216 RESULTS OF EXPERIMENTS IN SWINE FEEDING

Make the iron bands (two on each side) connecting the con- 
trol slide at the bottom, with the thumbscrew at the top, of light

in turn presses upon and breaks the meal blockade—they arc 
rarcly left with a “dead” self-feeder. To prevent the pigs 
forcing the board too far in, it is, of course, necessary to place 
a cleat inside at either end of each slide. Allow about 14-inch 
play between the slide and the cleat. 
The second arrangement shown is simple, consisting of a 
section of the gate hinging imward. This the pigs may root 
against, causing it to break any meal stoppage. Possibly the first 
deserihed arangemceut will be found most satisfactory. 
* To ensure the constant feeding of the meal, some means of agitation 
is necessary. Otherwise the contents will block close to the bottom.
