at Bombay, Agra, Calcutta and Kodaikanal. This shock was felt at such distant places as Kabul, Dehra Dun, Simla, Multan, Dera Ismail Khan and Roorkee.

The frequency of aftershocks of the Quetta earthquake of May 1935 appears to have considerably diminished, but several sharp shocks were felt during the year in the Assam seismic area, of which the shocks of 16th January at about 18.45 hours and of 21st March at 21:45 hours I.

METEORITES.

35. Mr. J. B. Auden was informed by the Tahsildar of Skardu, in Kashmir, that a meteorite fell at or near Arundu, in the northwest corner of sheet 43 M, in September, 1936.

In the Calcutta edition of the Statesman of the 12th November, 1937, it was reported that a number of large stones had fallen from the sky and had crushed to death two men and a woman near their hut near Jhansi in the United Provinces. The phenomenon was supposed to have occurred in a storm that was preceded by rumbling noises and a blinding light which shot across the sky. Reference to the District Magistrate of Jhansi and the Political Agent, Bundelkhand Agency elicited the information that no fall of meteorites had been reported in the district of Jhansi, or in Datia and Orchha States.

There seems little doubt that a meteorite fell near Mabwe-Khoywa village in the Karenni State of Kyetbogyi, about 120 miles east of Toungoo in Burma at about 10.45 P.M. on the 17th September, 1937. A Karen 'cultivator, Htisalay, while sleeping at his house, heard a noise like the explosion of a cannon in the sky and saw 'a brilliant ball of fire fall through the roof at the back of his house'. Villagers who saw the occurrence were awestruck. Some went to Htisalay's house and extinguished a fire that had been started. Next day Htisalay is said to have found a meteorite in a deep hole, and this has since entered the possession of Mr. Thompson Durmay of Toungoo. It is said to weigh about 4.9 lbs. So far it has not been examined by this Department. However, Mr. Durmay sent for examination and return a small specimen of another so-called meteorite which was supposed to have been found by Saw Derthamoo of Lapache village, Karenni State. This proved to be a schistose granite.

ECONOMIC ENQUIRIES.

Bauxite. 36. Primary laterite resulting from the alteration of the Deccan trap in situ is found extensively in north-west Jashpur and in the

Khuria highlands, forming cappings on the Jashpur State, Eastern flat-topped

hills locally known pats. States Agency.

These laterite cappings locally contain segregations of bauxite. In the course of his work in Jashpur State, Dr. Dey found two areas of laterite where the segregations of bauxite are rich enough to attract attention. One is located on the pat north-west of Patia (22° 58' : 84° 1'). Here bauxite occurs scattered blocks and segregated patches in the laterite and is found all along the pat in its northward extension. There is also some detrital bauxite west of the village. Owing to its mode of occurrence it is difficult to estimate the total quantity of ore available near Patia, but Dr. Dey considers that there would no difficulty in obtaining 25,000 tons, or possibly much more, from this area.

marble and dolomite deposits of Ghundai Marble, Mardan district Tarako, a hill forming part of the boundary and Swat, N.-W. F. P.

between the Swabi tahsil of the Mardan district and the Buner tract of Swat. The results of Dr. Coulson's work have been incorporated in a paper published in Part 2 of Volume 72 of the Records of the Geological Survey of India ; pp. 227-234, (1937). He concludes that perhaps the largest deposits of pure white statuary marble in the Frontier Province will be found in the Gundai Tarako, but adds that careful selection of sites for development should be made, taking into consideration the type of stone required. Probably the best sites for development will be found in the neighbourhood of the main peak of the ridge.

Dr. Coulson's paper contains numerous analyses of samples from different parts of the ridge and the excellent quality of the stone available is well shown.

Alteration and weathering of the felsitic rock of Drug has ccasionally resulted in soft kaolinic matter. Often this is fairly free from grit and when kneaded with water forms a plastic mass, with fusibility just below 1,400°C. The heated brick (1,400°) suffers contraction and becomes uniformly glassy without losing shape or developing cracks. The colour of the unburnt brick is dull white, while that of the burnt brick is dark greenish grey. Noteworthy occurrences have been recorded in the river basin between Jungera Kalan (20° 42' : 80° 58') and Bhandaritola (20° 42' ; 80° 59') in the Sanjari tahsil,
