or boards, to keep the sawdust from spilling, Of course, 

 the egg-drawer must be made longer than the tank and 

 ventilator, in order to allow for this space which it fills 

 in the opening, which is the packing all around the in- 

 cubator. The bottom of the egg- drawer should be made 

 by nailing a few slats lengthwise to the under side, or 

 rather fitting them in nicely, and over the slats in the 

 inside of the drawer a piece of thick, strong muslin 

 should be tightly drawn. On this muslin the eggs are 

 placed in the same position as if laid in a hen's nest. 

 It allows the air to pass through to the eggs for ventila- 

 tion. 



Having prepared the tank, let it be covered with a 

 close-fitting box, but the box must not have any bottom. 

 This is to protect the tank against pressure of water on 

 the sides, and to assist in retaining heat. Such being 

 done, place your ventilator first, egg-drawer next, and 

 tank last. Now place a support under the tank and the 

 box, or have them rest on rods, and as the weight of 

 water will be great in the centre, the iron rods should 

 be placed crosswise under the tank every six inches. 

 Now fasten the three apartments (ventilator, egg- 

 drawer, and tank) together, with boards nailed to the 

 Bides and back and front (of course leaving the opening 

 foi the egg-drawer), care being taken to drive no nails 

 n the egg-drawer, as it must move in and out, and 

 should have a strong strip to rest on for that purpose. 

 Having completed these preparations, make a larger 

 box to go over all three, so that there will be a space on 

 the sides, back, front, and on top, but as the ventilator 

 must be filled with sawdust to within one inch of the 

 top of the tubes, it serves for the bottom packing. 

 Make the outer box so that there will be room for filling 

 all around the inside box with sawdust, and also on top, 

 being careful to let the tube for pouring in the water 

 come through, as also the spigot in front. The front
