 cathedral of Strasburg, the highest of any cathedral 

 of the globe, which sends its lofty pinnacle to the 

 height of four hundred and forty-six feet ; or in the 

 great pyramids of Cheops, four hundred and eighty 

 feet high, which, if raised in our ranges, would be 

 overshadowed probably by Eucalyptus trees." 



In one sense a giant, and in another sense a dwarf, 

 there is no more remarkable plant to be found than 

 that called after the name of its discoverer, Dr. 

 Welwitsch {Welwitschia mirabilis). "Several miles 

 before reaching Cape Negro the coast rises to a 

 height of about 300 or 400 feet, forming a continuous 

 plateau, extending over six miles inland, as flat as a 

 table." Amongst the vegetation of this plateau a 

 dwarf tree was particularly remarkable. This, "with 

 a diameter of stem often of four feet, never rose
