DISCUSSION AND CORRESPONDENCE. 



THE UNION AND RIVERSDALE FORMATIONS IN 

 NOVA SCOTIA. 



To THE Editor of Science: In your issue 

 of January 17, 1902, Vol. 15, No. 368, on page 

 90, the title and abstract of my second paper 

 read before the Geological Society of America, 

 held in Rochester, are given, which require a 



slight emendation. The following exact title 

 and brief abstract are herewith submitted: 



Title : ' The Meso-Carbonif erous Age of 

 the Union and Eiversdale formations in Nova 

 Scotia.' 



Abstract: From internal paleontological 

 evidence the Union and Riversdale formations 

 are clearly Middle or Meso-Carboniferous. 

 The insect, reptilian, lamellibranchiate, crus- 

 taceous and other associated faunas, as well as 

 the floras entombed in the Riversdale shales 

 and sandstones, according to R. Kidston, of 

 Stirling, Scotland; David White, of the U. S. 

 National Museum, Washington; Dr. Wheel- 

 ton- Flind, of Stoke-upon-Trent, Eng. ; S. H. 

 Scudder, of Cambridge; Henry Woodward, of 

 the British Museum, London, Eng., indicate 

 a typical Carboniferous horizon, which, when 

 compared with similar faunas and floras else- 

 where, lead one to state that a Meso-Oar- 

 boniferous age is here represented. 



In Cumberland County, Upper Carbonifer- 

 ous limestone beds, formerly classed as Lower 

 Carboniferous, are thrust over siliceous shales 

 and sandstones, etc., presumably of Meso- 

 Carboniferous age, formerly classed as Devo- 

 nian and referred to the 'rocks of Union' or 

 Union formation. In Pictou and Antigonish 

 Counties, Lower Carboniferous strata rest 

 uncomformably upon the upturned Eo-Devo- 

 nian, with which the Union and Riversdale 

 formations were formerly correlated by stra- 

 tigraphers.

HIGH WATER IN THE LAKES OF NICARAGUA.. 



The numerous heavy flooding rains in 

 Western Nicaragua and consequent rapid 

 rise to unusual height of the water in Lakes 

 Nicaragua and Managua (connected with 

 each other by Rio Tapitapa) in November of 

 last year, indicated that in February, 1902,, 

 the water in those lakes would be higher by 

 several feet than the usual annual high water 

 mark, or than since 1859 to 1861, when the- 

 height was about 12 feet above the average, 

 and, consequently, that earthquakes and vol- 

 canic activity would occur. 



The continuous rapid dry current of atmos-
