Reference for Bava Metzia 203:5

לא צריכא בחצר דמשכיר ותורי דאתו מעלמא קמו בה

THE DUNG BELONGS TO THE LANDLORD, AND THE TENANT IS ENTITLED ONLY TO THAT WHICH ISSUES FROM THE OVEN OR THE POT RANGE. To what does this refer? Shall we say, to a courtyard which was rented to the tenant, and to oxen belonging to the tenant, then why is it [the dung] the landlord's? But if a courtyard which was not leased to the tenant,<span class="x" onmousemove="('comment',' I.e., he had rented the house only. ');">⁵</span>
