teeth of Garcharodon rectus somewhat numerous, while inver- 
tebrates have been collected in Ventura county in great abund- 
ance. It is a rich field for the geologist, and has an important 
bearing on the physical history of California, and of the Pacific 
slope. 
Mr. R. G. McConnell, of the Canadian geological survey, 
has returned from his inspection of the region between the 
Peace and Athabasca rivers. He commenced about 300 miles 
north. of Calgary and extended his operations for some 300 
miles further north to the vicinity of Vermilion. The region 
embraces an area of 30,000 or 40,000 square miles. Little of 
this tract was ever explored before by wdiite men. A great 
deal of it is good farming land, but swamps abound and make 
it unfit for settlement. The trees are principally spruce and 
poplar. Speaking of the deposits of oil reported to be there, Mr. 
McConnell said he certainly found quantities of tar, indicating 
the presence of oil, but just in wbat quantities it existed he 
was not prepared to say before making his reports. 
Prof. Arthur Winslow, state geologist of Missouri, has 
entered upon the active prosecution of the survey. His head- 
quarters will be at Jeff'erson City. He has made the following 
selections for assistants: James D.Robertson, AVashington 
University, St. Louis, assistant geologist; Dr. Hambach, 
Washington University, St. Louis, assistant paleontologist; 
Elston Lonsdale, Columbia, aid to the palaeontologist; Leo 
Gluck, Lamonte, aid and mining engineer ; Prof. Walter P. 
Jenney, of the U. S.Geol. Survey has been assigned work in 
surveying the lead and zinc deposits in co-operation with Prof. 
Robertson. 
Artesian water from the Archean. Operations of the 
Minnesota Iron Company at Tower, Minn., in sinking diamond 
drills into the Keewatin rocks to determine the position and 
extent of the ore deposits, have resulted in producing artesian 
or flowing wells in several instances. The water is pure and 
cold, and flows at the rate of three gallons per minute from 
the depth sometimes of over five hundred feet in the oblique 
direction of the drill, or about two hundred and fifty feet per- 
pendicular depth. It is found to be useful and valuable at 
the mines. 
Professor Daniel Kirkwood, for many years a professor 
of astronomy in the Indiana State University at Bloomingtori, 
has removed his residence to near Riverside, in southern Cali- 
fornia. 
Dr. Leo Lesquereux, the eminent pal.eobotanist, died 
at Columbus, 0., Friday, October 25th, in his eighty-third 
year. In a subsequent number of the Geologist will be given 
an appropriate sketch of his life and work.
