Are you sure that spelt has less protein than modern wheat. I had the impression it was as good or higher. I know that short grained rice has a higher protein comtent than long grain rice.
A cacique is a native chief. I have used on line dictionaries to try to translate Spanish language newspaper articles. I find they only define about 1/2 the words I am looking for. May Spanish is already reasonably good, so these are the less common words. There is a dictionary by Cuyas that is like the Webster for Spanish.
Appreciate the definition of cacique.
