the risk of accidents from fire, to reduce the cost of manufacturing.
"Long before a factory has reached this extent, it will have been found necessary to establish an accountant's department, with clerks to pay the workmen, and to see that they arrive at their stated times; and this department must be in communication with the agents who purchase the raw produce, and with those who sell the manufactured article." It will cost these clerks and accountants little more time and trouble to pay a large number of workmen than a small number; to check the accounts of large transactions, than of small. If the business doubled itself, it would probably be necessary to increase, but certainly not to double, the number either of accountants, or of buying and selling agents. Every increase of business would enable the whole to be carried on with a proportionately smaller amount of labour.
As a general rule, the expenses of a business do not increase by any means proportionally to the quantity of business. Let us take as an example, a set of operations which we are accustomed to see carried on by one great establishment, that of the Post Office. Suppose that the business, let us say only of the London letter-post, instead of being centralized in a single concern, were divided among five or six competing companies. Each of these would be obliged to maintain almost as large an establishment as is now sufficient for the whole. Since each must arrange for receiving and delivering letters in all parts of the town, each must send letter-carriers into every street, and almost every alley, and this too as many times in the day as is now done by the Post Office, if the service is to be as well performed. Each must have an office for receiving letters in every neighbourhood, with all subsidiary arrangements for collecting the letters from the different offices and re-distributing them. To this must be added the much greater number of superior officers who would be required to check and control the subordinates, implying not only a greater
