WEDNESDAY, 31st MARCH.--The journey from Bombay to Kurrachee by sea may be looked on as the first stage on the way to Kandahar, the second being the railway journey from Kurrachee to Sibi, a distance of about 530 miles. Till quite lately only a portion of this distance could be done by rail, which last October only went to Sukkur, leaving 131 miles of desolate desert, for the most part, to be traversed on horseback. In October last it was decided to begin the railway to Kandahar, and the work was put in the hands of Sir Richard Temple (assisted of course by skilled engineers), who was told that no money or exertions were to be spared to complete the line as far as Sibi, so as to avoid the awful journey of nearly 100 miles across a sandy desert, without water and without shade. Owing to the extraordinary energy displayed a feat was accomplished which, I believe, has never been approached; as a train drawn by an engine entered Sibi, 131 miles from the junction with the old line, in 101 days from the date on which the first sod was turned, being at the rate of 1⅓ miles of line each day. No one who has not had to cross the great Cutchi Desert, which lies between Jacobabad and Sibi, can, I believe, imagine what a terrible journey it was, but the number of men and animals who have died of thirst and heat in trying to cross it, proves very clearly the horrors of the journey. Now one goes through it in a comfortable first-class carriage during the night, and the discomfort and danger is a thing of the past. The train for Sibi leaves Kurrachee at 6 p.m., at which hour our party of the "Umballa," reinforced by William French and his horse, left for the second stage of our journey. The evening and night was fairly cool, and we all slept very well all night, having passed by Hyderabad about midnight, and not waking until we were 200 miles on our way. [Sidenote: By rail to Sibi.]
