Skilled at agriculture and hunting, then Taínos were also good sailors, fishermen, canoe makers, and navigators. Their main crops were cassava, garlic, potatoes, yautías, mamey, guava, and anón. They had no calendar or writing system. Their personal possessions consisted of wooden stools with four legs and carved backs, hammocks made of cotton cloth or string for sleeping, clay and wooden bowls for mixing and serving food, calabashes or gourds for drinking water and bailing out boats, and their most prized possessions, large dugout canoes, for transportation, fishing, and water sports.
