Question

what did charley do to make sure that he was in the third level?​

Answer 1

When Charley reached Third Level of the Grand Central Station, he found everything delved deep in the old style. In order to confirm, he went to the shop at a newspaper seller. He glanced at the stack of the papers and saw a newspaper named 'The World' of June 11,1894. This confirmed that he was in the year 1894.
