of the Ohittenango sheet, but aye not well indicated by the con- 

 tours. Thej have not been described, but will be briefly described 

 in the following pages, along with the later groups of channelsi 

 Jfth group. This group of channels lies on the north-facing slope 

 north of the village of Perryville, and along the north and north- 

 east slope of Craneon hill, between CMttenango and Cowaseloll^ 

 creeks. They form a series of interrupted scourways at differ- 

 ent levels, and are only suggested by the oontours on the adjoin- 

 ing lower corners of the Chittenango and Oneida sheets. 



5tli group. These strong channels are 3 miles south of Oneida, 

 village on the crest and north slope of West Stockbridge hill^ 

 between Cowaselon and Oneida creeks. They are fairly well' 

 indicated on the lower part of the Oneida sheet. 



6tli group. This very compact group of strong channels lies on 

 the north brow of Eaton hill, between Oneida and Sconondoa 

 creeks, 6 miles southeast of Oneida and 3 miles south of Vernon. 

 This is probably the most easterly group of high channels, judging 

 from the topography. However, the territory lying between here 

 and the Mohawk valley remains to be studied. 



Range in vertical distance. In each group the channels cover 

 a vertical distance of several hundred feet. The highest cutting 

 leading east must lie under the true plane of the lowest outlet to 

 sonthern flow. The original difference of level may, in some 

 cases, have been very small, and with the subsequent tilting of 

 the land it is possible that the later, east-leading channel might 

 now be even somewhat higher than the earlier one at the head 

 of the valley. The correlation of these east-leading channels with 

 the cols and south-leading channels on the divide is a subject for 

 future study. 



In the Eagle hill group the highest water course is over 1100 

 feet above tide, and the lower ones about 800 feet, all lying 

 within a horizontal distance of 1 mile. The Cranson hill group 

 ranges from 1200 down to 800 feet in 1^ miles. The West Stock- 

 bridge hill group has a greater range, from 1300 down to 700 feet 

 in something over a mile. The Eaton hill group ranges from 

 1200 down to 800 feet in less than a mile.
