366 BOAKD OF AGRICULTURE. 



given throughout Europe will be noticed from the copies of 

 two busiuess circulars but recently published. 



A. — Circular of Messrs. Dreyfus, Freres & Co., of Paris. 



[These gentlemen are the sole contractors for the sale of 

 Peruvian guano in Europe and its colonies.] 



"We announce hereby that we have secured, in consequence of an 

 arrangement between the Peruvian government and ourselves, the 

 sole right of rendering the Peruvian guano soluble by means of 

 sulphuric acid. 



" This arrangement has been made, partly on account of the many 

 complaints concerning the moist and dough-like condition of the 

 lately imported cargoes of guano, partly to render it possible for us 

 to comply with the general and just demand of our customers to 

 furnish the Peruvian guano with a guarantee of a definite composi- 

 tion. Our process removes the lumps usually found in the raw 

 guano, changing them into a dry, pulverulent mass ; it combines 

 the nitrogen in a suitable form, preventing thereby its evaporation ; 

 it renders the insoluble phosporic acid present, soluble ; and thus 

 enables us to guarantee a definite composition, a result impossible 

 in case of the raw guano. We believe that the agriculturists of 

 Europe will be pleased with our arrangements, by which we are able 

 to offer everywhere in Europe, besides the raw imported guano, also 

 a dissolved guano of a uniform state of composition, and with a 

 guaranteed percentage of nitrogen and phosphoric acid. 



" The manufacture of the dissolved guano will be carried on by 

 Messrs. Olendorff & Co., of Hamburg, whose process was introduced 

 many years ago into German}', where it has since been crowned 

 with the most satisfactory results. These gentlemen will manage 

 the entire operation throughout Europe and the colonies. They 

 have already large establishments in Hamburg, Emmerich on Rhine, 

 Antwerp and London, and are preparing for the erection of similar 

 accommodations in France. The sale of the dissolved guano will 

 be everywhere attended to b} T those of our agents who sell the raw 

 Peruvian guano." 



B. — Circular of Messrs. Olendorff & Co., of Hamburg. 



These gentlemen are the sole importers of Peruvian guano 

 for Germany, Austria and Northern Europe ; they are also, 

 as has been seen from the previous statements, the sole man- 

 agers of the manufacture of the "Dissolved Guano."
