There is a point in connection with this subject that may as well be referred to here. The Isthmus of Suez Railway[36] was opened for traffic in 1858, the same year that the Australian mail service by way of Egypt was commenced. The India and China mails had increased very rapidly during the few previous years, and the greatest trouble and difficulty were experienced in getting them across the desert. The addition of the Australian mails would have overwhelmed the service, but for the opening of the railway. For let it be asked, What number of camels would be required, or what time would they require to take some fifty tons of mails (adding to the transmissions _viâ_ Southampton, those from England and France _viâ_ Marseilles, and from Germany _viâ_ Trieste) across the desert? By means of the Suez Railway, the cost to this country for the conveyance of the mails outwards and inwards through Egypt is £8,000 a year, and eight Janissaries accompany the mails in both directions, for which they are paid £750 per annum. The cost of a combined _army_ of camels, camel drivers and Janissaries would be at least £60,000 a year, and it would be simply impossible to perform the service satisfactorily. We think we have demonstrated that even in 1855 the Post Office services of the country must have totally broken down, were it not for railways. But between 1855 and 1865 the postal business has increased enormously. The number of receptacles for letters[37] has risen from 10,498 to 16,246, the number of letters delivered from 456,276,176 to 720,467,007, of newspapers and book parcels,[38] from 71,000,000 to 97,252,766; samples and patterns, an item of Post Office transmission introduced in 1863, 1,286,116. The amount, in money, of the Money Orders issued has increased from £11,009,279[39] to £17,829,290. With the increase comes the concomitant increase of transmissions through the post. The weight of the Eastern mails has risen from 250 tons a year to nearly 2,000.
