xv boards, to keep the sawdust from spilling. Of course, 
ne 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. 
{t allows the air to pass through to the eggs for ventila- 
tion. 
Having prepared the tank, let it he 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 
sides 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 pucking, 
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 throngh, as also the spigot in front. The front
