On the Eruptions of the SoufrUre and Mont Pelee, 445 



Grenada in an examination of the lagoon at St. George's, but parti- 

 culars regarding these islands may be reserved till a fuller report 

 appears. 



DESCRIPTION OF THE PLATES. 



Plate 11. 



Mont Pelee eroit the West. 



Taken from the sea near Precheur, a village north of St. Pierre. This view shows 

 how the mountain'is cut up into deep ravines by the tropical rains. Part of the 

 summit is concealed by clouds, and the fissure from which the eruption was pro- 

 ceeding was apparently behind aud to the right of the small central peak. 



Plate 12. 



Mont Pelee eeom the South-west. 



This photograph was taken from the sea off the mouths of the Riviere Seche and 

 Riviere Blanche, which are about 2 miles north of St. Pierre. It shows the 

 rugged character of the mountain, the summit of which is concealed by clouds. The 

 slope in the foreground is the track of the avalanches which descended from the 

 triangular (light- coloured) fissure to the right of the central peak. 



Plate 13. 



Mont Pelee in Eruption. 



Taken from a sloop off St. Pierre on the afternoon of July 9. It shows the 

 " cauliflower " shapes assumed by the clouds of dust and steam as they drifted west- 

 ward out to sea. The lighter-coloured cloud to the east (or right) is the trade-wind 

 cloud which so constantly covered the summit. A small light-coloured cloud- 

 patch just below this, on the right-hand (eastern) side, indicates the fissure from 

 which the eruption chiefly proceeded. The eruptive "avalanche" of volcanic 

 material descended the slopes in the centre and rather to the left of the foreground. 

 St. Pierre is to the right, outside the picture.
