By successive openings of the railways, the length of which between Calais and Marseilles is 1,190 kilometres, the time occupied in the transit of the Eastern mails through France has been diminished from 108 hours to 28 hours.

I have already stated the total contract service of the Peninsular and Oriental Steam Packet Company, 2,290,320 kilometres.

The annual land service of the Eastern mail is as follows; first, as regards Marseilles:—

It should be explained that the heavy mails that are conveyed by the steamers of the Peninsular and Oriental Steam Navigation Company, between Southampton and Alexandria, are taken across the Isthmus of Suez by separate trains from those which convey the light mails viâ Marseilles; hence, there are ninety-six trips of Eastern mails per annum across the Isthmus for the Marseilles mails, and ninety-six for those viâ Southampton. Thus the total annual length of this great postal service is:—

The weight and dimensions of the Eastern mails have increased very greatly during recent years. This is owing partly to the immense expansion of the trade of England in the Indian, Chinese, and Australian oceans, and partly to the British army in India, consisting of at least three times as many Europeans as previous to the Indian mutiny of 1857. England has also a larger fleet in the Indian and Chinese Waters than formerly. In 1865, the trading interests of England, in the Eastern seas, was as follows, in pounds sterling:—
