needed. These lambs were kept in lots made of panels set zigzag, 

 so that, each pair of panels met at a rjght angle and the total nua&er 

 of panels used were so arranged as to form an enclosed yard. One 

 panel fence was 458 feet and the other 462 feet long. These two en- 

 closures were used for 251 and 254 lambs respectively. There w r as 

 more room than was necessary or advisable. When space is sufficient

to encourage it the lambs gather in groups and do considerable run- 

 ning and playing, thereby getting too much exercise for most econom- 

 ical fattening and wasting too much energy. In the spaces mentioned 

 650 to 700 lambs could have been fed without overcrowding. 



The panels or hurdles that enclose the Caldwell Station feed yards 

 are fourteen feet long and three feet one inch in heighth. Ready cut 

 material for making each panel is as follows: 



1 piece of 1x12, 14 feet long. 



2 pieces of 1x6, 14 feet long. 



3 pieces of 1x6, 3 1-2 feet long. 

 25 to 30 6d nails. 



This provides for three horizontal boards, and a vertical binding 

 slat at each end and one in the middle of the panel. The 1x12 is used 

 for the bottom horizontal board and the vertical slats should be ex- 

 tended five inches below it. In erecting the panels into a fence these 

 5-inch lengths are sunk into the ground to make the enclosure more firm. 

 Above the 1x12 is an eight-inch space through which the lambs reach
