asked the Secretary of State for the Colonies what progress has been made in completing the geological survey of the Southern Province of Tanganyika.

I understand that since 1948 17,000 square miles of this Province have been covered by geological reconnaissance survey and that a detailed survey has been made of about 100 square miles in the coalfield area. I am asking the Governor whether this information can be amplified and will write to the hon. Member when I have his reply.
