ANALYSES OF HORSE-MANURE.

For a fuller discussion of this question, the reader is referred to
Heiden's 'Duengerlehre,' vol. ii. p. 185, and also to Storer's
'Agricultural Chemistry,' vol. i. p. 575. The statements in the
different text-books as to the quantity of manure produced by the horse
are such as naturally to perplex the student. This discrepancy is due,
however, to the different methods adopted by different writers of
calculating this amount. The subject is further discussed in the
footnote to p. 252. The following analyses of horse-manure may be
valuable for reference. They are taken from Storer's 'Agricultural
Chemistry,' vol. i. p. 496:--
