At first he looks at them and says "Schwarze" which is German for "black" or "blacks" but probably is the same in a few other languages. I think he's saying a bit of German at the end. My German is a little rough, but if memory serves, he said something like: "Hast die den gesehen in deiner Leben?" Which translates roughly to: "have you ever seen people like that in your life?" At the end, he's speaking plain old English "They darker than us! Whew!"

"The bead work on Brooks' Indian headdress in the movie poster says "Kosher for Passover" in Hebrew (kosher l'pesach) (although jokingly misspelled; it actually reads "Posher for Kassover" (posher l'kesach). When Brooks is speaking 'Indian', he's actually speaking Yiddish."
