waters. It is now utilized for a few miles by Murder Creek. The sag 

 stands but little above the old lake level, and probably was in part occupied 

 by a bay at the level of the lake. 



There is also a sag between the south and north ranges which would 

 have aiforded a line of discharge for glacial waters issuing from the north 

 range. It is now iitilized from near East Pembroke westward by a tribu- 

 tarv of Murder Creek, while Tonawauda Creek utilizes the part east of East 

 Pembroke. 



BATAVIA MORAINE. 

 DISTRIBUTION. 



The Batavia moraine forms the south member of a rather complex 

 series of moraines, drumlins, and eskers, which occupy the district imme- 

 diately south of Lake Ontario. The writer applied the name Lockport to 

 this south member some years ago,^ but upon further consideration it seems 

 preferable to substitute the name Bata^da. The western part is so vague 

 that some uncertainty is felt as to its continuation. The Batavia moraine, 

 from- the Grenesee River westward to the Tonawanda swamp in north- 

 western Grenesee County, lies just sou,th of the drumlin belt and has a 

 general course slightly north of west. From that swamp westward two 

 lines invite attention : one continues the course north of west to Lockport, 

 passing to the north side of the few drumlins which appear in that region; 

 the other leads south of west along or near the base of the Corniferous 

 escarpment toward Buifalo, keeping south of all the drumlins. The latter 

 course seems to have in its favor a relationship to the drumlins similar to 

 that found farther east. It, however, differs in being not even approxi- 

 mately at a right angle with the trend of the drumlins, but instead is nearlj^ 

 in line with them. So far as morainic features are concerned, there is very 

 little to favor this line, there being- only occasional slight ridging and a 

 few knolls and basins; and these, as already indicated, may be incident to 

 the retarding influence of the escarpment upon the ice movement rather 

 than marginal accumulations of a morainic character. 



While the uncertainty as to this line is great, it should perhaps be held 

 as a possible continuation of the ice margin, especially since the line toward 

 Lockport seems also open to question. Turning to the latter line we find
