continued, would pass down a precipitous hill and across Parker brook 

 into a swampy forest. 



The next (Fig. 39) is the most important of all the sections, partly 

 because it is near the travelled road to the Connecticut river west from 

 Littleton village, and partly because it comes from Sec- 

 tion IX. It is a mile and three eighths long. The gneiss i 

 is the Oak Hill deposit, and is in place an eighth of a ; 

 mile north of the section, with a dip of 3 5^-40° N. 30° i 



W. The chloritic rock appears next. It is close by the -" F^i^lili I 



n 

 road, opposite the last house before reaching the Parker | 



brook, and can be traced along the ridge extending north- g 



east for one fourth of a mile. The dip is 60° N. 60° W., - 



with a somewhat higher dip down the slope. The fossil- | x 



iferous limestone follows immediately. The first layer '^ ^ 



seems to conform with the wall rock. At the kiln, which gw 



is not fifty feet from the base, it dips 60° N. 85° E., and |f 



also westerly. Hence there is a small anticlinal axis. The 3 >- 



same fact was also observed farther north, near Fig. 38. '^ | 



Directly at the kiln no fossils were obtained : they came 9 s 



from a dark layer, with a westerly dip, near the brook. | 'J, 



The Zaphrentis and the Favosites, with small crinoidal | ^ 



fragments, are found here. Geologists have searched for h %. 



fossils at the kiln, and, finding none, have concluded that \- 



our story about them is a myth ; but they should look in "^ 



the right place. Dr. C. T. Jackson visited this kiln in | 



1 84 1. He says, — "The bed is included in mica slate, em- ^^ 



braced on both sides by granite, which crowded the lime- | 



stone in such a manner as to produce contortions of the ^ 



strata. The course of the limestone, as indicated by ^ 



strata marks, is N. 20° E., S. 20° W., and its dip is to the 



north-west." He figures the bed as enclosed between two masses of 



granite, but does not exhibit any contortions in the strata.* 



The alluvium of Parker brook intervenes, and conceals the rock for an 



eighth of a mile, perhaps. On the south-west side there are several out-
