were staying at the camp, lake shore, considerable attention 

 was given to the lower portion of the glacial drift subjected to 

 tidal or stormy influence of the water, and also to a small 

 ravine some few hundred yards to the west of the camp, 

 where an exposure occurs below the little that remains of the 

 primeval forest. The waters of Ivake Ontario in the wildest 

 storm penetrates only a few yards at the mouth of this creek, 

 and when you find fossiliferous shingle embedded in the 

 glacial clay there, it can readily be seen that land ice can 

 alone account for the glacial deposit. The writer believes if 

 his old friend and master in Geological matters, the late Sir 

 W. Dawson, had studied the interior of this continent as 

 carefully as its western extremity, he might have modified 

 views not generally accepted either in Canada or the States. 



As I stated in our last year's proceedings, the first 

 discovery of a true Trenton fossil in the glacial drift here was 

 made by our former president, the late A. E. Walker, below 

 the Ancient I^ake Iroquois Beach near the canal. It proved 

 to be the tail shield of Asaphus Platycephalus. Our friend 

 also extracted, on a different occasion at the same place, a 

 small slab of Utica shale, containing a fragment of Professor 

 E. Chapman's Trilobite, Asaphus Canadensis. 



The writer noticed, on his arrival at Winona Camp some 

 years ago, there was a considerable amount of shingle 

 embedded in the lower part of the glacial clay. The material, 

 on extraction, was found to be scratced and polished. Under 

 the hammer it proved exceedingly hard. The first ones 

 examined were unfossiliferous, and further examination was 

 only resumed during the last three summers. It is natural to 

 suppose the glacial markings would disappear from shingle 

 washed out and exposed to the action of the water and a 

 sandy shore. In general, the shore shingle also is difficult to 

 break up. Exception may be made to rocks derived 

 apparently from an upper portion of the Hudson River series. 

 This very circumstance led to a systematic enquiry as to 

 whether any softer shingle than I had previously extracted 

 existed in " the glacial clay," AH doubt on a point formerly
