INTRODUCTION 



The Danbury region of Connecticut presents many features of 

 geographic and geologic interest. It may be regarded as a type 

 area, for the history of its streams and the effects of glaciation 

 are representative of those of the entire State. With this idea 

 in mind, the field work on which this study is based included a 

 traverse of each stream valley and an examination of minor 

 features, as well as a consideration of the broader regional 

 problems. Much detailed and local description, therefore, is in- 

 cluded in the text. 



The matter in the present bulletin formed the majn theme of 

 a thesis on " Drainage and Glaciation in the Central Housatonic 

 Basin " which was submitted in partial fulfillment of the require- 

 ments for the degree of doctor of philosophy at Yale University. 



The field work was done in 1907 and 1908 under the direction 

 of Professor Herbert E. Gregory. I am also indebted to the 

 late Professor Joseph Barrell and to Dr. Isaiah Bowman for 

 helpful cooperation in the preparation of the original thesis, 

 and to Dr. H. H. Robinson for assistance in preparing this 

 paper for publication.
