in the region of Gardner’s River offer an exception; they are of a calcareotij^ / < 
nature. These differences are owing to the geological formation of the strata ov#"-^^

The Geysers are one of the forms of thermal springs and present mm ^ ^ 
curious and astonishing phenomena. They are found in many different parts i ^ ' 
our earth and in each place present certain features peculiar to that region. Is ; « 
not wonderful that in the cold and dreary arctic region of Iceland, where tl ^ 
snow and frozen waters exist as permanent adornments of the land, and the fe i 
short days designated out of courtesy Summer, are hardly sufiflcient to melt th 
investiture and give a start to vegetation in the sheltered valleys; is it not wo 
derful, that amid such surroundings there should burst from the earth wat 
having the temperature above the boiling point ? What contrast could be greate 
and what could illustrate more forcibly the great diversity exhibited in all f 
workings of nature ? 
Formerly active geysers were found only in Iceland; lately, however, soi 
exceedingly beautiful and grand fountains of this nature has been discove red
