The reservoirs for the collection of the ga- 

 doue, generally contain 35 square yards of 

 matter, or 25 casks each of from 300 to 400 

 lbs. and costing five cents. 



According to Payen and Boussingault, the 

 Flemish manure contains, in its normal state, 

 0.19 to 0.22 per cent of nitrogen. 



For the modes of rendering faecal matters 

 inodorous, and more powerful in their fertili- 

 zing influence than poudrette, see Appendix.
