Vigilant and conscientious oversight is the price of profit and success. An overseer or foreman of a printing-office should be of more than ordinary capacity, and able to keep his temper in firm control. His conduct should be guided by justice and equity in regard to the interests of the employer and the employed. A strict impartiality should be observed in his treatment of the workmen, and no favouritism should be displayed. He should make himself acquainted with the capacity of the men, and apportion work among them accordingly. Some men are valueless except for plain, straightforward composition; others, distinguished for taste and skill, delight in intricate work or matter requiring ingenuity and delicacy, such as tables, music, and algebra. Put one of the first kind on this sort of composition, and he will botch it, and earn small wages; while a workman of the latter class will become restive and dissatisfied with plain, solid matter. While dealing justly with the men under his charge, the foreman should see to it that the employer suffers no detriment from negligent or dishonest practices of unconscientious workmen, whether from careless correcting, allowing dropped types to lie upon the floor, or overcharging, or other methods well known in a printing-office. He should be the first and the last in attendance, in order to satisfy himself that every person does his duty in coming and leaving at the proper time. [Illustration: LARGE SORT-CASE CABINET, FOR SORTS, QUADS, ETC.] The office having been thoroughly swept at an early hour, and the type found in any alley having been placed in the stick of the compositor occupying it, the foreman should pass around the room and see that it is immediately distributed, instead of being thrown on the window-frame or table. The type found in the body of the rooms should be sorted out and distributed at once, and not be allowed to accumulate. No pi should be permitted to remain over till the next day. This is an essential point to secure a tidy and well-regulated office. He should see to it that the proof-roller and press are in good condition, and that a sufficient supply of wetted proof-paper is on hand. A badly-printed proof should never be allowed to go to the proof-reader or to the author, as neither can properly read a blurred or imperfect proof. An author will feel kindly toward an office that furnishes him with handsome impressions of his matter. [Illustration: SORT-CASE CABINET.]
