By such enrichers nourislinient for plants may be more equally 

 diffused through the soil, and becomes more rapidly and surely 

 beneficial to the crop than by any other known mode of cultiva- 

 tion, and you will find by practice, that a vastly more minute 

 quantity of manure, uniformly and equally mixed with land, 

 is sufficient for the purposes of fertilisation than you imaghied. 



My advice to you is to go on and try experiments. If you are 

 successful, you will deserve the thanks of the agricultural interest 

 of the country ; and if you are unsuccessful, you will still be 

 entitled to praise for pointing out errors by the acquisition of 

 knowledge. 



Professor Schubler, the writer of the most esteemed, and cer- 

 tainly the most able treatise on Agronomia, or the best mode of 

 farming and treating eV"ery species of land, added to the experi- 

 ments of Hembstadt, and formed the following valuable table : 

 to wit, 



If a given quantity of land sown without manure yield three 

 times the seed. employed, then the same quantity of land will 

 produce, five times the quantity sown when manured with old 

 herbage, putrid grass or leaves, garden stuff, &c., seven times 

 with cow dung, nine times with pigeons' dung, ten times with 

 horse dung, twelve times with goats' dung, twelve times with 

 sheeps' dung, fourteen times with human urine or bullocks' blood. 

 But if the land be of such quality as to produce without manure 

 five times the quantity sown, then the hors» dung manure will 

 yield fourteen, and human manure nineteen, two-thirds the 

 quantity sown. 



In addition to this information it was ascertained that the most 

 important crops, yielding the most profit, such as flax, can only be 

 obtained in abundance and of the finest quality, by employing 

 human manure. 



By far the most important point of practical knowledge in this 

 matter, put forward by the same great authorities, is that while 

 the manuring with human excrement has produced fourteen times 

 the quantity sown, where horse dung has only yielded ten ; the 

 proportion of the human manure employed was, to that of the 

 horse dung, as one to five only ; so that with one ton of human
