The following statement exhibits the amount paid by the Post Office to the Railway Companies of the United Kingdom in 1866, together with the mileage length of most of them. Of the total sum of £570,500, the London and North-Western, with its 1,320 miles of railway, naturally earns the largest share, £132,997. The other railways come as follows:—Great Western (1,311 miles), £50,789; North Eastern (1,229), £41,397; North British (732), £8,696; Great Eastern (710), £22,357; Midland (695), £44,600; Caledonian (574), £29,101; London and South-Western (503), £21,950; Great Northern (441), £9,805; Lancashire and Yorkshire (403), £6,500; South Eastern (330), £23,571; London, Brighton and South Coast (320), £1,977; Manchester, Sheffield and Lincolnshire (246), £2,618; North Staffordshire (144), £1,000; Bristol and Exeter (134), £9,888; Cambrian (130), £2,413; South Devon (110), £7,485; London, Chatham and Dover (94), £268; Brecon and Merthyr (68), £50; Cornwall (66), £5,500; Taff Vale (63), £1,000; Shrewsbury and Hereford (51), £2,030; Llanelly (46), £39; Monmouthshire (44), £147; Birkenhead (43), £2,500; North Union (40), £4,878; Maryport and Carlisle (28), £841; West Cornwall (27), £1,500; Isle of Wight (12), £31; Whitehaven Junction (6½), £363. There were not any contracts in 1866 with the Furness Company (85), the Somerset and Dorset (66), nor with the Metropolitan Underground (4¾), but the Post Office has recently entered into contracts for the conveyance of mails on the first and the third of the three. The foregoing, with some payments to minor companies, make the total which the English and Welsh Companies receive from the Post Office, £407,512. Some of these minor companies, however, are not over-handsomely paid; for instance, the Colne Valley, 6½ miles long, receives the modest sum of £15 a year; the Tenbury, 5¼ miles long, which nevertheless has a Board of Directors consisting of seven members, and is presided over by a noble Baron, receives only £7. Never having heard of the Pontop and Jarrow Railway, we looked in all the usual sources of information without success, but we perceive by the Post Office estimates that the company earns £5 a-year for the services it renders to the department. If the amounts paid by the Post Office to English Railways be divided by its total mileage, it makes the average payment per mile per annum to them a little less than £58.
