3. Sixth Biennial Report of the Commissioners of the State 

 Geological and Natural History Survey of Connecticut for 

 1913-U. Bulletin No. 25, 1915. Pp. 24.— Since its organiza- 

 tion in 1903, the Connecticut Survey has received an annual 

 appropriation of $1500. With this insignificant sum at his dis- 

 posal the Director has secured remarkable results. Twenty-one 

 bulletins have been published, covering the fields of geology, zool- 

 ogy and botany, three bulletins are in press, and five more are 

 represented by completed manuscripts. According to a coopera- 

 tive agreement with the United States Geological Survey, effec- 

 tive in 1913, $2000 per year has been allotted to investigation of 

 water resources and plans for the next biennial report involve 

 the continuation of this work. h. e. g.

 and a mineralogical collection suitable for museums may be 

 obtained within the borders of the state. The report by Brown 

 and Ehrenfield is a sort of elementary text-book which should 

 find a place in schools as well as in the libraries of the miner and 

 prospector. h. e. g.
