isbury, Mr. Frank Leverett, and Mr. Buell, who all have spec- 
ially studied the drift around Madison, lead me to think it 
more frequent there than in New Hampshire. Massachusetts. 
and New York, where also drumlins are magnificently devel- 
oped, among- which, however, the Madison type certainly is 
very rare. 
NOTES ON THE GEOLOGYOF THE ROCKY MOUN- 
TAINS BETWEEN THE SASKATCHEWAN 
AND THE ATHABASCA. 
By A. P. Coleman, School of Practical Science. Toronto, Can. 
During the summers of 1892 and 1898 some explorations 
were made in the Rockies between the headwaters of the Sas- 
katchewan and the Athabasca: The region lies between two 
fairly well known passes, the Howse pass, leading from the 
Saskatchewan to the Columbia, and the Athabasca pass, fol- 
lowing up Whirlpool river from its junction with the Athabasca 
and following down Wood river, a tributary of the Columbia. 
The tract of mountains ljdng between the two passes, though 
including some of the grandest mountain scenery in North 
America, has been almost wholly neglected by scientific ob- 
servers, and the maps hitherto published represent it very in- 
correctly. 
In 1892 the expedition consisted of .Mr. Stewart, of Toronto, 
Dr. Laird, of Winnipeg, Mr. Pruyn, Mi-. L. Q. Coleman, of 
Morlev. Alberta, and the writer: with two Stony Indians as 
guides. In 1893 the party was limited to Mr. Stewart. Mr. 
L. (^. Coleman, and the writer. Guides were dispensed with. 
having been found useless beyond theirown hunting ground-. 
A white man. Frank Sibbald, was employed as packer, and 
proved very efficient. 
The object of the expeditions was mainly topographical, to 
explore an interesting unexplored region and especially to de- 
termine the hight of Mt. Brown, reputed the highest mountain 
in Canada. The topographical results and a map showing 
several new lake- and rivers, as well as the general mountain 
features, will he published elsewhere. It may lie mentioned, 
however, that Mt. Brown was found t<> be only '.umiu feet in 
hight, instead of nearly 16,000, as generally stated. There
