    them on the 29th of September, after having traced the Indus down to Demchok in Ladak. From Demchok he crossed from the basin of the Indus to that of the Sutlej by a very high pass, and carried a route-survey down to Totling. From Totling the second and third Pundits were sent down the Sutlej to Shipki, tracing the river as closely as they could. From Shipki they carried a route- survey in a southerly direction, crossing the Himalayas by a high pass, and descending to Killing on the upper course of the Ganges. The Pundit himself returned from Totling to Badrinath by nearly the same route as he advanced by, only making one small variation. Ultimately the second and third Pundits rejoined the first, and they all made their way down into British territory by the beginning of November. The geographical results of the exploration can be seen at a glance from the accompanying map. They account for the geo- graphy of about 18,000 square miles, founded on 850 miles of route- survey, with 80 heights. The routes are checked by 190 latitude observations taken at 75 different points. The course of the Sutlej Eiver has been roughly traced from Totling down to Shipki, on the border of British territory. Hitherto there has been no survey of any kind of this portion; and the route, though only actually touching the river for a short dis- tance, was carried near enough to it to enable the Pundits to lay down its probable course very closely. The position of Gartok, as determined by the two routes of the last expedition, has been con- firmed by a third route carried up from Badrinath. The mean of three gives a very good longitude of Gartok,* as has been proved by the further route-survey carried from Gartok to Demchok, which latter had been previously fixed by the regular survey operations in Ladak. The longitude by the route-survey only differing from that of the regular survey by 21 minutes—a very satisfactory result from a route-survey f traversing 160 miles direct over such a very rough tract of mountains.
