I PHOSPHATE OF LIME. 221 



Portance to that one which requires industry for securing the good 

 the absolute good, which they are capable of bringing The 

 I tendency of the most important fertilizers is to escape and pass off 

 into the atmosphere, or else they are insoluble or in a condition 

 not fully adapted to the wants of vegetables. In the former case 

 there is ammonia, which very soon passes off from the yard where 

 animals are confined and gets beyond the reach of the owner, and 

 we must, when this has taken place, consider it as abandoned pro- 

 perty or a lost material to ^vhich he has no better claim than his 

 neighbor. To preserve it requires industry of two kinds. 1st, thaJ 

 of acquirmg knowledge how he may best secure it; and 2d, manual 

 industry, which consists in putting in execution the means he may 

 have devised after he has acquired a full knowledge of the proper- 

 ties of the substance which he wishes to save. There is an indus 

 try which expends itself unprofitably, which consists in a continual 

 doing but not intelligibly, and hence is wasted and consumed in 

 niere motion. Effective industry knows beforehand what is want- 

 |€d, and It proposes to itself an end, and devises means to secure 

 Ithose end.. The result usually turns upon the amount of know- 

 ledge which IS made to bear upon those means and ends While 

 .then, we find materials for the construction of organized beings 

 |abundant, suflScient in quantity, it is the part of the husbandman to 

 |work up these materials to the best advantage ; and the fact that it 

 irequires ceaseless activity of mind and body, need not on this 

 laccount be considered a faulty arrangement, inasmuch as it brings 

 jliealth and life m the highest degree by the fulfilment of the requir- 

 ed conditions by which both may be possessed.
