I said that each type-setter has his number. We will suppose that this man, next to us, is number "twenty-five." Then he is provided with a great many pieces of metal, just the width of a column, with his number made on them--thus: "TWENTY-FIVE." Every time he sets a new bit of copy, he puts one of these "twenty-fives" at the top; and when all the bits of type in the long trough are slid together the type is broken up every two inches or so, with "twenty-five," "thirty-seven," "two," "eleven," and so on, at the top of the bits which the men, whose numbers these are, have set. When a proof of the article is taken, these several numbers appear; and, if there are mistakes, it appears from these numbers, what type-setters made them, and they have to correct them. Also, of each article, a single "proof" is taken on colored paper. These colored paper "proofs" are cut up the next day, and all the pieces marked "twenty-five," "thirty-seven," and so on, go to the men who have these numbers, and when pasted together show how much type, number "twenty-five," "thirty-seven," and so on, are to be paid for setting--for the type-setters are paid according to the amount of type which they set. [Illustration: Add Yellow Fever Eight new cases of yellow fever--four whites and four colored--were reported to the Board of Health to-day. But one death has occurred since last night, Archie P. Kehoe, son of the late Captain P. M. Kehoe, who died beyond the city limits. THIRTY-FOUR In addition to the new cases reported to the Board of Health, the following persons were stricken with the fever to-day: Lyttleton Penn; P. S. Simonds, an ex-policeman; Jessie Anderson, Mrs. John Bierman, and R. T. Dabney, the Signal Service officer, who it was thought had a mild attack of the fever about three weeks ago.
