moved more backward, the toes and part of the feet al- Particular ob- 

 ways appeared above water, the body continuing in per- gp^^jj^g^^^g^' 

 feet equilibrium, with the face and toes above the surface, situation of 

 the chest and knees close to it. When the water is not floating per- 

 too cold, and the surface smooth, it would be an easy ' 

 matter to fall asleep floating in this position. 



None but those who can swim above and under water 

 will readily comprehend the great pressure of the water 

 upward, and how easily it will sopport on its surface 

 human beings, when it is smooth, without any broken 

 water. For amusement 1 have gone into the sea full 

 dressed into deep water, and by floating in various ways, 

 as most coavenient, taken off coat, waistcoat, opened' 

 the knee buttons of my smallclothes, taken them and 

 stockings ofi^ with equal ease as on shore, and finally 

 pulled my shirt ofi", swimming then with them to the 

 shore. 



Swimming is very easily acquired when a few good 

 lessons are given. Seamen, and others who are liable to 

 be much on the sea, rivers, canals, &c. should not neglect 

 to learn this art.
