Well the Eskimos  send their Outboard Motors to Seattle for
repair:

The repair mechanics are continually amazed at the emergency
repairs the Eskimos had made.

Possibly this indicates some kind of intelligence that the
Eskimos possess?

Eskimo, "I have been told",   is a word that means "He eats
meat"
