Of course such objects as fountains and national 

 memorials of various kinds may be artistic in character 

 and suitable adornments for a public park. But they should 

 be few in number and have suitable settings. 



POSSIBLE RELATION BETWEEN SUNSPOT MINIMA 



and VOLCANIC ERUPTIONS.

During the past three months the world has been startled 

 by a series of volcanic and seismic phenomena, which, in 

 point of extent and violence, are almost unparalleled. 

 Within a few months we have heard of a great earthquake 

 at Cheviot, in New Zealand, synchronous with a violent 

 volcanic eruption in the Kermadec Islands. This was suc- 

 ceeded by a violent earthquake in Transcaucasia that ruined 

 numerous towns. Then came the West Indian earthquakes 

 accompanied, or rather followed by the eruptions of Mount 

 Pelee, La Soufriere and Mount Tacoma, and synchronously 

 great earthquakes devastated ten cities in Guatemala. 

 Since then we have heard of a succession of rumblings in 

 the Auvergne district of France, an area spotted with 

 extinct volcanoes ; a serious earthquake at Corfu, another 

 near Paris ; and lastly we hear that Mount Redoubt in 

 Alaska is in violent eruption, and that poisonous gases are 

 issuing from Mount Traboclietto, an extinct volcano 

 between Genoa and Nice.
