The Sakura-jima eruption of 1914, described by Koto, is 

 remarkable, not only for its great size and intensity, but also 

 for lateral eruptions which poured huge lava-flows into the sea, 

 and converted an island into a peninsula. These flows are 

 interpreted as due to horizontal satellitic injection of laccolites 

 into the flanks of the volcano, which gave rise to subordinate 

 lateral vents. 



Oinouye describes the varied phenomena of the eruption of 

 Usu in 19 10. The outbreak was preceded by numerous earth- 

 quakes and roaring noises. Then came explosions opening 

 V-shaped craterlets from which numberless red-hot bombs 

 were ejected. A remarkable feature was the extrusion of a 

 plug forming a new mountain. 



The great outflow of lava from Mauna Loa (Hawaii) from 

 May 19-31, 1916, brought to a close the eruptive period of 

 that volcano 19 14-16. There can be little doubt but that 

 Mauna Loa and the lava lake of Kilauea are connected. The 

 latter is now regarded as a decadent volcano of earlier origin, 

 acting as a gas pressure-gauge adjacent to, and partly buried 

 by, the younger and more vigorous Mauna Loa. 



Powers describes the intrusive bodies known to occur near 

 the summits of the Hawaiian basaltic volcanoes. These are 

 believed to represent the fillings of lava tubes. Other intrusive 

 masses have rather the form of volcanic necks. 



In his paper on Atlantis Schuchert combats the views of 

 Termier that the whole region of the Azores, Canaries, and 

 Cape Verde islands has recently been submerged beneath the 

 waters of the Atlantic. The subsidence of so great an area 

 (210,000 square miles) would have resulted in a lowering of 

 the eustatic strand-line of all oceans by 1 5 feet ; but there is 

 no sign of the terraces which should have been left along the 

 ocean margins.
