Origin Of The Gondwana Rocks.--From the evidence afforded by the fossils, and the lithological characters of the rocks, it is probable that the Gondwana strata were deposited in a series of river valleys not unlike those which constitute the Indo-Gangetic plains at the present day. The rivers were generally sluggish in their movements and occasionally may have formed lakes. Areas Of Gondwana Rocks.--The following Table of the areas of the Indian coal-measures and associated younger rocks which may conceal coal-measures has been drawn up by my colleague, Mr. Hughes: --Godaveri and affluents Sone Sirguja and Orissa, &c. Assam Narbuda and affluents. Damuda Rajmahal area... Unsurveyed, &c.. 11, ooo square miles. 8,000 4,500 3,000 3,50o 2,000 300 2,700 35,000 For the sake of comparison other countries with greater areas are enumerated: --United States..... 500,000 square miles. China 400,000 Australia 240,000 India comes next or fourth on the list. Although I believe Mr. Hughes' estimates require some modifications in detail, still the total cannot be far from correct, and 30,000 square miles might, I think, perhaps be safely adopted as a minimum.
