140 Mr. Scott on the Banks of the Tistd and Subulc. 



and the ends projecting from the opposite banks are generally nearly due north 

 and south of each other^ as represented in the lower figure of the sketch*. 

 The specimens from the banks of this river are the following : — 

 Nos. 1, 2, and 3. Friable sandstone, much resembling some of the speci- 

 mens from the Tista. In No. 2, the rounded form of the grains is evident 

 with the assistance of the lens. — The strata composed of Nos. 1, 2, and 3, dip 

 to the N. W. at an angle of about 35° or 40° : their direction is, on the south side 

 of the river, S. 35° W. ; on the north side of the river, S. 50° E. 



4. Slaty clay, inclining to bituminous shale, surrounded with coal of a dark 

 brown colour and conchoidal fracture : — found imbedded in No. 5. Proba- 

 bly the cast of part of the stem of a plant. 



5. Sandstone like the specimens Nos. 1 and 2. A second specimen, marked 

 No. 5, consists of sandstone, of the same appearance, inclosing small portions of 

 coal, with traces of woody fibre. 



6. Sandstone of a grey colour, containing numerous particles of mica, and 

 small portions of coal. The stratum. No. 6, is placed immediately above No. 5. 

 Dip and direction as above mentioned. From the north side of the river. 



7. Sandstone, somewhat like Nos. 1 and 2. Dip and direction the same. 

 From the south side of the river. 



8. Slaty clay, containing a very large portion of mica ; colour gTeenish- 

 grey : found between Nos, 7 and 9. Resembles No. 8, from the Tista. 



9. From the south side of the Subuk. Resembles No. 3, above mentioned ; 

 and approaches to the specimen. No. 9, from the Tista. 



10. Bituminous shale, with coal ; — broken from what appeared to be the 

 trunk of a tree about fifteen feet in length, imbedded in the rock. 



11. Bituminous shale ; — found under the stratum No. 12, on the south side 

 of the river. A second specimen, also marked No. 11, is soft shale of a smoke- 

 grey colour, precisely similar to the shale of the coal formation. 



12. Sandstone, of coarser grain than Nos. 3 and I : the worn pebbles are 

 here very distinct. 



Many of the strata, here enumerated, contain small rounded stones, — often 

 in thin seams, which follow the position and direction of the strata, — and 

 sometimes dispersed through the sandstone, as in the specimen No. 8 from 

 the Tista. 



* The appearances here described indicate the existence of a. fault, running in the direction of 

 the river.
