Ammonia, a trace

It would have been dear at half the price. But why? perhaps you inquire,
do you give these samples of rascality in England? Just to show you what
men are capable of doing there, they will probably do here--nay, have
done. Here is the analysis of an article which was sold in the city of
New York, under the name of _prepared guano_. The analysis was made by
the lately deceased, highly respected, and eminent analytic chemist,
Professor Norton, of Yale College, showing the following result.

Water, 4.35

Alumina and phosphate of lime, 7.82

Organic matter, 32.58

Insoluble matter, 26.05

Carbonate of lime, 28.76

Magnesia, alkalies, and loss, 0.43

This analysis was made by the request of the editor of the Genesee
Farmer, by whom it is not only endorsed, but proof given of its utter
worthlessness upon the land where it was applied. Professor Norton made
the following remarks upon the subject.

"This is indeed a _prepared_ article. You will observe that three tenths
of the whole are water, or matter insoluble in acid, or nothing more
than water and sand. More than another three tenths is organic matter;
this contains scarcely a trace of ammonia or nitrogen in any form, being
worth no more than common muck from a swamp. Thus we have six tenths of
the guano made up of a mixture that as a gift, would not be worth
carting. Nearly another three tenths is carbonate of lime, a valuable
article it is true, but one which can be bought far more cheaply by the
barrel, bushel or ton, than as guano. The remaining tenth contains a
small quantity of phosphates, but not enough to make the mixture of much
value. The parties engaged in this manufacture, should be widely
exposed, for it is one of the most outrageous impositions I have ever
known. Farmers should avoid everything of this nature unless it is
certified to be equal to a copy of analysis shown. This stuff is not
worth transporting any distance for your land. J. P. NORTON."

We will now give the analysis of Peruvian, Patagonian, and Chilian
guano, as determined by Dr. Anderson, chemist of the Royal Agricultural
Society of Scotland, to be a fair average deduced, from a careful
examination
