175- Julien, A. A. 



On the geological action of the humus acids. 

 Am. Assoc. Adv. Sci., Proc, xxviii, 311-410, map, 1880. 

 Discussion of the decomposition taking place in rocks, including the 

 Triassic sandstones of Connecticut, and the source of the iron oxide. 



176. Kemp, J. F. 



The great quartz vein of Lantern hill, Mystic, Con- 

 necticut, and its decomposition. 



New York Acad. Sci., Trans., xv, 189, 1896. 



Vein 400 feet wide, 1,200 feet long; composed almost entirely of hard, 

 milky white quartz, which, however, is very crumbly, due to effects of 

 faulting or crushing rather than to corroding alkaline solution. The 

 rock contains 98-99.4% SiO. 



(For a different explanation of Lantern hill, see Rice and Gregory, 

 243a. — Ed.) 



177. Kemp, J. F. 



Granites of southern Rhode Island and Connecticut. 



Geol. Soc. America, Bull., x, 361-682, 7 pis., 1899. Ab- 

 stract: Am. GeoL, xxiii, 105-106, 1899; Science, ix, 140- 

 141, 1899. 



Occurrence and petrography of granites along the shore from Rhode 



Island to New Haven, particularly at Westerly and Stony Creek. 



Granites are intrusives of post-Cambrian age; pegmatites and aplites 



are described. Analyses of granite from Westerly, Millstone point, 

 Stony Creek. 



178. Killebrew, J. B. 



Report on the culture and curing of tobacco in the 

 United States. 



Census of U. S., loth Rept., iii, 583-950, 1883. 



The soil of the Connecticut and Housatonic valleys is suitable for 

 tobacco.*' Terraces of the Champlain period and flood-plain deposits are 

 best adapted. Character of soil derived from porphyry, micaceous rocks, 

 granite, chlorite slate, sandstone, and trap is discussed. 



179. Kimball, H. H. 



Ice caves and frozen wells as meteorological phe- 

 nomena. 



Mon. Weath. Rev., 366-371, August, 1901. 



Ice deposits found in summer in ravines and gorges at Meriden, 

 Northfield, and Salisbury. 



180. Knowlton, F. H. 



Report on fossil wood from the Newark formation of 

 South Britain, Connecticut. 

 U. S. Geol. Surv., 21st Ann. Rept., pt. iii, 161-162, 1901. 



Microscopical description of more or less silicified wood, of the 

 species Araucarioxylon virginianum Knowlton, found in the Newark 

 formations of South Britain. The Connecticut material is identical 

 with species from Virginia and North Carolina.
