Suppose at Christmas a man has 100 presents to distribute in various localities. A messenger for each of the 100 presents would mean an expense of say $50 and much wasted energy. A single messenger could so systemize the work, by mapping out the shortest routes, that he could accomplish the work in far less time, comparatively, than the 100 messengers, and his bill would be only about $5. Now, suppose the man should ascertain that each of his 199 neighbors in the block also had 100 presents to deliver. That would make 20,000 presents in all. If each man should employ a separate messenger it would cost about $1,000. One messenger would go to First street and leave a package (little knowing that another messenger was to deliver a package at perhaps the very next door), thence to--say Nineteenth street, thence to a distant section of the city, thence to still another district, and so on. Each of the 200 messengers would have the same long journey to make, wearing out his shoe leather, making the cars do useless work, and wearing and wasting his own energy. But suppose the 200 neighbors should combine and co-operate. They would soon find that about five messengers could deliver their 20,000 presents in about the same time that 200 could; and, at $5 each, or $25 in all, with a saving of $975 to themselves. Mapping out the city in five districts and assigning one messenger to each, they would probably find that many presents were to be delivered in adjoining houses, and some to different residents of the same house. Witness the many steps that have been saved, and the time, and the labor of 95 men who have thus been freed to work in some productive vocation. Method and system are parents of economy. They allay waste, eliminate useless labor, and lighten and lessen the toil of the human family. ANOTHER ILLUSTRATION. Some morning at break of dawn witness the confusion in the simple industry of delivering milk. A wagon rattles up to your door and leaves a bottle of milk. It clatters down the street and leaves a bottle to a neighbor in the next block. Then it turns down the avenue and leaves a bottle several blocks away, and thence perhaps to a distant section. But watch, and you behold another wagon coming. It stops at the next house to yours and deposits a bottle on the window-sill, then dashes down the block and leaves a bottle at some distant house, then to a house perhaps several blocks away, and so on until it has covered, in spots, a large territory. Soon, a third wagon appears and leaves a bottle at the second house from yours, and then dashes away to distant parts to cover its route. And so on until nearly 200 different wagons, or grocer clerks, have visited the 200 houses in your block to deliver 200 separate bottle of milk. In every block the same scene is being enacted. Remember that every employer has horses, wagons, harness, drivers, a store, books, a cashier, advertising, fuel, light, and a plant to maintain.
