SELF-FEEDER FOR GRAIN. 
This trough gives excellent satisfaction with us. _We do not sell it, but will 
tell you how to have it made. It is four feet long. ‘At the bottom of this pee 
you will see a sectional view of it. The grain is put into the hopper, H. It nope 
m the direction indicated by the arrows into the spaces, AA, where it is eaten by 
the birds. As fast as they eat, more drops down. ‘The strip through which they 
stick their heads is three inches wide and the slots are cut one and one-half inches 
wide, The V at the bottom of the trough is made from a, solid piece of four by four. 
It is solid so that rats cannot get inside of it and hide and pilfer the grain. The 
inch-square pieces at the front of the bottom prevent the birds from pecking the 
grain out upon the floor. One-inch lumber is used in the construction for every 
ae except the slot-boards, BB, which are three-eighths inch thick. The top and 
ottom are of twelve-inch boards, the sides of ten-inch boards. ‘The top is held in 
pee by a hook and eye at each end as pictured. The trough will hold from three 
ays’ to two weeks’ supply of grain, depending on the size of the flock. Put the 
trough not in the flying pen, but inside the squab house. Or, you may build a 
half-trough (slot-board down one side only) and set it in the passageway, and it 
will fill the space between the lower tier of nest boxes and the floor. Here it may 
be filled from the passageway, and you will not have to enter the unit pen. We 
have tried all kinds of self-feeders and recommend this pattern as the best of all. 
If you adopt it in connection with the dowel system (illustrated on previous page) 
your dowels will be used only behind the drinker, this trough taking up four feet of 
the rest of the space. Make it either longer or shorter than four feet, to suit the size 
of your flock, if you wish.
