companion plants cling with vigorous energy; 

 the soft is that which is carved into tide-pools 

 to become the homes of numerous animals as 

 well as plants. 



Examining closely these roughened rock 

 surfaces it is noted that the hardened ridges are 

 associated with the cracks or joints of the rock. 

 It can be reasoned that these openings facilitate 

 the mingling of waters along the crevice walls 

 as well as their flow upward or downward as the 

 ground waters ascend or descend in their course. 

 Added waters facilitate the crystallization of 

 mineral particles whether they are newly added 

 to the mass or older material already there. 

 This molecular change forms a compact cement 

 for the sand grains involved in it. As the 

 trickling waters continue to make their way the 

 zone of cemented sand grains becomes wider 

 and wider until very perceptible hardened 

 bands can be followed where the waves and 

 weather have worn the rock. Such is the case 

 at the interesting "Chair of Neptune" near 

 Johnson's cabin.
