I have made out the following table, showing what would be the changes
in a heap of 5 tons (10,000 lbs.) of manure, spread out in the yard, so
that we can readily see the effect of this method of management as
compared with the other two methods of keeping the manure in compact
heaps, one exposed, the other under cover.

The following is the table:

Contents of the Mass of Manure, Spread Out in Farm-Yard, and Exposed
to Rain, Etc.
