222 ARTIFICIAL MANURE. 



is, till the salts fall, may be used to slack lime. 32 bushels 

 thus slacked, mixed with 40 loads of peat, and spread on 

 one acre of poorest fallow, were equal to any manure. 



Mr. Mitchell, a surgeon in Ayr, recommends 8000 gallons 

 sea water to be evaporated to 600 gallons, and this is to be 

 used to slack 64 bushels of lime. This may be applied to 

 two acres. 



Salt water peat mixed with lime, has been very success- 

 fully used in some places in England. The peat being satu- 

 rated with sea-water by its natural position, is dug out, par- 

 tially dried, and mixed with about } its bulk of slacked 

 lime. It soon heats, ferments strongly, and when used soon 

 after as manure, produces excellent effects. Doubless, all 

 peat saturated with strong brine, and then mixed with lime, 

 would be equally as effective as submarine turf. 



But there is still another form in which this artificial 

 manure may be prepared, that is by the addition of ammo- 

 nia. Take 



3 cords of peat, 

 61 lbs. sal-ammoniac, 

 J cask, or about 61 lbs. lime. 



Slack the lime, dissolve the sal-ammoniac, and wet the peat 

 well with the solution through every part. Then shovel 

 over, mixing in the lime accurately. We have here, then, 3 

 cords of manure, at a price as follows : 



3 cords peat, $4.50

It will be observed that three cords are used in these cal- 

 culations, because the quantity of salts used is equivalent to
