Regulations concerning victuals, where they may or may not be deposited to retain their heat for the Sabbath.
Mishna I.: Wherein may hot vessels be deposited (to retain the heat) and wherein may they not? Depositing in Gepheth (olive waste), dung, salt, lime, and sand, either wet or dry, is not allowed. In straw, grape-skins, wool-flocks, or grass it is permitted, provided they are dry, but not when they are still wet.
