our citizens will enjoy a much purer atmosphere than they do at pre- 

 sent, and increased health will be the consequence. When travel- 

 ling in Switzerland and Germany, I uniformly found all the best 

 farmers had large reservoirs under their barns, into which they daily 

 swept all the excrements of their cattle, which are always fed in 

 stalls. They then poured into them six times the bulk of the manure 

 in water; five reservoirs are employed by the wealthy farmers, each 

 large enough to contain all the manure made in a week; they are 

 each allowed to remain four weeks after being filled, to ripen, by 

 which time the whole becomes a uniform liquid mass; it is then 

 pumped into large vessels, carried upon carts drawn by three pair of 

 oxen, to the field, and distributed in a form capable of being taken 

 up at once by the plant. 



A German agriculturist at Frankfort, informed me that all Ger- 

 man farmers had admitted from time immemorial, that blood of cat- 

 tle and human urine were the most powerful of all the fertilizers 

 known, and that, if no other substance was used upon land, it would 

 always produce wonderful results, as they contained, (as has since 

 been proved by analysis,) every ingredient requisite to produce 

 growth in all plants. It is usual in Germany to plow it under im- 

 mediately, to prevent waste by evaporation; before doing so, they 

 frequently add five bushels ot salt to the acre, which they find pro- 

 ductive of favorable results. 



Professor Shubler, of Germany, tried the following experiment: 

 he found a piece of soil without manure, yielded three times the 

 quantity of seed sown, and five times the quantity of seed sown 

 when dressed with old herbage, grass, leaves, &c. 



7 times when dressed with cow dung, 



9 " " " " pigeon's dung, 



10 " " " " horse dung, 



12 " " " " human urine, 



12 " " " " sheep dung, 



14 " " " '* human manure and urine or bullock's 

 blood. 



Thus you see, that of seven fertilizers, the liquid manures, urine 

 and blood, were found to be di'cidedly the most efficacious. Human 

 urine, in a fresh state, was found by Berzelius to contain the follow» 

 ing substances:
