mountains favored the making of a strong record of glacial 

 border deposits at every halt. The drainage features especially 

 are very pronounced, and their value for determining the reces- 

 sional series is almost equal to the terminal deposits of deep 

 valleys with free drainage. 



The other series running north from Pittsfield passes by way 

 of Lanesboro and the Hancock valley to two lateral moraines on 

 the flank of the Taconic range west and northwest of Williams- 

 town, the last one being No; 15 as in the other series. Some of 

 the individual deposits of this series are not so strong as those 

 of the series through North Adams. 



One of the best series found is that which extends northward 

 in the Lebanon and Berlin valleys along the west side of the 

 Taconic range, but the study of these valleys is not yet com- 

 pleted. Beginning with the tongue at State Line as No. 9, the 

 series runs directly north past Lebanon Springs, Stephentown, 

 and Berlin to No. 17 near North Petersburg, the last four being 

 formed in a deep lake. Four more well-developed moraines lie 

 west of Hoosick Falls. No. 20 passes Johnsonville and enters 

 the city of Troy from the northeast, and No. 21 crosses the 

 Hoosic river three or four miles below Johnsonville, but it is not 

 known whether or not this last one touches the area of the 

 Taconic quadrangle. 



Going back now to the country bordering the east side of 

 Berkshire county, we find the Becket moraine (No. 6) extending 

 northeast to Plainfield. The splendid terminal moraine a few 

 miles to the south, near Cummington, seems to belong to No. 5. 

 From this point two series may be traced — one to the northwest 

 up the Westfield river to Savoy, and the other directly north 

 past Plainfield and down the east branch of the Chickley river 

 to the Deerfield at Zoar (No. 10). On account of its depth and 

 narrowness, the deposits in the Deerfield valley are unusually 

 strong and clear, and the series quite easily made out. From 

 Zoar the series may be followed past Monroe Bridge and Reads- 

 boro, whence one branch goes northwest past Hartwellville to 

 Woodford on the top of the Green mountain range, while another 

 longer series follows up the Deerfield past Davis Bridge, Sears-
