THE SCENERY OF THE ISLAND 109 



are gradually receiving an answer. Geology has the 

 advantage that it can be studied by all who take walks 

 in the country, and especially by those who visit any part 

 of the sea coast, without the need of elaborate and costly 

 scientific instruments and apparatus. Any country walk 

 will suggest problems for solution. I have tried to lead 

 you to observe nature accurately, to think for yourselves, 

 to draw your own conclusions. I have shown you how to 

 try to solve the questions of geology by looking around you 

 at what is taking place to-day, and by applying this 

 knowledge to explain the records which have reached us 

 of what has happened in the past. You are not asked to 

 accept the facts of the geological story on the word of the 

 writer, or on the authority of others, but to think for 

 yourselves, to learn to weigh evidence, to seek only to find 

 out the truth, whether it be geology you are studying or 

 any other subject, and to follow the truth whithersoever 

 it leads.
