The above closes the account of the goods traffic. Any omission or errors in these accounts are corrected in those of the subsequent month, the balances being, in the first instance, always paid as declared by the London railway clearing-house. When the balances are finally struck, a letter is addressed from the office to each company, advising it of the amount due to or by it on the traffic of the month; and, unless these balances are paid by each company within twenty-one days, interest at 6 per cent. is charged, and credited to the companies to whom the clearing-house is nominally indebted. For the convenience of the companies a weekly notice is sent by the London office to each, informing each of the amounts of the receipts of the _through_ goods traffic to which it is respectively entitled. This single operation, which enables the companies to publish their weekly receipts, employs nine clerks. PASSENGERS.--All tickets collected at all the clearing-house stations from _through_ passengers are transmitted daily to the London clearing-house, from whence, after being examined and compared with the returns of the tickets issued, they are sent back to the respective companies. From Euston, as well as from all other stations, passenger tickets for every station are each numbered separately from 1 to 10,000, and are issued consecutively, not only for each station, but for each _class_ of passengers. In examining these collected tickets, which on an average amount to 9000 per day,--in comparing them with the consecutive numbers as entered in the daily Returns received from the various stations,--and in checking the consecutive numbers themselves, five clerks are employed. The railway clearing-office thus receives-- 1. Return from Euston booking-office, as also from all clearing-house passenger stations, stating the number of passengers of each class booked for all clearing stations, the portions of fares paid by each passenger and due to “foreign” companies. 2. From this account the London clearing-house prepares and forwards daily to each company a return, showing the portion of the fares received at Euston due to each respectively. The above returns are despatched on the evening of the second day. 3. The London clearing-house receives daily from every clearing station a similar return.
