702 WOODWORTH AND MARBUT 



accumulation along the line of the moraine, though the line lim- 

 iting the bowlder-dotted till plain on the one hand and the sand 

 and gravel plain on the other is more marked, for a short dis- 

 tance, than it is between Cat Rocks and the Queen's Kitchen. 



From the latter place the moraine turns almost due north- 

 ward and is easily traced for about two miles. It lies along the 

 slope where the higher till-covered plain west of the moraine 

 descends to the lower sand-covered plain east of it. Bowlders 

 are scattered thickly over the slope but they are accumulated 

 very little more along the outer margin than further back. 

 Spurs of the upland, however, which extend out eastward beyond 

 the moraine do not carry many bowlders. 



About half a mile south of Frenchtown, the line apparently 

 turns westward along the southern slope of a valley occupied by 

 an eastward flowing stream. An attempt was made to find the 

 moraine north of the valley but it could not be found. The 

 country as far north as Natick on the Pawtuxet River was 

 searched but it was not found. The river was followed up to 

 half a mile above Coventry. Here a line of bowlders crosses 

 the river, having a northwesterly trend, but no attempt was made 

 to follow it in either direction. 



Extensio7i south of Cat Rocks.- — The moraine was traced south- 

 westward from Cat Rocks to within about three miles of Wyo- 

 ming in the town of Richmond. Over the greater part of the 

 distance it is a fairly-well marked feature, though it never 

 assumes the phase so well developed at Cat Rocks. As a rule, 

 the relations of the morainal and the extramorainal areas are 

 essentially the same as they are north of Cat Rocks. North and 

 northwest of a somewhat irregular line lies a plain of typical 

 bowlder till on which bowlders are most abundant along the 

 southern margin ; south and southeast of it lies a region whose 

 valleys are partly filled with water-laid drift, and whose higher 

 lands consist of rounded hills and ridges carrying very few 

 bowlders. The general relief is the same on both sides of the 

 line. The glacial deposits are not thick enough to hide the pre- 

 glacial topography. The contrast in appearance between the
