A sloped סוכה with no separate roof (and רב יוסף's bridal canopy), and when a reed mat may be used as סכך
Overview
This amud opens by finishing an earlier discussion: טיט הנרוק proves that something unfit by itself can still help something else become fit. Then a new משנה starts. A סוכה shaped like a sloped hut (צריף), or leaned against a wall, has no separate roof. רבי אליעזר says it is פסול, and the חכמים say it is כשר, because שיפועי אהלים כאהלים. אביי finds רב יוסף sleeping under a sloped bridal canopy in the סוכה and challenges him for following רבי אליעזר. רב יוסף answers that a ברייתא reverses the names, and that the משנה's version is only רבי נתן's. Another משנה teaches that a reed mat made for lying on is a כלי and cannot be סכך, while one made for roofing is valid. The גמרא finds a contradiction about a mat made with no stated purpose. רבא concludes that everyone agrees an unlabeled large mat is for roofing. For a small mat, the תנא קמא presumes it is for lying, and רבי אליעזר presumes it is for roofing.
Opening lines
טִיט הַנָּרוֹק יוֹכִיחַ,
Pourable mortar will prove it,
שֶׁמִּצְטָרֵף לְאַרְבָּעִים סְאָה,
for it combines toward forty se'ah,
וְהַטּוֹבֵל בּוֹ — לֹא עָלְתָה לוֹ טְבִילָה.
yet one who immerses in it, his immersion is not valid.
