148 , .URINE. 



ample means exist for bringing all the waste 

 lands gradually into cultivation, that we have 

 the power, if we have the inclination, to do so. 

 And the circumstances of an increased and 

 rapidly increasing population, may compel 

 a much more attentive consideration, than this 

 subject has hitherto received, and one which 

 eventually must lead to the benefit of all 

 classes concerned. 



So much for human urine. The urine of 

 animals, as previously stated, from the nature 

 of their food, contains much less nitrogen than 

 that of man ; but is equally, and in many cases, 

 much more rich in the saline properties it con- 

 tains, such as the phosphates of magnesia, 

 and the salts of potash and soda. They are, 

 therefore, by no means to be neglected, and 

 indeed all the remarks appended to the sub- 

 ject of human urine apply here only with 

 lesser force. We would, however, recom- 

 mend, that all stables, farm-yards, sheds, and 

 other places where cattle are kept, should be 

 so arranged, as for the urine to be saved, and 

 applied in the manner we have before de- 

 scribed. 



Connected with this subject it may here be 

 stated, that the strong volatile smell, which is 

 almost overpowering, when entering a close 

 confined stable, where many horses have been 

 shut up for the night, arises entirely from the 

 volatilizing of ammonia in the urine. 



A very simple, and at the same time a very 

 profitable way, of correcting this injurious 

 atmosphere, is to strew the stable with gyp- 

 sum, which would absorb the ammonia at once
