Gandhi had given an advance notice of his "Salt March" to __________.

Read the passage and answer the question :

The volume of information being gained daily shows how wickedly the salt tax has been designed. In order to prevent the use of salt that has not paid the tax which is at times even fourteen times its value, the Government destroys the salt it cannot sell profitably. Thus it taxes the nation's vital necessity; it prevents the public from manufacturing it and destroys what nature manufactures without effort. No adjective is strong enough for characterising this wicked dog-in-the-manger policy. From various sources I hear tales of such wanton destruction of the nation's property in all parts of India. Maunds if not tons of salt are said to be destroyed on the Konkan coast. The same tale comes from Dandi. Wherever there is likelihood of natural salt being taken away by the people living in the neighbourhood of such areas for their personal use, salt officers are posted for the sole purpose of carrying on destruction. Thus valuable national property is destroyed at national expense and salt taken out of the mouths of the people.
