When copy is put into the hands of the compositor, he should receive directions respecting the width and length of the page; whether it is to be leaded, and with white lines between the breaks; and whether any particular method is to be followed in the punctuation and in the adoption of capitals. These instructions being given, the compositor will make his measure to the number of ems directed, which is done by laying them flatwise in the composing-stick, and then screwing it up sufficiently tight to prevent the slide from moving. He then fits a composing-rule to the measure, and, his case being supplied with letter, he commences his work. The left hand, which contains the composing-stick, should always follow the right, which takes up the letters. If the left be kept stationary, considerable time is lost in bringing each letter to the stick, because the right hand has, consequently, to traverse a much greater space than is necessary. The eye should always precede the hand, constantly seeking for the next letter while the fingers are picking up one just selected. Each letter should be taken up by the upper end. This method will effectually prevent any false motion, and preclude the necessity of turning the letter when in the hand. If possible, a sentence of the copy should be taken at one time, and, while putting in the point and quadrate at the end of the sentence, the eye may revert to the copy for the next. It is to dexterity in these particulars that compositors are indebted for swiftness. The time thus gained is very considerable, while all appearance of bustle or fatigue is avoided. By taking a sentence into the memory at one time, the connection of the subject is preserved, and the punctuation rendered less difficult. Those who are careful in distribution find the advantage of it in composition. Foul or slovenly workmanship is disgraceful. To avoid this, a compositor should accustom himself to glance over each line as he justifies it, and correct any error as he proceeds, which he may do with little impediment to his progress. SPACING.
