12 CONNECTICUT GEOL. AND NAT. HIST. SURVEY [Bull. 



An effort has been made to obtain data concerning all the drilled 

 wells in the areas studied, and as many dug wells have been 

 examined as were deemed necessary to locate the position of the 

 water-table throughout the areas, and to supply a general 

 knowledge of the condition of dug wells, and the amount and 

 quality of water obtained from them." 



Cooperation with United States Geological Survey in 



other Work 



It is proper here to mention the fact that the work on the 

 water resources of the state is not the only work in which there 

 has been cooperation between the United States Geological 

 Survey and the State Survey of Connecticut. In the study of the 

 peat deposits of the state, a work of great importance, both 

 scientific and economic, in regard to which a bulletin is soon to 

 be published, the State Survey was greatly aided by the generous 

 cooperation of the United States Geological Survey, as is stated 

 more fully on page 19 of this report. In another instance, we 

 were able to render some service to the United States Geological 

 Survey. When Professor T. M. Dale was working on a bulletin 

 on the Granites of Connecticut for the United States Geological 

 Survey, he requested the Superintendent of the State Survey 

 to furnish an introductory chapter on the general geological 

 relations of the granites of the state. Such a chapter was accord- 

 ingly prepared by Professor H. E. Gregory, author of the chapter 

 relating to the crystalline rocks in Rice and Gregory's Manual 

 of the Geology of Connecticut (Bulletin 6 of the State Survey). 

 Bulletin 484 of the United States Geological Survey, on the 

 Granites of Connecticut, accordingly bears on its title-page the 

 words, " Prepared in cooperation with the Geological and 

 Natural History Survey of Connecticut." 



General Scope and Plan of the State Survey 



While it has been deemed best to devote the bulk of the 

 appropriation for the past two years to the cooperative work 

 on the water resources of the state, and to undertake no other 

 new work, it is not forgotten that the scope of the Survey, as 

 defined in the act of 1903 by which the Survey was established, 

 is much broader. That act proposed for the Survey two subjects 

 for investigation; viz., the geology of the state, and the natural 

 history, or botany and zoology, of the state. It has been pre- 

 sumed to be the intent of the law that the appropriation should 

 be divided with some approach to equality between geology and 

 biology. The law further specifies three aims with reference to 

 which the work should be prosecuted : — first, the purely scientific
