Mr. Hughes has resumed operations at the tin exploitation in Tenasserim. Dr. Warth, on joining the Department, has been placed with Mr. Hughes.

Mr. Griesbach left Calcutta for the N. W. Frontier in November; but has since been posted as Geologist with the Miranzai Expeditionary Force.

Mr. Oldham succeeded in verifying the reported occurrence of oil at Mogulkot, in the Sherani country, before the withdrawal of the late Zhob Valley Expeditionary Force. The oil is of fairly good quality, and issues from the springs at about 10 gallons a day. The laboratory examinations of this oil, owing to uncertainty as to the procuring of the samples sent down before Mr. Oldham's visit, are still conflicting: so that a more thorough examination of the springs and their geological conditions will have to be made, when opportunity for further survey occurs.
