Upon these poles the manure is piled in a Hat heap, made 

 hollow or dishing at the top, so as to collect all the water that may 

 fall upon it. The heap need not be more than live feet high, which 

 is sufficient to cause an active fermentation to be kept up through 

 the whole of it. The materials of which this heap is composed will 

 include everything of a mineral or organic character useful for 

 manure, that can be procured stable manure, straw, rushes, weeds 

 sawdust, peat muck, leaves, wood, earth, night soil, leather scraps, 

 tanner's waste, butcher's offal, ashes, plaster, and bone dust and 

 the skilful operator will add from time to time such chemical sub- 

 stances as he needs to enrich the compost. The water in the vat 



should be frequently pumped out for use and a fresh supply poured 

 upon the heap. A pump that will not readily be choked should be 

 used. One with a collapsing bucket, with leathern sides, and of a 

 conical form, is the most useful. The waste water from the roofs 

 might be discharged upon the heap by a simple arrangement of 

 spouts. The object desired, vix., to gather every soluble part of 

 the manure into the vat, should be forwarded by every possible 

 means. The distribution of the liquid manure may be (lone by 

 horse or hand cart distributors, or by pipe and no/xle, according to 

 whichever is most suitable.
