the best experienced by builders durings recent years in the mat- ter of bookings. Including "Ad- miralty work, the number of new contracts fixed up by Clyde ship- bullders totals twelve, and the money represents something like 3,000,0001. There are other in- market and the quiries in the outlook is certainly very promis- Ing. During the month the out- put from Scottish yards was seven vessels of 8,061 tons. of this total, the Clyde had six vessels of 8,741 tons, and the Dee one vessel of 220 tons.

PROGRAMME

We are glad to be able to an- nounce that the Admiralty have awarded a contract for a 5,200- ton cruiser to Messrs. Harland and Wolf, Limited, Belfast. This vessel, which will be known es H.M.S. Penelope, forms part of the 1933 Naval Construction Programme,
