festival. Beis Hillel permits. Beis Shammai says one may not place a hide in the path of tramplers, (i.e. using it as a doormat) and one may not lift it up, unless with it there is an olive's volume of meat. And Beis Hillel permits it. Beis Shammai says, one does not take out a small child or a lulav (the ripe green frond of the date palm that is waved on Succos) or a Torah scroll into the public domain. Beis Hillel permits.
