URINE. 139 



moisture and carried into the soil, produces 

 the same effects as we have noticed when speak- 

 ing of nitrogen. 



A portion also of the beneficial effect of this 

 application, may be attributed to the charcoal 

 which partly composes it; and which, acting 

 as an absorbent of the ammonia contained in 

 the atmosphere may serve to increase its effect. 

 Another portion may be attributed to the small 

 quantity of saline matter it contains ; but its 

 principal use as a fertilizer is derived from the 

 presence of ammonia. 



Urine — "■ When it is considered," says Lie- 

 big, *'that with every pint of urine, a pound of 

 wheat might be produced; the indifference 

 with which this liquid excrement has been re- 

 garded is quite incomprehensible." 



We can here only join in expressing our sur- 

 prise at such neglect; but we would at the same 

 time fain hope that such neglect has arisen en- 

 tirely from ignorance of its value, and in the 

 zealous endeavours that are now making by 

 agriculturists at large, and the zeal, energy, 

 and ability that is now displayed, we may 

 fairly anticipate a juster appreciation of this 

 manure for the future. 



That we do not overrate the value of this 

 manure, may be proved from the following 

 results of the analysis of 100 parts of wheat 

 manured in different ways, and which places 

 human urine in the very first place as to value. 



We have before stated that the weight and 

 value of wheat as an article of food, depends'on 

 the quantity of gluten it contains, and this 

 fact admitted, no other argument is required
