board, 1 inch in diameter (so as to remove tank when necessary )j which 

 leaves a small space in front of the sliding board to be filled with saw- 

 dust. Have the tank tube in front 

 only long enough to extend through 

 the sawdust in front, and have your 

 faucet to screw into this tube, the 

 tube being threaded. The tube on 

 top of tank should be long enough to 

 extend through the tops of hotli boxes 

 (outer and inner, through the saw- 

 dust"), and should, therefore, be 7 

 inches high from top of tank, as is 

 seen at figure 5. When the incuba- 

 tor is ready, we have figure 5, which shows the sawdust packing in front, 

 by looking into the opening into which the Qg^ drawer enters when filled 

 with eggs. 



Figure 6 shows the incubator as if cut in half lengthwise, and displays 

 all the positions. What

is meant by the "boxed- 



off" portion in front, is 



that portion filled with 



sawdust in front. The 



side boards of the inner 



box are joined, on their 



front ends, to the front 



boards of the outer box, 



being also nailed to the 



two short middle posts. 



Fill in between the boxes 



with sawdust, and if saw- 

 dust is scarce, use chaff, oats, finely-cut hay (rammed down), or any- 

 thing that will answer, but sawdust 

 or chaff is best. In figure 6 ^ is the 

 tube on top, B the faucet in front, 

 C the opening for the egg drawer, 

 and Z> the tube to admit air into the 

 ventilator. This tin tube should bo 

 as close to the bottom of the ven- 

 tilator as possible. When making 

 incubator, do not forget to cut holes 



for tubes oi tank and also for air tubes to come through, and then putty 



around them.
