MANURES. 167 



templation to build an aqueduct forty miles long and 

 nine feet in diameter for its distribution. In the 

 experiments made with this manure during the sum- 

 mer of 1867, fifty-three tons of Italian rye-grass were 

 grown on a single acre, nine tons being grown in 

 twenty-two days. 



On the farm of the celebrated Mr. Mechi at Tip- 

 tree Hall, the system was, many years ago, adopted 

 of converting all the manure of the stables into a 

 liquid, and distributing it over the farm by means of 

 uuder-ground pipes and movable hose. Mr. Mec-hi 

 still continues the practice and considers it profit- 

 able. 



This subject is mentioned in this connection, not 

 as affording an example which can be profitably fol- 

 lowed here, so much as because it shows how much 

 expense may be profitably applied to the distribution 

 of manure in a liquid form. 



MIXING. SOILS. 



The mixing of soils is often all that is necessary 

 to render them fertile, and to improve their mechan- 

 ical condition. For instance, soils deficient in pot- 

 ash, or any other constituent, may have that deficiency 

 supplied, by mixing with them soil containing this 

 constituent in excess. 



It is very frequently the case, that such means of 

 improvement are easily availed of. While these 

 chemical effects are being produced, there may be an 

 equal improvement in the mechanical character of
