This ti-ijugh gives excelU'iit satisfaction witli 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 page you will see a, sectional view of it. Tlie 

 grain is put into the hopper, H. It drops in the direction indicated by the arrows into the spaces, AA, 

 where it is eaten by tlie birds. As fast as they eat, more drops down. The strip through which they 

 .slick their heads is three inches wide and the slots are cut with a baud or keyhole saw. The V at 

 tlie 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 antl pilfer the gram. The incli square pieces at the front of the bottom 

 prevent the birds from pecking the grain out on to the floor. One-inch lumber is used in the con- 

 struction for every part except the slot-boards, BB, which are three-eighths inches thick. The top 

 and bottom are of twelve-incli boards, tlie sides of ten-inch boards. The top is held in place by a 

 hook and eye at each end as pictured. The trough will hold from three day.s'to tv.'o 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 liave to enter the unit pen. We have tried all kinda 

 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 tlie size of your Hock, if you wish.
