54 ICE RECESSION IN NEW ENGLAND 



5084-5200. — Continued 



5192, at locality 26, is relatively much thicker than at 

 point 28. 

 5201-5400. — In spite of several and considerable drainages the 

 curve from Greenfield (upper "12 Mass.") shows 

 rather good correspondence with that from North- 

 ampton (lower "12 Mass."). 



5201-5253, at localities 27 and 28, show very great fluctua- 

 tions, and some of them are sandy and attain 

 considerable thicknesses. The thick varves differ 

 greatly at the two localities, though these lie in 

 the same valley and only 600 yards apart (cf. 

 varves 5299~5303 and 5307-53*3) • 



5220-5222, at locality 26, and varve 5222, at localities 27 

 and 28, are drainage layers and consist of fine sand 

 and silt. Varve 5222, at localities 27 and 28, is 

 9^2 inches (24 cm.) thick. 



5245-5249, at locality 26, are sandy. At localities 27 and 

 28 they are sandy and very thick. 



5253, at locality 26, records a drainage. 



5270, 5272, 5277, 5281, 5282, and 5285, at all localities, are 

 sandy. 



5281, at locality 26, is 4 inches (10 cm.) thick and represents 

 a drainage. 



5299-5303 and 5307-5313, at locality 28, are thick and 

 consist of coarse sand; 5310 is 14 inches (35 cm.). 

 At locality 27 the same varves do not exceed i}4 

 inches (4 cm.) (see Fig. 19, and p. 69). 



5310 and 531 1, at locality 26, are each 2^3 inches (6 cm.) 

 thick and somewhat sandy. 



5316, at locality 28, measures 4>^ inches (11. 5 cm.). 



5397, at locality 26, is \]/& inches (10.5 cm.). 

 5401-5437. — Good. The agreement between the Greenfield 

 (upper "13 Mass.," PI. Ill) and Northampton 

 (lower "13 Mass.") curves is very fine.
