States Geological Survey in the usual form of their publications, 

 and at the expense of the United States. The contract, however, 

 gives to us the right to republish any part of these results in the 

 series of Bulletins of the State Geological and Natural History 

 Survey; provided, only, that, in any form of publication of a 

 special Connecticut edition, credit shall be given to the United 

 States Geological Survey for their share in the work. 



Work on Water Resources during the Past Two Years 



The total appropriation of four thousand dollars (two thou- 

 sand from the United States and two thousand from the State 

 of Connecticut) has of course sufficed only for a very modest 

 beginning of the survey of our water resources. It has been 

 deemed best to use the whole amount in a study of underground 

 waters in certain selected areas. The field work has been done, 

 under the direction of Professor Gregory, by Arthur J. Ellis, 

 M.A., Junior Geologist, U. S. Geological Survey. The following 

 account of his work is quoted from a letter of Mr. Ellis to the 

 Superintendent of the State Survey. 



" Under the direction of Prof. H. E. Gregory, I have studied 

 the water supplies, with especial attention to underground waters, 

 in selected areas in Connecticut, which represent the typical 

 geologic conditions of the state. These areas are : 



" i. The Hartford area, including the towns of Hartford, 

 West Hartford, Newington, Wethersfield, Manchester, East 

 Hartford, South Windsor, East Windsor, Windsor, and Bloom- 

 field. 



" 2. The Stamford area, including Stamford and Greenwich. 



" 3. The Canaan-Salisbury area, including Canaan, North 

 Canaan, and Salisbury. 



" 4. The Willimantic area, including Windham and Franklin. 



" 5. The Saybrook area, including Saybrook, Essex, West- 

 brook, and Old Lyme. 



" In each of these areas the towns have been studied as units, 

 and the results are to be given on the same basis, but grouped with 

 reference to the areas. A map of each town has been prepared, 

 upon which are shown data relating to underground waters, and 

 contour lines representing the position of ground water with 

 reference to the land surface. In the Hartford area the rock 

 surface is also shown by contour lines. In all except the Hartford 

 area, these maps will show the distribution of timber and tillage, 

 and of rock outcrops and Glacial drift. 



" Field assays have been made of several hundred samples of 

 water taken from springs, dug wells, drilled wells, and brooks.
