CHART 1 



Horizontal distance on the chart is horizontal distance along the 

 shore. Vertical distance on the chart is vertical distance on the shore. 



Fig. 1. Relative vertical width of the Fucus zone from north of the 

 Station laboratory to south of Newhall's wharf. The lower graph marks 

 the lower limit of Fucus, and its lowest point is the low-tide line. The 

 upper graph marks the upper limit of Fucus, and its highest point is about 

 3/o meter below the high-tide line. Distance between the two graphs there- 

 fore is the relative vertical width of the Fucus zone along this shore. 



Fig. 2. Relative width of the Fucus zone in the Point Caution region 

 from the rocky point townward from the streamlet to a point about 40 

 meters north of the cove in which the telephone cable enters the water. 

 The lower graph marks the lower limit of Fucus, and its lowest point is 

 the low-tide line. The upper graph marks the upper limit of Fucus. and 

 its highest point is about ^ meter below the high-tide line. Distance be- 

 tween the two graphs therefore is the relative vertical width of the Fucus 

 zone along this shore.
