Between Font-hill and Ebenezer (see map) there was an 

 extension of the Erie waters into the Ontario basin through a 

 strait, if such it can be called, as it was over thirty miles 

 across. The country in the Niagara district is a plain from

10 to 15 feet above Erie Lake. It is rendered somewhat 

 undulating by a few ridges of drift rarely rising 30 feet higher. 

 A rocky ridge of 20 or 30 feet above the lake is parallel with 

 the shores of Erie, a mile or two to the north of its outlet. 

 But the most notable ridge culminated in Drummondville, 

 near the falls, at 144 feet above the lake level. This is a small 

 knob at the end of a long spit which is the historic Lundy 

 Lane. The surface of this strand is 30 feet below the knob 

 just noticed. This ridge formed a spit which was the first 

 barrier that appeared between the Erie and Ontario basins, 

 and here the waters last lingered before they subsided within 

 the lower basin. The knob at Drummondville is not an undu- 

 lation of the Lundy shore, although it is made up of beach- 

 material, but belonged to a higher level. Whether a fragment 

 of an older strand or not, still equivalent remains of deserted 

 water-lines are found at Font-hill, Akron and elsewhere. 



The crest of the Lundy beach is from 100 to 200 feet wide 

 and forms a conspicuous sand and gravel ridge of more than 

 double this width at the base, to which it slopes — 20 or 30 

 feet below, and bounds an extensive plain on both sides, as it
