MANURES. 171 



Twent3'-five barrels of hen-manure, at $1 per barrel, . . $25 00 



Twelve barrels of bone, 180 pounds each, at $22.50 per ton, 24 30 



Kainite, about 12 00 



Expense of composting, 5 00 



Cost of teaming manure, 5 00 



Total, $71 30 



It will be seen that the cost of the mauure on the ground, 

 and mixed, was about $24 for each acre of cabbage. Any 

 farmer of experience knows that, as a rule, to insure a first- 

 rate crop of each of these varieties of cabbage, at least six 

 cords of good, stable-manure to the acre would be required ; 

 and as every farmer of experience also knows, such manure, 

 landed in the field, costs on the average $10 to the cord, 

 which would make the cost for each acre of cabbages, $60, on 

 the side of barn-manure, and for the three acres, $180, against 

 $71.30 on the side of the mixture. 



But the common farmer may say that the six cords will 

 leave residue in the ground which the grass-crop will find 

 when the land is laid down. True ; but so will the mixture 

 leave considerable of phosphate of lime, potash and salt behind 

 it. But raising cabbages on such a scale belongs to market- 

 farming rather than to common farming, and those who follow 

 it only at long intervals, lay land down (grass is the poorest 

 return they get) , and meanwhile for many years every acre 

 receives just about as much manure one year as another, but 

 little or no account being taken of what might be left in the 

 soil by the preceding crop.
