stratified débris of all formations adjacent northwards, with some 
stratification of the surface of an irregular kind. A peculiar fea- 
ture of the range is the presence of large holes and sinks, some of 
which are full of water. From these holes the range is called the 
Kettle Moraine. Its distribution is alike regardless of the geo- 
logical and topographical features of the country, excepting in its 
parallelism to the southern border of the Great Lakes. Professor 
Chamberlin regards it as a terminal moraine which marks a 
period in the history of the glaciers which are supposed to have 
once filled the depressions now occupied by the Great Lakes.

GEOGRAPHY AND TRAVELS.! 
Tue Amazon.—In the September number of the aS ce 
mention was made of the survey of the Amazon and 
rivers, undertaken by the U.S. corvette Azterprise, Comandet 
Selfridge. This vessel arrived at New York on the 25th of Sep- 
tember last, and we learn from the New York Hera/d of the suc- 
cessful accomplishment of her mission. At Serpa, near the 
mouth of the Madeira they found the Amazon a mile in width 
and sixty feet deep. The Madcira is here about two miles wide, 
and its principal channel has a depth of from ninety to sixty feet, 
according to the season of the year. From near its mouth to the 
falls its banks are high and well marked. The steamer entered 
the Madeira on the 17th of June, and advanced without difficulty 
at the rate of twenty-five miles a day, stopping at night, until the’ 
21st, when near the island of Araras the pilots reported rocks 
and shoals. Although careful investigation proved that no rocks 
were there, and five fathoms of water was found, it was not 
deemed advisable for the ship to cross, owing to the reports of
