The general character of the above mentioued substance resembles 

 that of barnyard manure. It contains more nitrogen and phosphoric 

 acid, and less potash than the average barnyard manure. By 

 increasing the latter ingredient to one-half a per cent, a fair substi- 

 tute for barnyard manure may be obtained.

This refuse from breweries differs from the previously described one 

 merely by a larger percentage of nitrogen, it contains. Supplement- 

 ed by some phosphoric acid and potash it may serve in place of barn- 

 yard manure. The average barnyard manure (partly rotten) is 

 usually stated to contain 0.5 per cent of nitrogen, 0.26 per cent, of 

 phosphoric 'acid and 0.6 per cent of potassium oxide.
