THE stupendous project of bringing Calcutta within seven or eight days of London, by means of the Euphrates valley railway route, will probably not take place in our days; but, incredible as it may seem, we yet hope we may look forward to its being carried out in those of our children. Some persons may possibly smile, and say, "It is the scheme of a visionary;" but who, let me ask, in the days of Job Charnock,--only 120 years ago, when he founded Calcutta--would have dreamt that that wretched, swampy village would have been converted into a city of palaces, and still less, that instead of a tedious sea-voyage of six or seven months from the mother country, it would be brought within the brief limits of forty-five or fifty days! Again let me ask, who only a few years ago would have conceived the possibility of a mode of communication whereby intelligence may be transmitted, not only by land but by sea, with the rapidity of lightning. Nay, that 4,000 miles of electric wire have already reached Calcutta, soon to connect every large town in India with the port of Bombay; while at the same time the submarine telegraph is in progress from Suez to Trieste, and before the expiration of 1855, will enable us to hear from our friends in any part of India in eleven or twelve days. Calcutta is so well worth a visit, that notwithstanding the numerous and able descriptions which have been given of it by various writers, I would strongly advise all who have it in their power, to become personally acquainted with it. This can now be done in so brief a space of time, and with so much ease and comfort, that many persons will be glad to avail themselves of the opportunities now offered, and desire to know the readiest way to accomplish this object. I shall therefore note down a few data, as to the best mode of spending a pleasant and profitable six months in visiting the chief cities of India.
