by loosening the ordinary bale is compressed into square 

 or cylindrical packages of smaller and more compact 

 form than the ordinary bale. The hydraulic presses used 

 for making the round bales are similar to those used 

 for the cylindrical bales of cotton. The measurements of 

 the different types of double-compressed bales are about 

 as follows: Square, 15 by 18 by 38 inches, weight 160 

 pounds; square bale for Alaskan trade, 14 by 18 by 26 

 inches, weight 100 pounds; round bale, 2 feet in diam- 

 eter, 24 inches long, weight 145 pounds, or 36 inches 

 long, weight 260 pounds. The saving of space in transit 

 may best be understood by comparing the weight and 

 cubic contents of baled and compressed hay. The ordi- 

 nary bale occupies 140 to 160 cubic feet per ton, and 

 round bales 55 feet per ton. The most essential point in 

 loading new hay into a car is to see that it is not loaded 

 flat, that is, with the flat sides of the bale up. When 

 loaded in this way, with the smooth sides of the bales 

 together, no space is left for air and as a consequence the 

 hay not infrequently heats. A properly loaded car has the 

 edges or rough sides of the bales together. This allows 

 air space between the bales and always prevents danger 

 of heating. 



A new machine is being introduced which makes ( from 

 the windrow if desired) a cylindrical bale, with a hollow 

 space lengthwise through its middle. This open space 

 must undoubtedly facilitate the curing of hay baled before 

 sufficiently dry. The machine has a capacity of four to 

 six tons per hour, makes a bale thirty-six inches long and 

 twenty inches or less in diameter, as desired, bound with 

 twine, and the hay can be eaten from the bale, with a
