SELF-FEEDER FOR GRAIN 



SELF-FEEDIITG 



GRAIN TROUGH. It 



IS quite difficult to de- 



\'ise a grain trough 



from which the pigeons 



cannot throw grain 



out, as they poke 



around in search of 



tid-bits. The trough 



illustrated at the top of 



this page is a good one. 



The grain falls down in 



each compartment as 



fast as it is eaten. The 



pigeons when eating 



stand in the front part 



of the trough and if 



they pull out any grain, 



this is not scattered on 



the floor of the squab- ■ 



house but onthe board 



front, from which it 



may be swept up as 



necessary. This pat- 

 tern of trough was de- 

 signed by Dr. P. D. 



Clum. One > s k e t c h 



shows the box without cover and the other with cover in its proper place, protecting 



the entire box and contents from droppings of the birds. The dimensions do not mat- 

 ter. A good size woiild be about four feet long and two feet wide. This would allow 



tor feed compartments about five inches wide, nine in number. 

 The trough for grain illustrated at the bottom of this page is for use when feeding by 



hand twice a day. It was devised by Charles W. Blown. It is simple and open, still 



the birds cannot fou! 

 the grain in it. The 

 size shown in the pic- 

 ture is four inches wide 

 and two inches deep 

 inside, thirty-six inches 

 long outside. Twenty 

 birds can feed at once 

 at this size. The ends 

 are four inches high 

 inside to centre of 

 pivot. These pivots 

 are the feature of the 

 trough and give it its 

 novelty. The birds 

 cannot get into the box 

 and foul the feed be- 

 cause the bar is in the 

 way. As the bar is 

 pivoted and turns 

 when they alight on it, 

 they cannot roost on 

 it. The pivoted wood 

 bar is of one-inch 

 square stock. The box 

 also is of one-inch 

 stock, so as to be heavy 

 and strong. The box 

 is deei) enough to pre- 

 vent birds from throw- 

 ing out the grain when 

 enough for twenty 



birds for one meal is in it. There is space between the edge of box and the bar ample 



for the birds to feed, but not enough space,for them to get into the feeder. The fact 



that the bar is pivoted does not prevent the birds from alighting on it but, being pivoted, 



the bar turns as soon as, they alight on it and off they go. They soon learn to keeo off 



it.
