CHAPTER XII. 



LARD OIL, ETC. 



MUCH interest has been felt in the subject of oil from 

 lard, and the almost daily inquiries respecting its process 

 of manufacture, and its close connection with the question 

 of disposing of our agricultural products, forms a reason 

 for giving it an extended consideration. Complete suc- 

 cess has attended the enterprise. Several large factories 

 for the manufacture of this oil, have been some time in 

 operation in Cincinnati, and thousands of gallons are daily 

 prepared for home consumption* and exportation. It is 

 also carried on at Cleveland, Ohio ; Chicago, Illinois ; 

 Burlington, Iowa ; Hannibal, Missouri ; and other places 

 both in the Western and the Atlantic states. 



It is considered much superior to olive or sperm oil, for 

 machinery, and for the manufacture of woollens, etc. 

 It can be furnished also at half the price, and therefore it 

 will doubtless supersede the article of import. As it con- 

 tains less gelatine than other oils, it is found much better 

 for combing wool. Repeated experiments, too, have shown 

 that for the purpose of combustion, no oil is superior. It 

 is important, in trying it with this view, to obtain a good 

 article, manufactured from good lard, and not from the 

 dark-burned, which creates smoke and clogs the flame. 

 For want of sufficient care in this respect, some have no 

 doubt met with disappointment in their attempts to substi. 

 tute this oil for sperm oil in the lamps. 



The following are given as the relative constituents ol 

 lard oil and sperm oil, in one hundred parts of either :
