QUEEN MARY'S CARPET.

The carpet given by Queen Mary to the nation will shortly start on its way to North America where it is to be sold as a contribution to the dollar drive. Before the closing date for bids, it is to visit some. 20 Canadian and American cities where it will be placed on exhibition.

The safe-keeping of the carpet on its travels has naturally been a matter of great concern to the Committee entrusted with its disposal.. Police arrangements are being worked out with the authorities of each of the cities it will visit.

NEW 125-TON PLASTIC PRESS

The largest industrial building constructed in timber in Britain, since the war has been opened at Kingstan Wharf, Shortham, Sussex, for timber storage.

Fifty-dva tons of timber have, done the work of 79 tons of steel, representing a saving in tonnage of over 30 per cent.
