270 J. D. Dana on the Quartzite, Limestone, elc., 
_ The only place in the outcrops of quartzite near Canaan, 
where the stratification is distinct, is in the northeastern of the 
patches, Nos. 5 and 6. (I reproduce here the map of the region, 
prepared for me by Mr. Adam.) I still find, on a re-exam- 
quartzite itself, the angle being N. 60°-65° W. at the north- 
west end, N. 45° W. at the middle, and N. 30° W. at the south 
ly 
west of the southeast end of the quartzite, the di of the lime- 
stone is N. 35° W. i 
quarry,* or that there is a fault. Seventy-five yards farther 
to the northeast, the limestone outcrops again, with the strike 
N. 53° W., and dip to the northeastward as in the other 
* No. 3, page 261.
