clay formation, which, being mixed up with salt water, is ejected by 

 means of gas, and dries into cones. 



The Littoral concrete is an impure loose-textured limestone, abound- 

 ing in shells, the majority, if not all, of which are identical with 

 those now common on the coast. At Jashk, on the Persian coast of 

 the Gulf of Oman, it is well developed, and forms a low cliff about 

 20 feet high. The chief geological interest attaching to this for- 

 mation is derived from the evidence it affords of recent elevation of 

 the land. 



Mr. W. King gives an interesting narrative of a traverse of parts 

 of the Kummummet and Hanamconda districts in the Nizam's 

 dominions; a moderately elevated tract to the westward of the 

 Godavery river. It is traversed by a path between Paluncha and 

 Narsimpet, along which route Mr. King made his observations, for 

 except around the few villages, up some side paths, or in dry water- 

 courses, it is at present almost impossible to see anything of the 

 country, owing to the prevalence of thin tree jungle and under- 

 growth. The formations met with included, in descending order, 

 the Kamthi sandstones, the Barakar sandstones, with Coal-seams 

 six and nine feet in thickness, and the Talchirs. The Coal-fields of 

 Pakhal talook and Pangadi Yagu are briefly described. 



Mr. W. T. Blanford furnishes a sketch of the geology of Orissa, a 

 province which borders the coast between Calcutta and Masulipatam. 

 He briefly describes the character of the formations met with, which 

 include Blown Sand, Alluvium, Laterite, Katak or Atgarh sand- 

 stones, Mahadeva? or Panchet sandstones and grits, Damuda sand- 

 stones, shales, and coal, Talchir sandstones, shales, silt, and boulder 

 bed, and Metamorphic or crystalline rocks. 



Mr. King describes a new Coal-field in the south-eastern part of 

 the Hydrabad (Deccan) territory. A small map is appended, showing 

 the general outline of the field and the rocks surrounding it. The 

 Coal-measures occupy about eight square miles in extent, but the 

 field requires further examination by borings before much can be 

 said about its richness. H. B. W. 



V. — Eeport of the Geological Survey of New Hampshire. 

 By C. H. Hitchcock, Ph.D. 8vo. (Nashua, 1871.) 



PEOFESSOE HITCHCOCK, the State Geologist, here presents 

 his report on the operations of the Geological Survey in New 

 Hampshire, during the year ending June 1st, 1871. 



The most laborious field of research has been the White Mountains, 

 comprising an almost unbroken forest, traversed only by the bridle 

 paths and roads required for the ascent of Mount Washington by 

 summer visitors. However, the Professor and his assistants, Mr. 

 J. H. Huntington and others, lived up in the mountains in extempore 

 camps, and visited the most inaccessible peaks and ravines, until all 

 had been explored. 



Very many speculations have been entertained respecting the 

 rocks, elevation and age of Mount Washington, and the associated
