through the language of blinds called braille

Answer 2

Miss Sullivan preferred teaching Helen out of doors in close proximity with nature . Miss Sullivan ensured Helen touched each and everything she learnt. One of their favourite learning spots was Keller's Landing, an old wharf on the Tennessee river, where Helen learnt Geography. There Helen made dams of pebbles, islands and lakes, dug river beds while Miss Sullivan described the physical and topographical features of the round world. Miss Sullivan would describe to Helen the burning mountains, buried cities, moving rivers of ice, etc. She made raised maps in the clay in relief so that Helen could feel the mountain ridges, valleys, and the devious course of rivers. She learnt Science and History in the same manner. Once a gentleman sent her a collection of fossils. Miss Sullivan made Helen touch the fossils, and as she did so, she would describe to her the description of the dinosaurs. Helen would see those gigantic beasts tramping the
primeval forests in her imagination and wonder at their enormity.
