l8 CONNECTICUT GEOL. AND NAT. HISTORY SURVEY [Bull. 



generous cooperation of the United States Geological Survey. 

 During the summer of 1907 the field work of the investigation 

 was substantially accomplished. The localities of all the impor- 

 tant peat bogs of the state were visited, the area of those bogs 

 was noted, their depth was determined by a sounding apparatus, 

 and samples for analysis were collected from various depths. 

 This work was accomplished by Messrs. E. C. Miller, A.B., 

 and T. T. Giffen, A.B., of Yale University. Professor C. A. 

 Davis of the United States Bureau of Mines, who was employed 

 by the United States Geological Survey in the summer of 1907 for 

 a reconnoissance of the peat deposits of the Atlantic border of the 

 country from Maine to Florida, was permitted by the courtesy of 

 the United States Geological Survey to spend a few days in 

 Connecticut at the beginning of the season of field work. He 

 was able, therefore, to give Messrs. Miller and Giffen the neces- 

 sary instruction in regard to methods of work. The bulletin 

 which is now nearly ready for publication, will contain a general 

 paper on the scientific and economic relations of peat, by Professor 

 Davis, who has made himself eminently an authority on the sub- 

 ject. It will also contain a digest of the notes of Messrs. Miller 

 and Giffen in regard to their field work. A selection of samples 

 collected by Messrs. Miller and Giffen have been analyzed in the 

 laboratory of the United States Geological Survey, and reports 

 of those analyses will be included in the bulletin. The State 

 Survey is very greatly indebted to the liberality of the United 

 States Geological Survey for the all-important assistance of Pro- 

 fessor Davis at the beginning of the investigation, and for the 

 analyses made in the laboratory of the United States Geological 

 Survey. The attention which has recently been given to the 

 scientific and economic relations of peat has brought into notice 

 the valuable work on peat from the chemical standpoint done 

 many years ago by Professor S. W. Johnson, the pioneer in agri- 

 cultural chemistry in this country. Professor Johnson's book is 

 out of print, and his work on peat had been almost forgotten. 

 The forthcoming bulletin will render his important work once 

 more accessible by the republication of the important parts of his 

 book, edited and revised by his friend and pupil, Dr. E. H. 

 Jenkins, Director of the Connecticut Agricultural Experiment 

 Station.
