Postscript 



Since this article was in paged proof and ready for press the writer has 

 visited the Canadian localities east of Quays in company with Professor 

 Coleman and Mr. H. L. Kerr, of Toronto. Through the generous aid of 

 Mr. Kerr, in furnishing automobile transportation, a large territory was 

 covered during five days of active work, extending from Coburg northeast 

 to Belleville and north to Madoc and Queensboro. 



Many new localities were found, of both Iroquois and marine levels, 

 with excellent display of shore features. All the facts confirm the phil- 

 osophy of this paper. The interval between the latest Iroquois level and 

 the marine plane is 290 feet, the same as in New York. The figures in 

 the tabulation, plate 11, do not require serious change except for West 

 Huntingdon, which station Coleman has always regarded with doubt. 

 We there found a splendid display of Iroquois bars, having a vertical 

 range of 25 feet. The precise altitudes await information concerning the 

 datum points. These Iroquois shore features on the north end of the 

 hill, two miles northeast of West Huntingdon station, prove by their 

 strength and range a long life of the waters at this northern point and 

 indicate that the lake reached far northward from this point before the 

 lake was extinguished. The vertical range of the bars also indicates a 

 greater breadth of the wave of land uplift than was implied by the printed 

 figures and brings the lake history and land uplift in Canada into har- 

 mony with the facts in ISTew York. 



The figure 25 for splitting of beaches at Madoc should be changed to 

 30, and the figure 3 under West Huntingdon should be 25. The altitudes 

 of the two stations are subject to corresponding change.
