Men in engaging employees should be careful to get the best. Understand, you cannot have too good tools to work with, and there is no tool you should be so particular about as living tools. If you get a good one, it is better to keep him, than keep changing. He learns something every day; and you are benefited by the experience he acquires. He is worth more to you this year than last, and he is the last man to part with, provided his habits are good, and he continues faithful. If, as he gets more valuable, he demands an exorbitant increase of salary; on the supposition that you can't do without him, let him go. Whenever I have such an employee, I always discharge him; first, to convince him that his place may be supplied, and second, because he is good for nothing if he thinks he is invaluable and cannot be spared.
