or effete lime or gypsum as would completely absorb the li- 

 quid parts, and might be so intimately incorporated with the 

 solid parts as to bring all into a feasible state of application to 

 the land. This vault or stercorary should likewise serve as a 

 place of deposit for all dead animals in the place, and all other 

 offensive matters, which might be converted into manure. 

 The contents of the family vault, being freely mixed with 

 mould or spent tan, should likewise be conveyed there at least 

 once a week. This would be a great gain to comfort and 

 health. I saw such an arrangement on one farm, and its ad- 

 vantages were most obvious. It formed an excellent bank of 

 general deposit, whose discounts in the spring were always 

 most liberal and useful. 



The preparation of night-soil for easy use and transporta- 

 tion, has been the subject of various chemical experiments. 

 The prepared article goes under the name of poudrette ; and 

 though there have been occasional disappointments, I have 

 seen it used with great success. The admixture of effete or 

 slacked lime with it has the same effect as any other absorb- 

 ent ; but the application of quick lime, while it destroys its of- 

 fensive odors, expels its ammonia and proportionately reduces 

 its value. Liebig recommends its mixture with gypsum or 

 chloride of calcium or some mineral acid. I have not known 

 this tried. This would fix the ammonia and give it out to the 

 plants as the vital process is prepared to take it up. The 

 mode of preparing it in Paris, is by drying it in large vats in 

 the sun until it can be reduced to a fine powder and loses all 

 smell. Its best properties are then gone. Fine peat, muck, 

 fine mould, powdered charcoal, tanners' bark burnt and charred, 

 are substances which maybe mixed with it to great advantage. 

 It is beyond all question one of the most powerful of manures, 

 but can only be applied advantageously in a prepared state. An 

 establishment for this purpose is about being made in the 

 county which may prove eminently beneficial. 



Bone manure has been tried to some extent ; in some cases 

 within my knowledge, with great and decided success ; in oth-
