Book excerpt: Excerpt from Management of Incubators and Rearers Most of the tank machines are regulated by a capsule, and choice should be given to one that has as little iron as possible in the tripod that goes to form the base for the capsule. 'in some cases the whole of the base for the capsule is iron or brass - a very bad plan, as the heat is conducted from the tank down the arms to the base plate, and so to the capsule, the result being that the damper is kept off the chimney-top long after the drawer temperature has fallen. On the whole, the stirrup fillings and pegged capsules seem to answer the best. The intervening space between tank and case is all the better if packed with mineral wool, fur, or wedding, as heat travels in straight lines. By the use of such substances the lines are broken, and hence do not conduct the heat away to the case, to be parted with again to the surrounding atmosphere Most hotair machines are so packed, and that class of machine that has a hot-air tank similar to the water-tank, or where the hot air is first accumulated and then passed through a woollen diaphragm, seem to give the best results, but I cannot recommend machines where the products of combustion are turned into the egg-chamber. The incubator room should be as good a one as_can possibly be provided. An outhouse will not do. A well-ventilated cellar, or a cellar kitchen which is half above the ground, is perhaps the best room of all. A bedroom with a north window often makes a good room for the purpose, but any room that is used where the 51m shines in should have a dark blind to the window to render the temperature more equable. The machine should be staged at a convenient height, on good, firm benching, and should itself be at least 6 inches from the wall, for if in contact with an outer wall of the room the machine will lose heat on that side of the machine, and the eggs [on that side be lower in temperature than the others This fact alone often accounts for' a poor hatch, for the machine is placed right back against the wall, and the thermometer is on the opposite side. Who can say, then, whether the eggs farthest from the thermometer are receiving su icient heat? When you find chicks hatching out late, you should see whether some such leakage is not taking place; Supposing that you have not started yqur machine in a proper manner first, the next thing is to see that the machine is level, and you cannot be too particular in this respect. If one corner is lower than the other, the temperature. Will vary, and theeggs in either the lower or higher corner be over or under heated, and, as the eggs are usually changed from place to place in the drawer, each in turn will be over or under heated, and the average of the whole hatch spoiled.
