Owing to the inadvisability of being out of doors after dark in this neighbourhood I was not
able to visit a further unworked seepage reported to exist to the east along the same line.
The worked oil is a very dark brown in colour, rather fluid of specific grave. '960 (approx.).
It smells slightly of H 2 S. ; but has no sulphur water with it and no sulphur deposits or springs were
seen in the neighbourhood.
Within ten yards of the wells producing fluid oil there is another seepage forming a small pool
about a yard across where a thick black visccus tarry oil seeps up.
Very little gas accompanies any of the seepages. ' .
Forty-eight tins full of the oil are daily brought down on the backs of donkeys to a primitive
rehnery in the town. Out of every 14 tins of oil distilled, 8 tins of distillate are obtained, in three
grades:—
1st grade ... 3 tins ... used in lamps.

tiactor. It was not possible to visit these mines.

A brown impure looking manjak is being worked as‘coal’ somewhere in this neighbourhood
but I was unable to find out from where it came. ignoournooa,
5. GEOLOGICAL STRUCTURE AND PROSPECTS.
A. Zakho 5
South of Zakho lies the long limestone ridge of Jabal Abyadh, which the Zakho pass traverse
almost at right-angles Towards Dohuk the trend of the strike is N.W. to W.N.W. but at the pass
the strike swings round to nearly east and west towards the Tigris. ^
The section across the pass is that of an anticline with a northern limb dinning ohrmf
degrees to the N.N.E and the southern limb almost verticle. The pass appea" to âfa Lestminf
