what did miss Sullivan teach Keller about nature ?

Many of Helen's lessons took place in the outdoors amidst the glory of nature,

"All my early lessons have in them the breath of the woods–the fine, resinous odour of pine needles, blended with the perfume of wild grapes. Seated in the gracious shade of a wild tulip tree, I learned to think that everything has a lesson and a suggestion. 'The loveliness of things taught me all their use.'"
