a tin tube, 1 J inches in diameter and 2 feet long, placej in the front part 

 of the ventihitor to admit air. Observe, however, that figure 2 does not 

 show the sawdust in front, as will be explained. We will now take up 

 the separate parts. First is the ventilator. This is simply the bottom 

 of the inner box, being under the egg-drawer, 5 inches deep and 30 inches 

 wide, (the side boards of the inner box being its sides). The front end 



is boxed off, which includes the front 

 boards and also the sawdust, thus 

 making ventilator, inside measure- 

 ment, 36 inches long. E is the tin 

 tube, for the admission of air, before 

 mentioned. Use no sawdust in the 

 ventilator, but paper the bottom well 

 and close, so as to have no air enter 

 except through the tin tube. The 

 tin tube is open at the front on out- 

 side of incubator, and enters into ventilator. 



Egg" drawer. The egg drawer goes under the tank, and rests on the 

 strips D D (figure 2). The egg drawer is 4 inches deep, outside mea- 

 surement. It is 39 inches long, outside measurement (which includes 

 the boxed-off portion in front of 

 drawer), and is 30 inches wide. Three 

 movable trays, each 1^ inches deep, 

 are fitted in egg drawer. Nail strips 

 1 inch wide and f of an inch thick, 

 1 inch apart, the length of the egg 

 drawer (but not under boxed-off por- 

 tion) for the bottom. Mortice ends 

 of strips in egg drawer, so.:as to have 



the bottom smooth. Tack a piece of muslin on these strips (thin muslin 

 is best), and tack it on the inside of the drawer. Now nail strips to 

 bottoms of trays (use lath, if desired, cut to 1 inch width), but you 

 need not mortice them. Simply nail them on the bottom, 1 inch apart, 

 running lengthwise, and tack muslin on the bottom of the trays, inside^ 

 in the same way as for egg drawer. The inside of your drawer will be 

 3 inches deep. The sawdust in front of egg drawer (the boxed portion) 

 fits in boxed front of incubator (see figure 5). Put a broad cap on out- 

 side of egg drawer, at front end, to exclude air. 



The tank. This is 30x36 inches, and is 7 inches deep. It is supported 

 by the stiips G C. and rods FFFF(^gure 2). Being 36 inches long, 

 it goes close up t(/ the back boards of the inner box, the front being 

 enclosed by a sliding board, secured with upright strips at each end ot
