One of the popular three-days and two-nights trips is that taken each 

 year in the Columbia University summer field work. The party leaves 

 New York by day boat in the morning for Fishkill, visits Beacon Moun- 

 tain that afternoon, proceeds by train to Saratoga, where the first night 

 is spent. The next day it proceeds to Lake George and by boat as far as 

 Silver Bay, returning to Albany for the night. An early train the next 

 morning takes the party to Catskill for a study of the Little Mountains, 

 and New York is reached that evening. This trip always averages less 

 than $25 in cost, covering everything, and provides opportunity at least 

 to see most of the physiographic provinces of the east. In addition to 

 points of interest already noted for other trips, this one introduces the

Part of the folded Appalachian ridges are visible at the extreme left. The Great

Mohawk delta, the terraces of the Hudson, and the beautiful glacial 

 trough of Lake George (Fig. 23). Several papers by Kemp (70, 71), as 

 well as by other authors, deserve note. 



Boston Bay. — A splendid week-end adventure is a trip to Boston Bay 

 and Cape Cod. The night boat puts one in Boston next morning ready 

 for a day at Nahant or Nantasket Beach. The following two days may 

 be devoted to a study of Cape Cod. In this connection Johnson (48) on 

 Nantasket Beach and Davis (173) on Cape Cod may be cited. The stu- 

 dent would do well also to be acquainted with the writings of Shaler 

 (56), Emerson and Perry (34) on Narragansett Basin and Shaler's 

 (195) survey report on Cape Cod. The New England peneplane, Blue 

 Hill monadnock, the Boston Basin, drumlins, complex tombolos, beach
