The reader has now probably learned enough of this rising settlement,[29] and I have only to add that on the day following I returned to Bangalore, after having had a most pleasant and interesting time of it with my friends on the Kolar field. I next pass to a brief mention of the other auriferous tracts in Mysore, which were surveyed in 1887 by Mr. R. Bruce Foote, Superintendent of the Geological Survey of India, who, in connection with his investigations between February 2nd and May 7th of that year, travelled no less than 1,300 miles in Mysore in marching and field work. A full report of his work appears in the "Selections,"[30] and this is accompanied by a map in which Mr. Foote has sketched out the distribution of the auriferous rocks. In the "Selections" alluded to there, is also a "Report on the Auriferous Tracts in Mysore," by Mr. M. F. Lavelle, and "Notes on the Occurrence of Gold and other Minerals in Mysore," by Mr. Walter Marsh, Mining Engineer. But in the brief remarks I have to make I shall confine my attention to Mr. Foote's Report. Mr. Foote informs us that the chief gold-yielding rocks of Southern India belong to one great geological system, to which, from the rocks forming it occurring very largely in the Dharwar country, he two years previously gave the name of the Dharwar System, as he saw the necessity of separating them from the great Gneissic System, with which they had formerly been grouped. In his long tour in Mysore he found that every important auriferous tract visited lies within one or other of the areas of the Dharwar rocks, or forms an outlying patch of the same. These Dharwar rocks, it appears, are the auriferous series in Mysore, the ceded districts, and the Southern Maharatta country. Mr. Foote groups the auriferous rock series of Mysore into four groups--the central, west-central, western, and the eastern--the last group being formed by the Kolar gold field, which was not included in the tracts Mr. Foote was called upon to visit. He then gives a systematic account of his examination of the country, beginning with the central, and ending with the western group.
