JAMES WATT'S MONUMENT. 83 



find Watt's monument at work at every village. 

 Would you travel by land ? that monument shall 

 carry you along as fleet as the winds. Would you 

 travel by water ? Heed nothing for wind and tide, 

 for James Watt's monument will overcome these 

 for you. That monument is at this moment di- 

 viding the waters of every navigable stream, and 

 the waves in every ocean, in and between all 

 highly-civilized and active countries; and if, when 

 one is in St. Paul's, " look around " be enough of

 Wren, climb the highest mountain, get the most 

 ample range of land and sea; and, in what 

 part soever of the busy world it may be, " LOOK 

 AROUND" will still be the epitaph of James Watt. 

 But what he and his co-operatives have done, is 

 but a single series of the applications of that one 

 property of water. Those applications are very 

 many, and our salt-making is one and a highly 

 important one ; and there are places where if the 

 people could find materials they would prize the 

 making of salt more than the making of gold. 

 It is reported that there are some tribes in Africa 

 who give away gold dust, but reckon value in salt 

 as we do in money. Well, the moment that the 

 water is raised to the boiling point, it will receive 

 no more heat into its substance, or allow any 

 more to pass through without exerting the resist- 

 ance to which allusion has been made ; and if it is 

 not every where resisted in return by something 

 stronger than its own resistance, a portion of the 

 water goes off, and carries the heat along with it, 

 so that the water where it just begins to mingle 

 with the air is far hotter than it is at the bottom of
