Gilgit (a tributary of the Indus), earring the drainage of a line of 

 lofty peaks and their southern spurs, which curve round from Ralci- 

 pushi on the west to Emerald Peak on the east. From below Sinakar, 

 in the lower part of the Bagrot Valley, comes a fbornblende schist 

 (the general strike being nearly E.N.E., dip 55 northerly) and a 

 fdiorite. Hence to a fork in the valley near the foot of the Bagrot 

 glacier, the specimens represent apparently fcrushed gneiss, and 

 diorites of more than one kind. One of these is said to extend far 

 along the valley ; others are common in the debris. Some strikes are 

 recorded to easterly or east-north-easterly points, but the dips vary. 

 The Bagrot glacier issues from a loop of peaks, and Mr. Con way re- 

 marks that the mountains on the western side of the glacier as far 

 as Rakipushi consist of hornblende rocks, like those of the Bagrot 

 Valley. From the ridge he collected a fcrushed gneiss, and from the 

 Kamar nala beyond a crashed fquartzose mica schist. On the 

 eastern side of the glacier were collected a calcareous fsillimanite 

 schist and a fhornblende schist, the latter being pretty certainly a 

 crushed doleritic rock, and not unlike some of the " griiner schiefer " 

 of the Alps. From the glacier come a diorite, common in the left 

 moraine, and a crushed mica schist. Passing up the eastern fork, 

 Mr. Conway collected a fhornblende schist (or pressure- modified 

 diorite), a fnaica diorite, and some fsericite schists, before reaching 

 the foot of the Burchi glacier which, descending from the north, joins 

 the yet larger Gargo glacier. The specimens from near the former 

 represent a crushed tcalc-mica schist (in situ on the spur between 

 the two glaciers) and (from the left moraine). a diorite, an impure 

 limestone, and a phyllite, so that there must be here an infold of 

 comparatively unaltered rock. From the other glacier a crushed 

 factinolitic schist occurs on the left bank of the valley beyond Gargo ; 

 yet further up on this side comes a fgneiss (crushed). The glacier 

 was now crossed again to the slopes beneath Emerald Peak, on the 

 ascent of which fsericite schist and fchlorite schist were obtained. 

 The right moraine of the Gargo glacier furnishes sericite schists, the 

 left moraine or left side, piedmonite schists, chlorite schist, diorite, 

 hornblende schist or schistose diorite, calc-mica schist, and phyllite; 

 from the more disturbed material is another diorite. Piedmontite 

 schist also comes from a boulder farther down the valley on the left 

 side. The exact locality where this interesting rock occurs in situ is 

 not determined, but it is clearly somewhere in the buttresses of the 

 Gargo Peaks. These are part of a huge spur which extends from 

 the Emerald Peak to Dubanni. The strikes along the Gargo Valley 

 from the fork are generally between 5 S. of E. to 7 S. of E.S.E., the 

 dips on the south side of the valley and on a peak east of Gargo, are 

 northward (from 40 to 80) or vertical ; on the north side of the 

 valley they are southward 60. On the hill above the icefall, how-
