A Thriving Family 



FINISHED PRODUCT OE OTHER INDUSTRIES 

 PROTECTED 



Let me now briefly explain why the 

 cattle grower should benefit and why this 

 branch of his industry should be pro- 

 tected. In the first place, the finished 

 products of other great industries, of 

 which his finished product is the raw 

 material, has greater protection, larger 

 duties, than his own. It is estimated 

 that of 1,000 pounds of live stock, 550 

 pounds become dressed beef, leaving 450 

 pounds of non-edible material. This lat- 

 ter is converted into so-called "by- 

 products," the science of converting 

 which has made such progress that there 

 is today practically no waste whatever 

 of this 450 pounds of non-edible material, 

 but, instead, 120 different products, all 



more or less valuable, are secured. So 

 important and interesting is this phase of 

 the subject, that I wish to quote the fol- 

 lowing from a recent article : 



Once the 450 pounds of non-edible material 

 was largely thrown away, although the hide 

 and tallow were utilized. Later, some of the 

 waste products were used in the manufacture 

 of glue. Nitrogen being the chief element in 

 plant food, and this being abundant in the great 

 mass of refuse matter originally thrown away 

 as hopeless waste from all the packers' proc- 

 esses, a most important economic advance was 

 made in the step which turned this large vol- 

 ume of scrappage into fertilizer. 



It is good sense and for the best interest of 

 the world that all material not needed to feed, 

 clothe, and heal the world should be returned 

 to the ground for food for plants, to grow 

 more grain, to feed more cattle, and to feed 

 more people. That is the circle completed by 

 the packer. 



All the cunning of the chemist has been
