The food contains 52 lbs. of nitrogenous matter; the increase of pig contains 7 lbs., and consequently, if there is no loss, the manure should contain 45 lbs. of nitrogenous substance = to 7.14 lbs. of nitrogen.
“In other words,” said the Doctor, “the 70 lbs. of dry liquid and solid pig-manure contains 7.14 lbs. of nitrogen, or 100 lbs. would contain 10.2 lbs. of nitrogen, which is more nitrogen than we now get in the very best samples of Peruvian guano.”
“And thus it will be seen,” said I, “that though corn-fed pigs, leaving out the bedding and water, produce a very small quantity of manure, it is exceedingly rich.”
The table from which these facts were obtained, will be found in the Appendix—pages 342-3.

“It will do more good if fermented,” said a German farmer in the neighborhood, who is noted for raising good crops of cabbage, “but I like hog-manure better than cow-dung. The right way is to mix the hog-manure, cow-dung, and horse-manure together.”
“No doubt about that,” said I, “but when you have a good many cows, and few other animals, how would you manage the manure?”
