אביי said: Here we are discussing the case of a tree that is standing, etc. - אמר אביי הכא באילן העומד כולי
Summary:
תוספות maintains that רב חסדא agrees that in a רה"י a 'מקום ד is required. It is just that a regular רה"י automatically has a 'מקום ד (almost) everywhere since ביתא כמאן דמליא דמי. Only in the case of חור כ"ש do the רבנן say that there is no 'מקום ד, since the wall is all closed up, and we do not maintain חוקקין להשלים.
If it is wide six טפחים he is פטור, etc. - רחבה ששה פטור .
Summary:
The view of the ר"ח is that in order to render the כוורת a רה"י, there must be an inner area of דע"ד. Concerning the height there is no need for 'אויר י,
Our תוספות disagrees with the ר"ח, and maintains that even concerning the width of a רה"י, we can combine the walls of the כוורת with its airspace to accord the כוורת as a whole, the status of a רה"י, because we may place a board over the entire כוורתת which will give us a מקום חשוב דע"ד להשתמשות.
If it is wide six טפחים he is פטור, etc. - רחבה ששה פטור
Summary:
אביי maintains that in order to be valid, an עקירה והנחה must take place in a proper רשות where there is no changing of the status of the רשות at the moment of עקירה והנחה. However ר' יוחנן questions whether this is true in all instances, or perhaps it is true only by עקירה.
He inverted the כוורת to land on its opening - כפאה על פיה
Summary:
In order to extend מחיצות that are less than ten טפחים to be considered as if they are ten טפחים high, through תורת לבוד, it is required that there be valid מחיצות of שבעה ומשהו that are רואה פני האויר, otherwise we do not say לבוד.
Seven and a half טפחים; he is פטור, etc. - שבעה ומחצה פטור
Summary:
When the inverted כוורת which is גבוה שבעה ומחצה ורחב ששה descends to within three טפחים from the ground, two rules apply to it; 1) תורת לבוד to extend the walls and height of the כוורת another three טפחים to accord it the status of a רה"י, and 2) It is considered as if it came to a complete landing and is considered to be at rest on the ground.
