is about ten feet. In its present attitude the axis of the spit 

 inclines toward the southwest or slightly down the bay. A ref- 

 erence to the accompanying sketch plan will show the present 

 existing conditions. There is a central triangular terrace at 

 water level, marshy, but filling with sand which drifts in or is 

 washed in by rains or waves. Bordering this are two distinct 

 sand ridges rising about 2 feet above water-level. The outer 

 ridge has imponded a small amount of water between itself and 

 the inner ridge. A third ridge has been begun on the outside of 

 these two. 



Referring to the general map, it will be seen that effective

transportation must always be by winds blowing nearly parallel 

 to the axis of the middle section of the bay. The present shore 

 line, both above and below, is certainly just as irregular as it is 

 here — it would be described as slightly wavy. There is no 

 stream discharging near here, and there is no evidence of a local 

 landslip having modified the shore line in such a way as to cause 

 the beginning of the building of the spit at this point. In the 

 field it was at first very difficult to' see in this case why it should 

 have happened to be formed here and not at a half-dozen other 

 apparently similar places. It happens, however, that there is a: 

 very slight, though noticeable, difference in the curvature of the 

 shore line at this place, and it seems as if, under certain special 

 conditions of wind-action from the east of north, the longshore 

 wave and wave currents first started to build a terrace and later- 

 a bar outward from the slight salient in the shore line of this 

 point, and that the same waves gradually turned the end of this 

 free bar as it reached deeper water, giving it its curved form, and 

 finally tying it on to the shore again. This bar was subsequently
