He had hoped that the heads of the oil industry, would be able to help "embarrassed Ministers" to find some way out of the present difficulties of the coal trade.

The New Building. Every Londoner must envy those who in future will have their off ece in the magnificent building There are 16 lifte to whisk them from floor to floor, at the rate of 500ft. a minute; the walls of the passages and halls are of polished Portland stone, which might be. called a British substitute for marble; and the great oil-burning boilers in the basement will warm the house to the right temperature in any weather.

The clock, which has longer arms and a wider face than Big Ben, stands as a monument to modern architecture and design, as much as the rest of the building repre-

sents the achievements of modern engineering.
