28 THE AMERICAN FANCIER'S kept as near this as possible during incuba- tion, but it has been found that the tem- perature may rise as high as no degrees without injury to the eggs, provided it does not remain at that point more than a few minutes; or it may fall to a very low point for a short while. In operating an incubator the con- ditions surrounding it have much to do with its success. These the operator must study and learn by practice. Many theories have been advanced by persons who have ob- tained certain results under given con- ditions, and when tried by another the attempt has proven an entire failure in every detail. A close observation of the machine under the conditions directly sur- rounding it must govern the operations of it and not the theories of others. Try the machine thoroughly before filling it with eggs, and then watch the development with care and patience in attending to the details of the hatch. A good plan for an incubator is the following, which is taken from the Youth's Companion. It has no way of regulating the temperature other than is found in its construction. Make a pine box somewhat like a com- mon washstand, without the inside divisions as shown in Fig. i. About a foot from the floor of this case place brackets like those shown in Fig. 2, and on a level with these screw a strong cleat across the back of the case inside They are to support the tank I he tank should be made of galvanized iron' three mches deep and otherwise propor- tioned to fit exactly within the case and rest upon the brackets and cleats, as shown in v!g* £ uM ^he t0p of thistank in the centre should be a hole an inch in diameter with a nm two inches high, and at the bottom towards one end, a faucet for drawing off the water. When the tank is set in the case ■ nil up all the chinks and cracks between the edges of the tank and the case with plaster of Paris to keep all the fumes of the lamp * from the eggs. Fill the tank at least two inches deep with boiling water. To find when the right depth is acquired guage the water *lth a small stick. Over the fop of the tank spread fine gravel to the depth of a quarter of an inch, over this lay coarse
