over M'ere deposited. Farther east Osgood Brook, in Wendell, has heavy 

 sands at its south end, while, as before, the open valley to the north extend- 

 ing to the Millers River Valley is bowlder-covered and free from sands. 

 These sands terminate a little farther north than those last mentioned. 



Next east one may follow up the deep V-shaped valley of Wickett 

 Brook from where it joins jMillers River south and find it, although well 

 fitted to retain sediments and altliough continued north of Millers River in 

 a deep valley, to be bowlder-covered to the water's edge. At a point a 

 little north of the one reached in the last brook, the high-level bowldery 

 gravels (1 s) begin and increase and accompany the brook south to its 

 headwaters west of Wendell Center and beyond, and, passing over the col 

 in the deep continuoiis valley, they continue south to join the heavy sand 

 beds north of Locks Pond. 



On the next brook east — a second Osgood Brook — the brook bed is till 

 covered to a point nearly as far south, and then sands commence which run 

 np the valley, increasing as the brook lessens, and, passing its col in the val- 

 ley, as before, they are continued down the valley of Swift River. The 

 streams which enter Millers River from the north, across Erving, opposite 

 those described above, have inconsiderable sand deposits. Furthermore, 

 the Millers River Valley up to Wendell station has small deposits of 

 high-level sands. With the next brook east, however, this is changed. 

 The brooks thrust extensive deltas into the valley, and from this point on 

 east the drainage was plainly eastward into the Orange basin, as will be 

 detailed below. 



Examining the upper waters of the first brook east (Moss Brook) com- 

 ing down from the north, we see the sands begin on its western tributary 

 a half mile above Harris Pond, and on the main stream at the mill pond 

 (Lake Moore) southwest of Warwick Center, while the valleys above are 

 empty of sands. Below these points the stream is bordered by heavy 

 gravels and sands (1 s), flat topped, with a width for a long distance of 150 

 rods, expanding in the southwest of Warwick to a triangular sand ])lain 

 more than a mile on a side before it enters its narrow gorge to reach the 

 main valley. 



Following the brook still farther north through the narrow valley 

 south of I\Iount Grace, we soon find it again bordered by broad sands, 

 ^vhich expand to an extended sand plain that continues north of Warwick 

 iDeyond the headwaters of this brook and that is soon trenched by the
