Concise summary:

ב׳ seifim: two dinim complete the laws of נטילת ידים for a meal. (א) מי שאין לו מים — how far must one walk to find water? ד׳ מילין ahead, מיל behind (פסחים מו.) ; beyond that he is not obliged, and יטול ידיו במפה — he wraps his hands in a cloth and eats bread or dipped food (from the mapa permitted to eaters of teroumah, חולין קז:). (ב) המאכיל לאחרים — one who feeds others need not wash (he is not eating), but the eater must, even though he does not touch the food (another places it in his mouth, or he eats with a מגרפה): the obligation lies on the one who eats, not on the one who touches ; and it is forbidden to feed one who has not washed — לפני עור.
