THE WAKE AND SWIFT ItlVKK LAIvKS. 573 



From Wendell depot up (b'-, PI. XXXV, C), the liig-li level sj.ii.ls were 

 formerly plainly continuous across the valley. Their inner structure indic;ites 

 a flow to the east and their upper surface slopes in this direction. They 

 are about 90 feet high at the Moss I3rook delta. At tlie Scotts or Orcutts 

 Brook delta, next east and opposite this latter, they extend down the 

 Holshire Road Valley, the next \alley on tlie soutli parallel to and west of 

 the main channel, at a height of 75 feet above the plain, tilling this vallev 

 with a great l)ody of sands and gravels, which are beautifulh- kettle-lioh-d 

 south of North Pond, and which extend south to join tlie main ( )rantie- 

 Eniield channel in New Salem. 



The high sands which thus till the Holshire Koad A'allcv extend ronnd 

 the north spur of Wahuit Hill, which separates this vallev from rlie main 

 Orange Valley, and project out freely into the hitter in a d(dtii which 

 matches that at the other corner and which nlong the north si(h' of the 

 river is confluent witli the delta of Fall Hill Brook, on wliich tlie cemeterv 

 is built. 



A section of the sands east of Orange showed a great thickness of fine 

 sands with the cross-bedding dipping eastward; above this a bed, about 2 

 feet thick, of very fine sands. This was covered in turn with coarse sands 

 of about the same thickness, the boundary between tlie two Ix-ds being 

 very irregular and the structure indicating a delta front ad\-auciug from 

 the west. 



The last halting place of the ice in tlie Swift River drainage area. — The 

 position of the ice on Millers River at the time of this last eftective flood- 

 ing of this portion of the area can be closely fixed at Wendell station (b'"), 

 and the coincident ice front can ])e traced across from the Connecticut to 

 the northeast corner of Warwick by the following considerations: 



Groingup Tannery Brook (a branch of Goddard Brook) from ^lontague 

 village, one comes at the "height of land" on a broad area (1 p") of heavy 

 sands and gravels southwest of Dry Hill, bedded and with irregular surface. 

 They extend down to wdiere ice filling the Connecticut ^'alley would 

 have stopped them, and there end abruptly. Off" to the south a col west 

 of Chestnut Hill determined their height and provided for their outflow; 

 to tlie north they end at a schoolhouse (1)", PI. XXXV, C), and here one 

 can look north down an open bowlder-covered valley, wholly free from 

 sand, which must have been filled with ice when the sand beds just passed
