100 A PHILOSOPHER WITH NATURE 



stretch was a feat which justly entitles to distinction. 

 How was it done ? To be successful it was necessary 

 to take the water bravely, like a retriever, and with 

 a strong breast stroke, which soon lessened the dis- 

 tance between you and your quarry. As you ap- 

 proached, the struggle in the mind of the mother 

 bird was always ludicrous. She was torn between

 but not hurt, streaming from your mouth, you swim 

 to land under the envious and admiring eyes of 

 your equals. You may afterwards worst your
