I beg to acknowledge receipt of your letter dated 29th September, and previous to this I had received one letter from you also. Now I may inform you that Nara Narayana has already gone to Calcutta especially for the purpose of making a model of Mayapur construction work. So immediately you can contact him. Regarding the other models like New Vrindaban, L.A., N.Y., Dallas, he can make models provided there are photographs of different buildings. So you contact him and do the needful.
