Some machines as described above, are not adapted to this business, and some men are not adapted to the use of machines even when they are good ones. They are not willing to bestow the little but intelligent and regular care required, and many times during the four weeks they will forget some of the most essential points, such as replenishing their lamps, or forget to attach the extinguishers, thus depriving the machine of all self-control, or they neglect to trim the lamps for days, and perhaps a week, allowing the wick to crust and the heat to decrease. Others of nervous temperament will open their machines every fifteen minutes during the day and get up many times during the night to do the same thing, necessarily creating a great variation in the temperature of the machine. Now, all these, when repeated often enough, mean disaster and grief. One man who had been very successful, said he liked the hatching very well, but there was too much confinement growing chicks and ducks, and he was not going to make a slave of himself any longer. Another very young man who has been uniformly successful, and is running four large machines, said that the hatching and care of incubators was nothing, as he simply looked at his machines twice per day, but that the care of chicks and ducks was hard work; but there was more money in it than anything else he could do, and he should stick to it. Another man, because his machine did not run to suit him, threw his boot at it, knocking the regulation all off, which he called upon me to duplicate. (This man has done better since and increased the number of his machines). So the reader will see that there are cranks even among the poultry men, and that many of them enter the poultry business simply because they are looking for an easy job,--a sad mistake on their part. I have always noticed that the man who knows the least, but is willing to acquire knowledge and follow instructions implicitly, is the man who generally succeeds. Best Place for Incubators. Having secured a good machine, the next thing is to locate it where it will give you the least trouble to run it, and at the same time do you the most good. The best place for this is either in a barn or house cellar or in some building partly under ground, for obvious reasons. Though a good machine can be regulated to run in any temperature (provided it can generate heat enough), yet constant thermal changes of 30 or 40 degrees between night and day will necessitate regulating to meet them,--as the amount of flame required to run a machine in a temperature of 40 degrees, will be far in excess of that needed to run it in one of 70 degrees, for, though the change will be very slow in a nicely packed double cased machine, yet in time even that change will affect.
