The explanation of the former seems to be that the branches from 

 the north carried in much more material than those from the south. The 

 tributaries from the north are more numerous and larger than those from 

 the south and carried into the valley great quantities of glacial material 

 from the foot of the ice-sheet or material from the .slopes near its foot. 

 This caused a greater accumulation of sediment on the north side of 

 the valley, and the deltas thus formed drove the stream to the south side 

 of the valley. The deltas of Buck and Wolf creeks, for example, extend 

 nearly across the valley to the south side. AVhere Mt. Tabor, or Ellet's 

 Hill, protected the valley from glacial or upland sediments from the north, 

 the channel tinds its way to the north bluff. To sum up, it seems from the 

 foregoing statements that tlie creek keeps to its south Iduff because of 

 accumulated material fi'om its tributaries in the north side of the valley. 



The answer to the other (luestion. Why are tlie valle.\ slopes steeper 

 south of Bean Blossom than north of it? seems to be as follows: It was 

 observed that the variation in the slope had a direct relation to the minute- 

 ness of dissection, or the spacing of the streams crossing it, and that the 

 closer the streams are to each other, the more subdued the slope. As a 

 greater number of streams cross the valley slope on the north side of 

 the valley Ave tind the more subdued slopes on that side. In addition 

 to this the stream occupying the south side of the valley has confined 

 its side-cutting to that side whicli has tended to keep these bluffs steeper. 



Mineral Rksources. 



The priiiciiial mineral resources are rock, sands and clays. The rocks 

 having been mentioned as to use and value, the sands and clays remain 

 to be discussed. 



Sand. 



Tlie sand of the area is in the vicinity of Mt. Tabor, and between that 

 point and Gosport. This sand is very fine and flour-like and, consequently, 

 it is not a plastering sand. However, it is a good quality of moulding 

 sand and may be used for paving purposes. For these purposes it has 

 been satisfactorily tried, several car loads being used. There is, besides 

 detached patches, a continuous sand area covering several square miles 

 to a depth of 20 to 40 feet.
