Back in grammar school, and probably in Jr. High & High School as well, I
remember solving a class of puzzles I haven't seen since.  The general format
was a short description of the situation, followed by several (10 to 15)
statements about individual clues to the answer.

For instance, there's one about 5 different colored houses, whose inhabitants
were of 5 different nationalities, smoked 5 different brands of cigarettes,
had 5 different kinds of pets, and drank 5 different types of liquid.  The
question that was to be answered was "Who drank water and who owned a zebra?"

The reason I remember it even this well is that I remember how I solved it:
by drawing 5 5x5 matricies, and marking the elements based on the clues given
(like "The Englishman did not smoke Parliaments." or "The man in the red
house drank scotch." or "The man next to the brown house was allergic to
cats.", etc.).

Can anyone out there in puzzle land either provide me with these sorts of
puzzles or a source for same?

	Thanks much,
