[When] the partition is built on the floor and tumah is inside the partitioned sec-tion, utensils inside the house become tamei. When tumah is inside the house and utensils are inside the partitioned section, if the area containing the utensils is a handbreadth by a handbreadth and a handbreadth high, [the utensils] remain tahor. If not, they become tamei, because the floor of the house, as deep as one can go, is like the house.
