"The mail will be late to-night," observed Miss Lillycrop, with an assured nod. "O no, ma'am, it won't," replied Bright, with an easy smile, and May laughed as they returned to the hall to inspect the work in detail. "Here, you see, we stamp the letters." Mr Bright stopped in front of a long table, at which was standing a row of stampers, who passed letters under the stamps with amazing rapidity. Each man or youth grasped a stamp, which was connected with a machine on a sort of universal joint. It was a miniature printing-machine, with a little inking-roller, which was moved over the types each time by the mere process of stamping, so the stamper had only to pass the letters under the die with the one hand and stamp with the other as fast as he could. The rate varied, of course, considerably. Nervous and anxious stampers illustrated more or less the truth of the proverb, "The more hurry the less speed," while quiet, steady hands made good progress. They stamped on the average from 100 to 150 letters in the minute, each man. "You see, ma'am," remarked Mr Bright, "it's the way all the world over: cool-headed men who know their powers always get on best. The stamping-machine is a great improvement on the old system, where you had to strike the inker first, and then the letter. It just doubled the action and the time. We have another ingeniously contrived stamp in the office. It might not occur to you that stamping parcels and other articles of irregular shape is rather difficult, owing to the stamper not striking flatly on them. To obviate this, one of our own men invented a stamp with an india-rubber neck, so that, no matter how irregular the surface of the article may be, the face of the stamp is forced flat upon it by one blow." "When stamped," continued Mr Bright, moving on, "the letters are taken by boys, as you see, to the sorters. You observe that each sorter has a compartment or frame before him, with separate divisions in it for the great towns only, such as Manchester, Liverpool, Birmingham, Brighton, etcetera. Now, you know"--here he stopped and assumed an impressive explanatory tone--"you couldn't expect any single man to sort the letters for every town and village in the kingdom--could you, ma'am?" Miss Lillycrop admitted that she could not indulge such an expectation, and further expressed her belief that any man who could must be little better than a lunatic. "But every man you see here," continued Mr Bright, "has batch after batch of letters put before him, which may contain letters from anywhere to everywhere. So, you see, we subdivide the work. The sorters you are now looking at sort the letters for the large towns into separate sections, and all the rest into divisions representing the various parts of the country, such as northern, southern, etcetera. The letters are then collected by the boys you see going up and down the hall." "I don't see them," interrupted Miss Lillycrop.
