the island by southwest storms off Lake Ontario. The portion 

 of the bar that is above water level has a peculiar curved form, 

 due to the many complex modifications which such a bar may 

 undergo under the influence of minor storms. Some of these 

 are well shown near the free end of that portion of the bar 

 which rises above water level. On the south side of the free 

 end we find two large, well-developed, south-pointing cusps, 

 bounded by curves which are concave lakeward. These cusps 

 seem to owe this form to the action of waves advancing from 

 the southeast and the southwest at different times. 



8. Calf Island loop bar. — Although not in any way associated 

 with the Bay of Quinte, it seems desirable to include in these 

 descriptions a reference to the loop bar off the east end of Calf 

 Island. The island lies about four miles northwest of Stony 

 Point, and half a mile to the west of Stony Island. Storm waves 

 blowing down the lake naturally divide at the island and pass 

 on either side of it. Coarse gravel derived from the limestone 

 rock, by which the main island is underlaid, has been piled in 

 two high ridges, one leading off from either side of the island. 

 The two unite in a rather sharp. point about 350 yards from the 

 east end of the rocky part of the island. The crests of the bars 

 are about 9 feet above water level, and between them is a deep, 

 narrow pond. The south bar is about 60 feet wide, and has 

 equal slopes on either side; the north bar is a little wider and 

 more irregular. 



Similar forms are to be looked for off the northeast ends of 

 several of the other rocky islands in this part of the lake. Off 

 the east end of Grenadier Island two long flying spits have 

 formed, inclosing between them a shallow bay known as Basin 

 Harbor. This bay is gradually filling up. The free ends of the 

 two spits are curving toward each other, and, given time enough, 

 we would expect them to unite. In the meantime, the inclosed 

 basin will be partly filled by sand either washed in by the waves 

 or blown in from the bars. The outer slope of the bars will still 

 have the steep gradients of such forms; their height will depend 

 upon the depth of the adjacent water. In time there will thus 

 be formed off Grenadier Island a huge terrace, with running
