Middle Island is a verdure covejed- lime-stone ledge some 

 twenty rods in width by ninety or more rods long, the long 

 axis lying nearly east and west, thus lying directly athwart 

 the south point of Pelee Island, and some four miles distant. 

 The.re is a border of trees of considerable size and a peach 

 orchard occupies ' the interior. A light-house stands at its 

 eastern end. The only inhabitants are the light keepers. Here, 

 in late August and early September, warblers of many species 

 were swarming. In 1908 the sand ridge which has been built 

 up at the western end contained many nests of Common Tern. 

 In other years no te.rns' nests were found here. 



Kelley s Island forms the first stepping stone for the north- 

 ward moving birds, being separated from the headland of 

 Marblehead by a strait of water about three miles wide. Like 

 Put-in-Ray it is a iiiass of limestone rising out of the lake. 

 Extensive quarr^qng (vf the limestone has been in progress for 

 years. There is a fringe of trees everywhere except on the 

 northern exposure, while the western third contains an exten- 

 sive ]ieach orchard with bordering woods of considerable ex- 

 tent. The highest point of this island is seventy-five feet above 

 the lake level. It is about two miles from Middle Island. This 

 island is a considerable fragment of the mainland, which 

 ]\Iosely says was once clearly a part of the mainland promo- 

 tory, with probably low or even marshy ground connecting it 

 with Marblehead. Indeed, there are historical accounts of 

 crossing by Indians and others, with only narrow channels to 

 swim. 



It would therefore appear that at some time not so far 

 distant these islands were elevated limestone masses of a 

 nearly continuous land barrier connecting Point Pelee with 

 Marblehead. Doubtless also the P>ass Island group with 

 the adjacent smaller islands, at the same time were con- 

 nected with Catawba Island. The Hen and Three Chickens, 

 East Sister and North Harbor seem to form another group 

 of the same nature, with a possible connection with the
