CHAPTER XXI 



REFRIGERATION AND BY-PRODUCTS 



I HAVE received many interesting letters contain- 

 ing extended information on several subjects that 

 I have touched. I had intended to devote a chapter 

 to a sort of jack-pot condensation of this correspond- 

 ence, but the book is drawing to a close, and my ranch 

 work is coming so fast that I shall only take space for 

 refrigeration. In an early chapter I promised to try 

 to get data as to refrigeration at Denison, Tex., long 

 before it seems to have been used by what are now 

 the "great packers." Data have come to me through 

 Warren V. Galbreath, general live stock agent of the 

 Missouri, Kansas & Texas Railroad. He began his 

 cattle experience as foreman of feeding stations thirty 

 years ago. I have quoted from the best data that 

 Kingan & Co., Indianapolis, in 1885 used the first 

 mechanical refrigeration, and, so far as I know, that 

 stands as applied to the use of cold air pumped 

 through a plant. The use in packing houses of 

 mechanical ice, however, as a substitute for natural 

 ice antedates the cold air process by probably twelve 

 years, and apparently found its earliest use in the 

 south. Its first application to the packing industry 

 seems to have been at Denison, Tex.
