3(34 R. CHALMERS — BAY OF FUNDY COAST IX THE GLACIAL PERIOD. 



1. Unstratified bowlder-clay, with three or more thin seams or layers 

 of clay and sand interst ratified therewith. It contains pebbles and bowl- 

 ders of call sizes up to '.» inches or a foot in diameter, some of which are 

 striated. Theseams of clay and sand dipslightly northward or away from 

 the sea. The uppermost parts contain a good deal of sand, and have 

 apparently been worked over in the Saxicava sand period. The surface 

 of the ground is strewn witli bowlders from 2 feet in diameter downward ; 

 total thickness, 12.7 feet. 



2. Typical, unstratified bowlder-clay, containing numerous glaciated 

 bowlders and pebbles; bowlders from 3 to 5 and 6 feet in diameter are 

 common; thickness, 25 feet. 



3. Stratified, tough, dark-red clay, forming a wavy, lenticular seam, 

 distinctly laminated, the strata dipping slightly northwestward, hut 

 irregular and uneven, and not occupying a continuous horizontal posi- 

 tion, except very locally. To the west of the section it decreases in 

 thickness and runs down to within a few feet of the bottom of the bank; 

 to the east it first rises somewhat higher and then descends likewise, 

 diminishing in thickness till only a foot or two of it can he seen. It c< >n- 

 tains a few pebbles, and occasionally a bowlder — one 10 inches in diam- 

 eter was noticed. No fossils were detected in it ; thickness in the thickesl 

 part, 14 feet. 



4. Unstratified bowlder-clay, the same as number 2. Bowlders 3 to 

 6 feet in diameter are numerous. These are strewn along the foot of the 

 hank as well as upon the beach. The total thickness of this bed is from 

 9 to 10 feet. 



Following this lied (number 4) of bowlder-clay continuously westward 

 from the line of the section we find it, at a distance of 15 paces, resting 

 on the glaciated ledges. Here it is observed, however, to have only a 

 thickness of from 3 to 5 feet. The stratified seam overlying it has. as 

 stated above, also thinned out here, but is, nevertheless, well defined. 

 Striated rocks, with tins bed of bowlder-clay reposing on them, extend 

 continuously along the shore for about 90 yards farther west. There 

 is much variation in the direction of the striae. Eight or more different 

 courses of them occur on these ledges, varying from S. 2° W. to S. tio° E. 

 (true meridian). These, it is evident, must all have been produced by 

 the glaciers which laid down the bottom portion of the bowlder-clay 

 (number 4 of flic section); for before the ice which deposited the upper 

 portions of the unstratified beds uumbers 2 and 1 of the section) could 

 have striated the rock- it would have to work over the whole of the 

 deposits beneath it. thus destroying all stratification therein and reduc- 

 ing them to a pell-mell mass.
