Summary of Papers. 



Dr. Hovey gave a summary account of the results obtained 

 on two expeditions undertaken by him for the American Mu- 

 seum of Natural History in 1902 and 1903, for the study of the 

 volcanic eruptions of the Soufriere, which began in May, 1902. 

 Particular attention was devoted to the heavy coating of vol- 

 canic ash deposited upon the northern portion of the island of 

 St. Vincent and the ash-filling of the gorges of the Wallibou 

 and Rabaka Dry Rivers, the devastation wrought in the forests 

 and on the plantations within a radius of about five miles from 

 the crater, the phenomena of primary eruptions observed in 

 the crater and of secondary eruptions observed in the Wallibou 

 and Rabaka ash-beds. The nature of the explodmg eruption 

 cloud was discussed, and -it was shown how the heavily dust- 

 laden steam cloud kept close to the surface of the ground under 

 the influence of gravity, while its initial velocity was furnished by 

 the horizontal component of the explosion. 



About eighty lantern slides were used in illustrating the 

 speaker's remarks.
