m JUNGLE PEACE 



we summon them to consciousness and correctly- 

 orient them. It is not without a wrench that 

 we set aside the evidence of our senses and 

 realize the proof which physics offers. We 

 watch the glorious " sunset " and to disillusion 

 our minds require to repeat again and again 

 that it is the earth which is heaving upward, 

 the horizon which is eclipsing the sun and the 

 sky of day. I once persuaded a group of pas- 

 sengers to speak only of the evening's " earth- 

 rise " and in three or four days this term had 

 become reasonable, and almost lost its strange- 

 ness. 



One finds numerous examples of these sensory 

 deceits at sea; our senses are at fault in every 

 direction. The wind flutters the fins of the fly- 

 ing fish and we think they actually fly. The 

 tropic sea, under the palest of green skies, is 

 saturated ultramarine, save where the propellers 

 churn it to pea-green, yet in our bath the water 

 is clear and colorless. 



My most interesting oceanic illusion, was a 

 personal one, a result of memory. I looked 

 about the ship and felt that this at least was 

 wholly sincere; it was made to fulfil every 

 function and it achieved its destiny day by day.
