* Jonathan Allan pointed out to me that a simpler way to proceed at this point is to note that rules 3 and 13 put the tea and beer drinkers in houses 2 and 5, leaving the water dri nker in house 1.  Then rule 15 can be used in the next step to put the Blend smoker in house 2.  After that, the rules fall like a house of cards without the need at any point to apply more than one or two rules at a time.  But I already made these lovely charts, so I'll keep the sequence as it has been, with the thunderous application of four rules at this point.
