There's more than the 101-seater dining table at the Falaknuma Palace that is awe inspiring. The library done in rosewood and mahogany is a place that will force anyone to pause, if only to admire the fine original polish, the furniture and the walnut carved high roof. The last is supposedly an imitation of the one at Windsor Castle.

The library is almost the size of a large banquet hall and acts as the passage to other parts of the palace including the dining area. For years the palace had no librarian because they couldn't find the right person to do justice to the treasure trove of books collected by the Nizam's family over several decades. That is until they found Asif Husain Arastu who belongs to the family that owned the famous A A Husain book store in Abids. So when his friend and historian Anuradha Naik pointed out the palace's requirement at the library, Husain was delighted. On his very first day as the librarian at the magnificent Taj Falaknuma palace, Asif Husain found a reference book on 'How to paint grass' by Alfred East.

Name the author of the book that Mr Hussain found on his first day as the librarian?
