This is the table, as given by Dr. Voelcker. For the sake of comparison,
we will figure out what the changes would be in a heap of five tons
(10,000 lbs.) of manure, when fermented under cover, precisely in the
same way as we did with the heap fermented in the open air, exposed to
the rain. The following is the table:

Contents of a Heap Of Manure at Different Periods. Fermented Under
Cover.
