132 GUANO. 



America, where the soil is volcanic or sandy, 

 no produce would be obtained without the 

 Guano. 



"It has been calculated that from 12,000 to 

 14,000 cwt. are annually sold in the port of 

 MoUendo, for the use of the country around the 

 city of Arequipa. In the province of Taracapa, 

 and in the valleys of Tambo and Victor, the 

 consumption should be something more; as 

 wheat, all kinds of fruit trees, and plants, with 

 the single exception of the sugar cane, are ma- 

 nured with the Guano, which is not the case 

 with the district of Arequipa, where maize and 

 the potatoe alone require it. In the district of 

 Arequipa, three cwt. of the Gnano is spread 

 over an extent of 5000 square yards, but in Ta- 

 racapa, and in the valleys of Tambo and Victor 

 five cwt. are required." 



The analysis of Guano yields: 



Phosphate of lime 



Sulphates and muriates 



Lythic acid 



Ammonia 



Other organic matter . 



30^ parts.

It is recommended either to be sown or 

 drilled with the seed, or as a top dressing, and 

 in whatever way it is used, the subsequent ap- 

 plication of a bushel of powdered charcoal is 

 also recommended, as producing effects on the 

 second crop quite equal to those on its first ap- 

 plication. 



It need hardly be stated here, that the use of 

 the charcoal is to absorb the ammoniacal gases, 

 w^iich otherwise would escape and be \^asted.
